Make Model Symptom Problem Solution By
SONY LE3973
The LED would turn on and then turn off, flashing the red LED 6 times, indicating that the defect was on the inverter board. You take 3.3 volts from the power supply board and place it at the point on the inverter board wsound tsound are the olps and connect it and it will work beautifully. Diego lima
SONY KDL-32BX425
Turns on normally, turns off after a while Temperature sensor Changing the sensor board, or eliminating the power supply to the temperature sensor eletronica monteiro
SONY HCD-GTX88
Doesn't play pendrive CD carousel not working You have to fix the CD to get the pendrive EletroClaudio
SONY KDL-40EX605
When you turn on the TV, the red LED flashes 5 times Fuse open in t-con-cause - capacitor - c11 shorted in t-con. Replaced the capacitor and the TV fuse worked TV CENTER- FRANÇA
SONY KDL-40BX455
TV turns on the green LED and then it flashes red 4 resistors in series of 643 (640k)...changed Replace and scrape the plate underneath them! Antonio
SONY KDL-46EX505
Turns on, lamp flashes and goes off, normal sound and video, backlight off. Defective power supply board transformer. replace power supply board for another tested one. The power supply transformer makes a loud humming sound, replace it or the entire power supply. Maike SR
SONY KLV-32S300A
Does not turn on, red LED flashes twice Ps6203 open Changing the power supply's secondary f-4, in my case it did the trick. Maike SR
SONY KDL-40R485A
Turns on LED flashes 5 times Shorted capacitor cd 8 on the display ruler Replace or simply remove Dj Velk
SONY MHC-GTX888
Doesn't start 12v transformer open, and diode d1200 shorted Replace transformer and diode solved Lino
SONY KLV-40V410A
Frozen image with horizontal stripes with no response from remote control or panel. I checked all the power supply voltages (+12,+15, +5v), the panel lit up normally with the image frozen in horizontal stripes. I resoldered the 2 BGA ICs that are below the heatsink, after this process the board worked perfectly again, I tested it for 48 hours with direct connection and so far it is perfect. cdias
SONY KDL-40EX405
Does not turn on, turns green, turns to red and flashes 5 times Tcon fuse open HP ELETRONICA
SONY KDL-40R485A
Turns on the image, turns off. restarts 3x and goes to standbay and the LED flashes 6x after the third time it turns off Capacitor 39/50v Replace smd aluminum electrolytic capacitor on the 39μF/50v main board, it is close to the 9500 position i.c, i.c that powers the leds... MIGUELTV
SONY MHC-DX70
Push power protection At first it would be the STK outlet, but when I opened it I noticed that tsound was a very dry factory glue between c596 and c546, hiding r561 and r511. I removed c596 and c546, cleaned the area and realized that r561 was open. I replaced r561 and r511 with 100Ω film resistors, following the service manual. Rodrigo Lamego
SONY KDL 46BX455
No image, just audio. lamps off. Inverter fuse open and transistor shorted on the inverter board Test all the transistors on the inverter board. one of them will be bad. and of course replace the fuse. eletrocell info
SONY KV-29FS110
Press start power relay knocks but disarms and flashes 4 times successively. I did a scan on the board and it was constant that tsound was no +b so I found the c647 of 25v by 47 on the primary a and it released the +b but it was still in protection and I did a scan on the secondary and found the r592 of 0.33r open and c617 of 160 by 33 without capacitance. I replaced it and the TV worked perfect. Francisco Melo -Parintins-AM
SONY XBR55X905A
Curtain effect Display defect Throw it in the trash! Alessandro
SONY MHC-EC55
Turns on and off quickly as if it were protection. Transformer board relay Replace relay ry002 ELTON CASTRO

SONY KDL-46EX715
The power supply relay when turning on the TV, it keeps clicking Relay diode was leaking (d6303) Replace the diode for a 12v one and the TV worked yourosia eletronicos
SONY DIVERSOS
TV flashes stand by but doesn't turn on Some Sony TVs need to have exactly the same voltage on all LED bars, if one bar has a different voltage than the others, the TV may blink the stand by LED six times and turn off, or even turn the LEDs on and off. You either change this LED bar or find the LED that is causing this change. Measure all the LEDs on the bar with different voltages and replace those with voltages above or below the correct voltage. Sony normally 3 volts. Luiz
