HCD-GT222
|
Does not read or recognize | USB controller board defect | Jump pins 4 and 5 of the IC915, it was not sending 5V from the regulator board to the USB connector! | Lucas |
| SONY |
KLV-32L400A
|
Turns on and off LED flashes 2 times | Fuse f4050 open, d4050 short and 1 capacitor short | Changing the fuse f4050 and capacitor and 2 capacitors to the d4050 in parallel: one was shorted | Wilson M da Silva |
| SONY |
KDL48W655D
|
Only lights up the LEDs without an image (only lights up LEDs) | Dirt in the fittings but it is very light, you have to clean it to see if it resolves it. | Cleaning the screen flat cable and cleaning the flat fitting on the board and screen side (clean with paper and cotton swab, then clean finally with contact cleaner) | Márcio Pereira |
| SONY |
FST-ZUX9
|
Cd and usb playing without audio (mute), normal aux and radio | Q501 and q502 leaky (this transistor switches the inputs) | Check pins 9 and 10 of the IC500, in the CD/USB function they must have the same voltage (9V) if they do not, the defect is in Q501 or Q502. | David Roger |
| SONY |
KDL-40R485A
|
Lights up the light, doesn't show the logo and goes out, with the LED flashing 5 times. | I found that the voltage above the avdd point did not remain, sometimes tsound is a short in one of the 4 filter capacitors on that line, in my case it was the ci itself, the icd1, bm81204, I put the sm4154 in its place and it went boom. | Davi.sls | |
| SONY |
KDL-32EX525
|
Without an image, sometimes the Sony logo appears, indicating a code with 8 flashes on the red LED. | Software problem, as I had another main board on hand, I swapped it and ran to hug it. | Replace pci main. | davi.sls |
| SONY |
KDL40R485
|
Turns on works normally and turns off randomly and turns on again. | Leak in on and off switch | The ideal would be to replace the key plate but as I couldn't find it, I dismantled and cleaned the on/off switch. | José Dias |
| SONY |
52EX705 40EX705 46EX705
|
TV flashes the Sony logo, turns off and flashes 6 times | Blown ps6800 smd fuse (below the LED bar connector, looks like a resistor) | I replaced the fuse with a 0Ω smd resistor and it solved the problem. | Darci Denzer |
| SONY |
KDL40BX425
|
Goes out after a few minutes and the standby LED flashes twice, | Cracked weld | Cracked print on 47r smd´ r942, just resolder it | SANTOMEL |
| SONY |
KDL-40BX405
|
TV turns on green LED, but does not turn on the backlight, note: this TV does not have silkscreen printing on the main board. | Short or leakage smd seramico capacitor on the main board. | 10μF smd capacitor. (measure with a ruler or caliper on the chip heatsink leg from right to left, 30mm horizontally and 16mm vertically. | RNSPTEC |
| SONY |
KDL-40BX405
|
TV doesn't turn on, the LED blinks three times. | Shorted or leaking smd capacitors, main board note: this board does not have silkscreen printing. | 10μF ceramic smd capacitor, measure (ruler or caliper) at the foot of the chip heatsink, from right to left 30mm | RNSPTEC |
| SONY |
KD49X
|
Streaks on the screen after half an hour on | Cleaning the flat cables and on CN3 of the T-board with the LVDS board, insulate with tape from pins 3 to 14, counting from right to left | Rodrigo cofferi | |
| SONY |
DVP-NS50P
|
Doesn't start. power supply voltages apparently ok. | Diode d315 and d317 in4002. | Replace without measuring. as indicated by in4007 and in the absence of it I put the rl207 it worked perfect. | RYK |
| SONY |
HCD-GPX33 HCD-GPX77 HCD-GPX88
|
Low sound without power and noise | Unbalancing in ic950 op amp | R971 and r959 both from 4k7 | Thiago paixao |
| SONY |
MHC-RG22
|
Loud sound at last doesn't go down | Two capacitors located on the control panel connected to the volume potentiometer c610,c611 change | Value 10k note: they look like resistors, replace them. | Joao |
| SONY |
HCD-EX660Z
|
The display lights up, but it does not turn on, neither with the power button nor with the remote control. | Change all toc keys on the pci panel. | Kleiton | |
| SONY |
HCD-GTR66
|
Turn on turn off | I already changed the output, it still had the same defect, turning off, analyzed the board was a leaky 2sc3052 smd lf transistor and changed all the electrolytics 47uf 10v, 4u7 50v, 100uf 10v, 10uf 100v and 2.2uf 50v | Resolved normal league | Andre |
| SONY |
HCD-GTR66
|
Doesn't start | The only LED stays on stand by, I've already tested touch keys, they're all ok, the defect was the 8mhz and 32.768khz crystal with a leak near the computer, I changed the device, it turned on | Resolved | Carlos |
| SONY |
HCD-GTR66
|
I'm sound | This device arrived at my workshop, with the following defect, it turns on the CD, USB and radio works normally, increases the volume to maximum, the audio is very low with hiss, this defect and in the ic400 r2a15216fp short, replace it with the other one and also around this ic change all the electrolytic capacitors without measuring them, they are bad | Resolved audio normalized | Andre |
| SONY |
KDL-32EX405
|
The remote doesn't work (remote control doesn't work on the TV.) | Shorted remote sensor board. | Sensor board, smd ceramic capacitor shorted, just below the infra. | RNSPTEC |
