Tv gos off turn on it gos right off will not stay on r52WH74


the trouble with the tca itc 222 chasis is that there is about 25 different resons that what you describe called a shutdown condition will occur. The first thing to know is that its not a main fuse problem.. the processor is recieving power and is detectecting a condition that is causing it to shutdown for safety. The top reason for this shutdown include a shorted Horizontal Output transistor, A bad flyback transformer. There has been reports of bad capacitors cp150, Technicians have special computer equipment that they plug in to read "error codes" that can help determine the problem. unfortunatly unless your a techniction these sets can be trouble to work on. I work on these daily and still they are trouble

Picture Flickering


The sony tuners have been known to get intermittent, it might be a bad ground where the tuner connects to the main chasis, If the problem is in the tuner itself it will be most difficult to resolve since the connections are so small and compacted together.
Good luck

Problem with tv turning on and off


Does the green light begin to flash when the picture disappears? If so, you have a weak lamp causing your TV to shutdown the picture. Replace the lamp with an original Sony lamp as the aftermarket lamps are known to have problems such as early failure and low brightness. Please be sure to rate this solution. Thanks!

Sony 36XBR800 Standby light flashes ...no picture sound


Hello,

For 6 blinks,Pls check following area.

Low HV Shutdown:
On the D Board.
Check IC8004/pin 7 should be 7.4v.
Check IC8006/pin 2 should be 2.5v if lower will trigger shutdown by causing pin 1 to turn on.
Check IC8006/pin 3 reference voltage 2.2v.
IC8006/pin 1 normally at 0v. If high
turns D5007 ON which turns the latch circuit Q6532,
Q6530, and Q6527 ON and turns the AC relay RY6501 OFF.

And NOTE: 6 blinks also can be Low B+ protection.

Unregulated 7.5 v from the power supply to 5v reg IC504 on the A Board. 5v to M Board Q2314

to CPU IC2300/pin 43. If 5v missing set will shutdown with 6 blinks.

I think this will help you to solve the issue.

Dont forget to Rate!!

Good Luck
