A 4 flash shutdown is a vertical stop condition, meaning that the vertical deflection circuit is shutting down.You need to purchase the service manual from :-
Once you have the manual, check the plus and minus 15 volt supplies on the G board. They are fused and the fuses are the easiest place to check them. If the fuses are blown, I would be thinking a bad convergence IC, as that is a common failure on these sets.
Let me know,if needed further assistance.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!

It sounds like the backlight or an inverter board on the television may have failed. Check your warranty status on the television to see if you can get it repaired by the manufacturer for free.

SOURCE: SONY-LED BLINKS 10 TIMES
OK, 10 times is HV protection (High Voltage) and problem can be in D board and Q8013, Q8014 can be shorted along with R8051 open.
also IC8005 can be damaged.
All above parts on D board.
I would recommend to get related service manual for proper diagnose of problem in TV.

You might have a bad lamp. RCA DLP projection That is the most comon problem with them. CRT rear projection, Red,Green,and Blue tubes.If it is the silver one w/the black speaker grill. Chass # _ _ _222 ?
Has 222 in the number.Can be several problems. Many things go wrong in those. Horz. Output,Flyback,And bad soldering are the most common problems w/those. Recomend staying away from RCA. Not the same company they once were.

From what you have said , Replace both of your STK ICs they are big black ICs will have part number on them example STK392-110
Go by the number printed on them if they are 110s use the 180s they are better ICs Mats has them for $10.95 each 1-800-628-1118
Also go to this website/use Google Encompass Parts Distrubtion
1-800-638-3328 sometimes they will have free service manuals you can print out.
Another thing you need to CK pico fuses they will look like resistors only they are green or yellow 5amp/ 6amp fuses Look in front of ICs and some are located behind ICs.
