Sony Bravia KDL-xbr4 Replaced TCON board All worked great for a week Had an issue w/ HDMI cable at the box fixed it and now tv comes and the goes off to 6 blinking red lights


6 red flashes- backlight issue, bad main board, or power board or inverter boards- check standby volts on power board. "backlight on" volts should be 3-5v from main logic board then 24v to inverter


Have this from a youtube link find BUT
Better is to look first also on bad leaking or bulged capacitors thats better to replace in the bad components to get a repair because active components died on bad capacitors but after a while because on the build-in protection circuit by faults like deformed or leaking capacitors and even several fuse resistors then after replace a complete board again after a while you will may be get the same kind of problems again, take If you find some or much bad capacitors replacements 10 volts dc higher . begin with control on the power supply first of all.

No picture, but sound and everything else fine. TV only 8mths old. Sony KDL-22BX20D


send back in for warranty repair!!! that is what warranty's are for! go to sony,com and look for a warranty repair center near you. you have either a bad back light inverter board or broken back light tubes. if it has leds for back lights then the board the controls them is bad and needs to be replaced by manufacture.

Hello!Sony SDM-HS73 power-inverter problem


At this point you may have bad transformers, bad tuning cap, you need to check the frequency of the inverter oscillator to see if both of them are running at the same frequency, the bad one may not be. The Inverter/power supply is not made by SONY, Powernet makes the board. Please see what went wrong with the one I fixed.

One thing to keep in mind, when the board turn into carbon (blacken), it will conduct. The circuits operate at high voltage and high frequency.

Need information on a "Code 10" for a Sony Projector TV KP-57WS520


hello - Check Q8014 and Q8013 for shorts, leakage, or bad solder connections on the " D" board. If the transistors are bad, check R8051 and IC8005, also on the "D" board.

Hi
Thanks for using FixYa. Ten blinks on Sony HDTV means-- Check Transistors Q8014 and Q8013 on D- Board for shorts, leakage, or bad solder connections. If the transistors are bad, then also check R8051 and IC8005, these are also on the "D" board.

Please do rate the solution and revert for further assistance.

Thanks Rylee

Will not stay on , sound only for 3 seconds then turns off. Stand by timer light blinking


sony blinking lites are error codes, on an LCD proj set 3 means bad lamp, 4 a bad fan 9 a bad thermal fuse, on a direct view like yours its probably 4 or 5 blinks indicating a bad D board (sells around $250) .
or a bad video IC, so B4 you buy a D board you need to check the CRT board if it has one IC on it measure ohms across the B+ capacitors on the CRT board, if shorted the IC is shorted and also the supply resistor will be open on the D board, if its shorted the CRT may be NG.
If the CRT board has three ICs don't bother checking eem just get the D board.

Sony HS30 Convergance Issue


The STK ICs are located on the D board their locations are IC801 and IC 802 they are both STK392-560 and you will only have to remove the D board. Usually only 1 or 2 resistors go bad right next to the ICs heatsink. You can get replacements at the following link and they include installation instruction plus free tech support heres the link.
