At first, the image on the display disappeared, only the backlight. The radio tape recorder was working. Then there is something in the car welled up and dropped the battery overnight. In general, as I understand it, I turned it on when the power supply was too low. Disks stopped loading and does not read the flash card. The radio is on.
I checked the voltages at the panel connector. On the DSL bus 3V6 and on SDA 0V4. After soldering the pull-up resistor R111 SDA bus voltage and display recovered.
Now we see the anamnesis. We put the disk, the impression that with reading no problems, begins to unwind, then failure, the display shows interference and boots up again. The same with a flash drive. Writes "loading in progress" then failure and loads again.
I am inclined to the gathering of memory. Tell me what to do next with this miracle.
If your car radio is broken, then there is a chance to repair it yourself. How and under what circumstances this can be done, my master class with a photo will tell you.
The level of complexity of modern car audio equipment is such that if it breaks down, a visit to a service center is inevitable. Replacing the processor or changing the firmware at home is an almost impossible task.
But, if only the sound has disappeared in your radio tape recorder, it is quite possible to try to repair it yourself.
As a rule, replacing a microcircuit does not cause any particular difficulties - if, of course, you are extremely careful and accurate during repairs.
First of all, we measure the voltage on the wires to which the speakers are connected with a tester - the voltage relative to the case should be in the range from 6 to 6.6 volts. Since the amplifiers in modern equipment are made in a bridge circuit, isolation capacitors are not installed at their outputs, so touching the sound output wires to ground is unacceptable.
Video (click to play).
In our case, the voltage is present, which means there is a chance that the microcircuit is intact.
We disassemble the radio tape recorder - remove the top and bottom covers. Unscrew the screws securing the disk drive located at the top.
To test the performance of the amplifier, touch the legs of the amplifier inputs with your finger. You can use a thin screwdriver or tweezers, but in this case you need to be more careful - accidental shorting of adjacent pins of the microcircuit can disable it.
The photo shows that from the row of microcircuit pins closest to us, the tracks go to the connector - these are outputs; the entrances are located in the second row.
Some models have a “Mute” button - of course, this mode must be turned off.
In our case, a background with a frequency of 50 Hz appears in the speakers - the microcircuit is operational, the malfunction is in another place.
We carefully remove the disk drive without disconnecting the wires and cables. Turn on the radio again and check the signal flow. To do this, we touch the bodies of electrolytic capacitors - there should be 4 of them near the microcircuit, according to the number of channels.
It turns out that the signal passes from the output of the microcircuit, but not from the inputs. We measure the operating mode of the microcircuit with a tester - the voltage on all legs is zero, and there is no short circuit to the case.
Next, we check the operability of the stabilizer microcircuits - two of them are highlighted in blue, they turned out to be serviceable. The third, highlighted with a red rectangle, has a zero potential at the output.
Warming up the metal protrusion of the base of the case and the leads with a soldering iron, we solder the faulty stabilizer.
The marking of the microcircuit is 78M09, i.e. stabilization voltage is 9 volts. We change the microcircuit and assemble the device.
If such a microcircuit is not at hand, and you can buy it only by visiting a district or regional center, you can use the simplest 9-volt stabilizer assembled according to any scheme on one transistor for testing - you just need to remember that the collector's touch to the device case is unacceptable.
If there is a microcircuit of the KREN8A or 7809 series, the task is simplified - they can be attached to the case anywhere.
We solder the wires of the homemade stabilizer to the corresponding contacts on the board and fix them with a piece of electrical tape or tape to prevent the tracks from peeling off when the wires are moved arbitrarily.
Turn on the radio - there is sound. I warn you right away that it is not worth using the device with such a surrogate stabilizer - as soon as possible, you need to install a “native” microcircuit, because dangling tracks do not decorate any apparatus.
Can you tell me the marking of the resistor r170 please.

If your car has a Supra SDD-3000 and you want to share it with other people, then send photos of the car radio installed in you, your opinion about its work, the name of the car model where it was installed, and your name or nickname to our E- Mail: and we will post them on this page of our site.
When choosing a car radio, first of all, you need to pay attention to the manufacturer. In fact, now the world's leading manufacturers of car stereos are producing very affordable models, with which even the Chinese are hard to compete.And if the choice is between bells and whistles and quality at the same price, then you should choose quality - this way you will save your time and nerves, and also get a good radio and sound as a pleasant bonus.
All modern car radios now come with USB. It can be positioned either in the front or in the back. The rear location is more convenient, since nothing sticks out of the car radio panel and does not spoil the appearance, and also allows you to connect USB to the standard connectors provided by the car manufacturer and are often located in very convenient and logical places.
Before buying a Supra SDD-3000 car radio, you should understand whether it will be convenient for yourself to use the basic functions of the device. How does the volume control work, are the main buttons for switching radio stations and tracks logical? This can be done in person, in our car audio store, or you can trust our reviews, which we write honestly and without any financial interests.
The Supra SDD-3000 head unit is called the head unit for a reason - this is the basis of the future system. Therefore, when choosing it, it is worthwhile to understand and design the composition of the system components and, starting from this, to understand which outputs or inputs should be present on the radio tape recorder, so as not to collide in the process of building an audio system with the need to replace the car radio, for example, due to a lack of line outputs. If your system has or is planning a subwoofer, it makes sense to take a car radio with a built-in sound processor, which has time correction. The subwoofer is usually located in the trunk and much further away than the rest of the speakers in the system, and as a result, it feels like it is playing separately from the speakers. The processor allows you to correct this nuisance, as well as to expose the scene in the center of the driver.
Most modern car radios have built-in Bluetooth. This is convenient both when talking on the phone and when listening to music from your phone wirelessly. Modern BT in car radios are made of very high quality, have an external microphone and provide high sound quality and excellent audibility when talking on the phone. The times when there were complaints about Bluetooth operation are long gone.
All modern car radios have the ability to connect standard buttons on the steering wheel, which are found in most modern cars. To do this, you need to buy a separate interface (sometimes it is built into the device), which is not expensive and quite easy to install. When installing a Supra SDD-3000 radio tape recorder in a modern car, you may very often need additional accessories, which we always try to have available in our store: an adapter frame (if the standard place for a car radio has a non-standard 1 DIN size), an ISO adapter (so as not cut the standard wiring) and an antenna adapter for connecting a radio antenna.
Well, the most important criterion that decides whether to take a Supra SDD-3000 radio tape recorder is of course the sound. Here you can listen to honest and independent advice from sellers or installers, or you can listen to the device before buying and understand yours or not. Our Autosound store provides such an opportunity.
The detachable front panel of the SDD-3000 multimedia receiver has a 3 ″ display. The disc player is multi-format, there is an equalizer with presets (Pop / Rock / Classic), two pairs of line outputs (plus a separate output for a subwoofer) are supplemented with a video output, an AV input, an input for a rear view camera, and a USB port is provided for external sources. front panel and SD / MMC card slot. The supplied remote control is of the card type.

the sound is, so to speak, normal (for Made in Chiny, it's not even bad) but the radio is terrible (the panel is interfering - the hiss gets on your nerves.) The sound spinner is buggy at times ((((( the display of small tracks is not visible at all ((((and you can't watch movies without a magnifying glass
