In detail: world vision t34 do-it-yourself repair from a real master for the site my.housecope.com.
It is necessary to explain it as for a beginner, those who understand will do everything themselves.
Good afternoon. I need your advice. The t54 prefix was plugged into the 5 volt place at 12 volts, after which the LED does not light up. What could have burned out. Thank you. along the circuit at the beginning there is a 15cfb microcircuit after there is a throttle on which there is no power. I think that this very microcircuit burned out.
Hello. At work, the guards drove this device. They say it worked, then the signal disappeared. Turned off, turned on and nothing. The green LED is on. They gave it to me, they say, look. Brought home, disassembled, turned on. The green LED is on, the processor on the radiator is not heating, the RAM is heating, 40 degrees. I measured the voltage, everything is normal. I connected an adapter to the UART, started the terminal. When connected to the network, the terminal writes: BOOTSPI and that's it. Not there and not syudy. Okay, I downloaded the firmware, flashed it through MiniPro, soldered it, the same bullshit. Although earlier about 2 months ago, they already brought it to me. Didn't work either. When I took it apart, I found several cockroaches, a big pile of cockroach shit. I washed it with hot water and liquid soap, dried it, connected it to the terminal, at start-up he issued such a footcloth on the port, and now there is only one inscription. Can you tell me where to dig further, I have never dug into these Chinese receivers. I would be glad if you answer.
Hello!
Receiver BBK SMP123HDT2. The problem is this: when you turn on the receiver, the TV works for 3-5 seconds. there is an image and sound, then everything disappears, the receiver turns itself off, goes into standby mode, the red light is on. When you turn it on again, the situation repeats. Sometimes, when turned off, the screen field is green. If you disconnect the antenna cable, turn on the receiver, insert a flash drive, then only the media player works in normal mode. Tell me what could be the problem? Maybe you have already encountered similar malfunctions?

professor prefix Oriel 303-image good sound fonit and changes when the picture changes. When you turn off the video output, the sound is good with no background. Tell me the reason
And if possible, a question. The same T59M prefix, after starting the channel search, passes 25% and turns off. Reboots and re-enables the basic settings menu. The CPU heatsink temperature is about 80 degrees and the whole circuit consumes 850 mA. current.
If not difficult, could you help me
There is a BBK SMP123HDT2 prefix, when connected to the network, green and then red lights up, there is nothing on the TV, respectively, I checked the voltage on the stabilizers, all voltages were checked except for 1.8 volts on the APS2408 stabilizer, I sealed it off, turned it on without it, the green is on, the red does not light up anymore, I thought everything is fine, I soldered the wiring to the choke, from the LBP I applied 1.8 volts to it, turned it on, and again the same picture, green then red lights up, nk tell me what could be the reason. Thank you in advance, best regards, Alexey
Thank you very much.
I dug everything, I did not find it.
I will call and dig on datasheets.
You are doing a great job!
Thanks a lot!
I'm looking forward to the next videos.
All the best!
hello, this is the problem the tuner t 57 turned on 12 volts, after checking it turned out that the diode burned out, which is after the power supply.
Good day. As I understand it, two ds-ds shims are used - the 1st with 5 volts makes 3, 3, the other (which you soldered 3, 3 volts converts to 1, 15v.
Question: can both shims be replaced with RT8059 or are there nuances? ... The shim that turned out to be serviceable for you (and it was serviceable for me during the campaign), the leg fell off, now I do not know how to change it. What do you advise?

How to operate with it without a remote control there is an option
Hello! a receiver breakdown made you contact your site. my green indicator is constantly on and shows one channel, the remote control is working, but the receiver does not react to the remote control in any way. Help, tell me what to do ??
If you yourself are a scientist or just an inquisitive person, and you often watch or read the latest news in the field of science or technology. It is for you that we have created such a section where the latest world news in the field of new scientific discoveries, achievements, as well as in the field of technology are covered. Only the latest events and only trusted sources.
In our progressive time, science moves at a fast pace, so it is not always possible to keep track of them. Some old dogmas are crumbling, some new ones are being put forward. Humanity does not stand still and should not stand, and the engine of humanity is scientists, scientific figures. And at any moment, a discovery may occur, which can not only amaze the minds of the entire population of the globe, but also radically change our lives.
A special role in science is allocated to medicine, since a person, unfortunately, is not immortal, fragile and very vulnerable to all kinds of diseases. Many people know that in the Middle Ages, people lived on average for 30 years, and now 60-80 years. That is, life expectancy has at least doubled. This was influenced, of course, by a combination of factors, but it was medicine that brought a big role. And, for sure, 60-80 years for a person is not the limit of an average life. It is possible that someday people will step over the 100-year mark. Scientists from all over the world are fighting for this.
In the field of other sciences, developments are constantly being carried out. Every year, scientists from all over the world make small discoveries, slowly moving humanity forward and improving our lives. The places untouched by man are being investigated, first of all, of course, on our home planet. However, work is constantly taking place in space.
Among technology, robotics is especially striving forward. The creation of an ideal intelligent robot is underway. Once upon a time robots were an element of fantasy and nothing more. But already at the moment, some corporations have real robots on their staff that perform various functions and help optimize work, save resources and perform hazardous activities for a person.
I would also like to pay special attention to electronic computers, which 50 years ago occupied a huge amount of space, were slow and required a whole team of employees to leave. And now such a machine, practically, in every home, it is already called simply and shorter - a computer. Now they are not only compact, but many times faster than their predecessors, and everyone can figure it out. With the advent of the computer, mankind ushered in a new era, which many call "technological" or "information".
Remembering the computer, do not forget about the creation of the Internet.This also gave a huge result for humanity. It is an inexhaustible source of information that is now available to almost everyone. It connects people from different continents and transmits information with lightning speed, something like that was impossible to even dream of 100 years ago.
In this section, you will certainly find something interesting, exciting and informative for yourself. Perhaps even someday you will be one of the first to learn about a discovery that will not only change the world, but will turn your consciousness.

The digital TV set-top box broke down - it just stopped turning on. The problem turned out to be in the power supply unit.
The World Vision T34 set-top box is a compact terrestrial digital receiver that supports reception of a signal in the DVB-T2 standard. Designed for viewing open federal channels that are included in the first and second multiplexes, which are broadcast in uncoded form. The compact dimensions of the receiver were achieved due to an external power supply unit with a voltage of 5 volts.
You can connect the World Vision T34 set-top box to a TV either using the HDMI connector, which improves the image quality, and using the composite output. The USB port allows recording programs to external drives.

Nikolay Good
Advantages: It's very good to have an external power supply.
Flaws: When switching to the menu, it translates the TV image into a mirror position, which is inconvenient and has to be corrected, and from USB there is no sound in MKV format.
A comment: I got a WV T34 for a truck, a 5 volt adapter is cheaper than a 220 V inverter. Satisfied.
Natalia Fine
Advantages: Small, inexpensive, separate power supply.
Flaws: Not
A comment: I bought the Signal receiver instead of the burnt out receiver, especially with a separate power supply unit, since it was he who burned out on that set-top box. This World Vision T34 has better sensitivity.
Oleg Bad
Advantages: Not
Flaws: It switches channels for a very long time, the power supply burned out.
A comment: I bought it for the kitchen TV, I need an additional socket for the power supply, which turned out to be somehow flimsy. For a long time I was looking for shops with exactly the same connector. When switching channels, it seems to fall into a trance, thinks for a long time.
Michael Good
Advantages: Inexpensive, external power supply.
Flaws: Slowly switches from channel to channel, but with friends Rolsen RDB 502N, switches in the same way.
A comment: I took it to the dacha. The figure justifies itself, the quality is at the level, the reception is stable.
Artem Average
Advantages: Inexpensive, the menu at worldvisiont34 is very convenient.
Flaws: The remote is small and has small buttons. The set-top box has only 2 channel control buttons.
A comment: Inside the remote control there is a “drop” instead of a microcircuit (cannot be repaired), so given that you cannot enter the menu from the panel, be careful with the remote control. If your antenna shows analogue channels poorly, then the digital will work with WV T34.

DVB-T2 set-top boxes for receiving terrestrial digital television in Russia on a conventional decimeter antenna have gone on sale.
Specifications
Receiving DVB-T / T2 digital TV signal
Decompression MPEG2 / MPEG4
Video Resolution Support: 1080p, 1080i, 720p, 576p and 576i
Multilingual menu support
PVR and Time Shift function using external USB drives
HDMI digital audio / video output
USB 2.0 connector
Play various multimedia files MKV, AVI, JPEG, MP3
EPG (Electronic Program Guide) for 7 days
Automatic and manual search for all channels
AC3 Dolby Digital Support - No
Dimensions (edit)
Length - 120 mm
Width - 104 mm
Height - 26 mm
The remote control differs from the T-40 model and is not compatible with the codes. In my personal opinion, the remote control of the T-34 model is much more convenient. The buttons are softer, the dimensions of the remote control are larger.
You don't need a specialist to connect the set-top box.
Enough:
Pull the antenna cable out of the TV and connect it to a suitable connector on the set-top box (see the photo of the rear panel, the connector is on the far left)
Connect the set-top box to the TV with an analog (bells, they are tulips) or digital HDMI cable.
Connect the external power supply unit (supplied in the kit) to the electrical network and to the set-top box
Turn on the set-top box, use the TV remote control to switch the video inputs (see the instructions for the TV) until the set-top box menu appears on the TV screen.
Use the STB's remote control to start the autosearch of channels - just by pressing the OK button, wait for the scan to complete.
If everything is in order with your antenna, after a while you will see 29 TV channels, some of which are Crimean (local).
The set-top box is required for all types of TVs, except for those equipped with their own DVB-T2 tuner (see the TV specification on the manufacturer's website). Having a DVB-T tuner without number 2 will not allow you to receive digital TV without a set-top box.
Attention! The power supply unit of the set-top box is 5 volts. If a third-party 12 volt power supply is connected by mistake, the set-top box fails, which is not a warranty case.
It is forbidden to connect external USB HDD drives to the USB connector that do not have their own power supply, or with one, but with poor fixation of the power cord from the power supply.
Pressing the Information button
Double-click the Info button
Pressing the EPG button
Draw your attention. There are 29 channels in Sevastopol. Added the First Sevastopol.
The delivery set also includes an external additional photodetector for remote control signals. Its presence allows you to hide the receiver in furniture or behind a TV.
The T2 receiver was repaired after a thunderstorm with the declared malfunction does not turn on.
PCB marking and board number DVB-MPEG-185G-VER1.0
Measurements of the PWM power supply of the PN8136 controller showed that the microcircuit was in a short circuit.
After dismantling the microcircuit, the short circuit disappeared.
And here is the dismantled PN8136 microcircuit itself
We change the microcircuit to a new one and try to turn it on.
Well, the final stage of the repair is to test the operability of the World Vision T55 receiver.
Just in case, I'm posting the firmware of this receiver.
The people are silent for the time being. 46 views meanwhile ... So while the interest of the author of the blog has not disappeared in his new brainchild, we will try to ask him topical questions. And there others will catch up ...
And why should he disappear
Hello! Such a prefix. I got caught in the rain. Itself seems to have survived, but the primary is bent. Changed 431 - optocoupler (817) - PN8136 - lithic 10 * 400 - the whole bridge - fuse ... Ie. what was found to be "broken" or suspicious.
With the impudent connection of the +5 source, the prefix works. But from the network no. There are even generation bursts at 7.8 feet m / s, although 290v is available. Under suspicion of a trance (water also got on it), but there is nothing to replace it with.
