a guest , you need to wave harder, then you will learn to fly
First, check if the disc is actually rotating in the set-top box when the case is removed.
Can you help me?
If absolutely at all games, then Khan.
often ask for a pressure plate for a Sony Ps1 CD drive, tell me where to buy them (especially in Ukraine) .Thanks
I don’t know where else
cut out the circle evenly in the old sidirom, more than there is in the gut
Video (click to play).
attach is no longer a problem.
In PS1, the disc is loaded but does not respond to the joystick. Advice is required.
If you have a PS one, then first check all the fuses for power, you can start from the very positive contact on one of the joystick ports, if power is supplied, then next to the second port there is a small gray light-colored diode, call it, and for faithfulness you can even to drop it out, it is not necessary to work, if without it in the main menu of the BIOS the arrow of the joystick appears, then everything is ok, but the diode mainly lights up when someone incorrectly solders the wires to the joystick or the Chinese joystick burns out.
If you have a large model, then ring the fuses, with the exception of the fifth series model, diodes may also fail there.

Problem! Joysticks work if you insert a normal audio disc as soon as you insert a game disc the joysticks do not work. who faced what the problem is, help.
people, and did not meet with such a problem. some games restart out of the blue. some in certain places. I don't know what to think
for Areon and UNIT, thoroughly warm up the CPU and memory with the station. in 99% everything starts working.
This little spinning round thing that turns discs in SonyPS had three silvery little balls. I suffered from nonsense, pulled them out and lost. Discs do not want to spin anymore. Sometimes, grunting, they spin. More often than not. Games are not loading. What to do?
Catherine_Elizabetha ,
I inserted these three balls
Catherine_Elizabetha , So you broke and the clamps from which the springs also fell.
Give a link to the repair encyclopedia
And then I click on the link, and they return me to the same page
In general, I repaired the dormouse, everything seemed to be fine, but I did not like the work of the SD-rum, I put it on the spindle, the image and sound disappeared, one of the mikruhs began to warm up, I disassembled, assembled, supplied the power, the disk loads, but there is still no sound and image ... What to do?
Hello dear, help me eat the sony ps one dock after a power surge does not turn on. bp the circuit works there is where to dig please tell me
Guys a problem. The motor does not spin! The motor runs 100% tested by the power supply. Where to dig ??

PS one: maintenance and repair
The video game console “PS one” by the Japanese company Sony is the result of the development of the series of consoles “PlayStation” [1]. Small weight and dimensions leave an imprint on the features of its operation. Compared to previously released models, "PS one" often suffers from accidental falls from a height, you can literally sit on it without noticing it on a chair or sofa. As a result, it is necessary to more often glue the cracks in the fragile case of the attachment.
To protect “PS one” and its accessories (joysticks, memory cards) from premature failure, make a rule not to dock or disconnect the connectors when the green indicator on the front panel of the set-top box is on. And if you really had to do this without turning off the power, apply force strictly perpendicular to the plane of the console body. This ensures that the longer power and common pins in the connector are connected first or disconnected last.
There are no very hot elements in “PS one” and it can be left switched on for a long time. The network adapter, which continues to work even after turning off the set-top box itself, is designed for long-term “idle” operation. However, it is best not to leave it unattended and unplug it from the wall outlet at night or when leaving home.
The body of the video set-top box adapter is plastic and. non-separable to resist the age-old childish desire to look, “what's inside?”. By the way, a similar design is increasingly used in various household appliances. To gain access to the adapter board, carefully saw through its body with a thin hacksaw along the side along the perimeter. After completing the repair, glue the halves of the case or simply wrap it with several layers of adhesive tape, preferably transparent.
In the network adapter, the 2 A fusible link F1 most often burns out ([2], Fig. 5). This is often a consequence of the breakdown of a powerful field-effect transistor Q1, which can be easily replaced with one of the similar switching power supplies for TVs (FS5TM, 2SK1117, 2SK2666, 2SC2128, 2SC2125, 2SC2718). The transistor must be rated for a voltage of more than 600 V and a forward current of at least 5 A.
Transistors used as Q2, Q3, Q51 are produced by many Western and Asian firms. If necessary, they are replaced with any low-power corresponding structure (p-n-p or n-p-n) and sizes, for example, series KT3129, KT3130, KT315, KT361.
The closest in parameters to the one installed in the adapter (IC1 microcircuit) is the NCP1200D60R2 SHI controller from ON Semiconductor. Optocoupler IC2 - any with an isolation voltage of more than 500 V (NEC2561, TLP621, TLP521, PC817A, “3171”, “3131”). Diodes D3, D4 - 1 N4148 or series KD521, KD522, KD503.
In case of complex malfunctions, it is advisable to refuse to repair the adapter and replace it with any, even a home-made and not necessarily a pulsed network power supply with an output voltage of 7.4. 8 V at a load current of 1.5. 2 A. A lower voltage is not enough for stable operation of the set-top box, with a higher voltage, some of its elements will heat up too much: an integrated stabilizer IC601, transistor Q602 ([2], Fig. 4), IC722 microcircuit (Fig. 3, ibid.).
The appearance of the processor board is shown in Fig. one.
All important elements are marked here. If there are no clearly damaged parts, for example, blackened resistors, on the board, regardless of the nature of the defect manifestation, all fuse-links in the design for surface mounting must be checked first (Table 1).In good condition, the resistance of any of them does not exceed several tens of milliohms, a larger value indicates partial or complete operation (burnout).
If the failure was the result of a supply voltage surge or an accidental short circuit in the joystick, replacing the burned-out insert with a similar one or just a piece of wire with a diameter of 0.1 mm usually completely restores the operation of the IVP. However, after repairs, it is recommended to watch for a while to see if the fault reoccurs and if there are unusually hot parts on the board.
Quite often, the protective zener diodes installed in the input and output circuits of the set-top box near the CN502 connectors fail (their failure leads to the absence of an image and sound) or CN101, CN102 (joysticks and memory cards do not work). For example, when the stabilization voltage of the Zener diode D104 decreases to 1.8 V as a result of a malfunction,
Some joysticks continued to work, while others did not. Zener diodes can be replaced with conventional KS147. KS168 with any letter indices, although it is better to use special limiting diodes [3]. Less often, there are breaks in the windings of the inductors and noise suppression filters, which should also be checked with an ohmmeter.
Mechanical damage to the processor board and its elements is not typical for “PS one”, although there have been cases of short-term power failure due to poor contact in the J001 connector. Sometimes the attachment cannot be turned on because the contacts of the S001 switch are oxidized or burnt. Greater reliability of the circuit breaker can be achieved by connecting a free group of its contacts in parallel with the operating one. A break in the hinged conductor going to the IC801 microcircuit once led to the fact that when any game disc was installed in the console, a music menu appeared on the screen.
Table 1 will help you choose a replacement for failed transistors (including those installed in the network adapter). 2. It contains not only the main parameters of each transistor, but also the marking applied to its case, without knowing which, it is rather difficult to “identify” the device.
Set-top box resistors are usually marked in a standard way. Of the three or four digits of the code, the far right is the exponent of the number 10, by which the number indicated by the previous two or three digits should be multiplied. Examples:
However, resistors from "Bourns" are also installed with a tolerance of ± 1% and alphanumeric marking. To decipher the digital part of the code applied to a similar resistor, refer to table. 3. The number found in it is multiplied by the coefficient indicated by the letter: S - 0.01, R - 0.1, A - 1, B - 10, C - 100, D - 1000, E - 10000, F - 100000. The result is Is the resistance of the resistor in ohms. For example, 12C - 13 kOhm, 18V - 1.5 kOhm.
The weak point of all PlayStation models, including the PS one, is the mechanics of the CD-ROM drive. Prolonged daily operation of the attachment leads, as a rule, to the backlash of the rotor of the motor rotating the disk. Outwardly, the defect manifests itself in the fact that in the normal (horizontal) position of the IVP case, the game programs begin to work only after repeated “fidgeting” of the laser head on the disk. By tilting the case 10.45 °, the reliability of data entry can be restored. Sometimes the angle required for this stabilizes over time, but more often it gradually increases.
Having found such a defect, first of all, make sure that it is the motor that rotates the disk, and not, for example, the drive of the optical head carriage. The worm gear of the drive is worn out, sometimes its action is impeded by accumulated dirt. Wash all transmission parts with pure ethyl alcohol and lubricate with medical petroleum jelly or a special non-thickening grease for plastic parts (MOLITUBE, LUBRIPLATE, etc.).
To eliminate the "jerking" of the carriage, sometimes it is enough to slightly displace the motor that rotates the worm, or to drip lubricating oil onto its rotor.If the drive is working properly, the movement of the carriage should not be accompanied by crackling and other sounds.
An unreliable reading of the data may be due to the lens of the optical head being dirty. This is often the result of the deposition of tar from tobacco smoke. The surface of the lens is blown with dust-free compressed air from a special aerosol-like canister or gently wiped with a clean, dry cotton cloth. It is acceptable to replace a lens with a similar 5mm diameter from a computer CD-ROM drive.
Sometimes it is useful to increase the power emitted by the laser diode by decreasing the resistance of the substring resistor located on the flexible ribbon cable of the optical head by 10.20%. Before adjusting, measure the set resistance value (approx. 1.2 kOhm) so that in case of failure, return everything back.
If, as a result of the measures taken, there is no improvement, the safest and fastest repair method is to replace the entire CD-ROM drive unit with a known-good one. In addition to the standard one, you can use the KSM-440ACM drive from the SCPH-100 x series consoles. KSM-440ADM, KSM-440AEM actuators differ from other “PlayStation” models in the length of the flexible cable and design, although they are electrically compatible with “PS one”.
Please note that the cost of this operation will be 35. 50% of the total cost of “PS one”. A cheaper option is to replace only the CD-ROM drive motor. RF-300PA-11400 D / V 5.9 or RF-300F-11420 D / V 5.9 from Mabuchi will do.
In a hopeless situation, you can go for an independent engine repair. It, together with a plastic nozzle 2, is schematically shown in Fig. 2. The latter must be removed, having previously measured and recorded the width of the gap S between it and the engine housing 1. This will allow the part to be returned exactly to its original place. Please note that the unit is not designed for disassembly and reassembly, the operation is not always successful and requires certain skills.
The nozzle is very fragile and fits tightly on the shaft 3. Removing it, you must not allow it to be skewed, which can lead to irreversible consequences: bending of the shaft, cracks in the nozzle or a “broken” bore that prevents it from being fixed on the shaft in the future.
It is best to make a special puller - a lever with two blades that are inserted into the gap. With its help, the nozzle is gently shifted, applying efforts evenly from all sides. This operation can be performed in another way, for example, using several steel plates inserted into the gap from different sides. The main thing is to act carefully and without haste.
Rinse the entire surface of the shaft freed from the nozzle with ethyl alcohol. Then, putting on protective gloves, with a drop of cyacrine (this strong, quick-drying glue is sold under the trademarks "Instant Superglue", "Seconds"), fix the shaft in the sleeve bearing 4, eliminating the backlash. After a few minutes required for the glue to dry, the nozzle 2 can be installed on the shaft 3, making sure that the width of the gap S is exactly equal to the one measured before the start of the repair. If the bit slips on the shaft, try to fix it with the same adhesive.
A day later, you can start "training" the engine voltage increased to 8. 9 V. At the first start-ups, the shaft will accelerate slowly, as if with difficulty. After a few “workouts”, normal rotation will be restored.
Cyacrine is able to firmly glue biological tissues, so it should be used with caution, avoiding contact with the skin.
