Good day.
Your unit has issues with the high voltage section. Particularly the vertical and horizontal sections. Blinking lights indicates that your flyback is not osscilating to distribute the supply to the sections. Please have it checked by a repaiman.

SOURCE: Sony KV-36XBR800 won't turn on and red led on the front blinks 6 times

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 this issue..

Dont forgety to Rate!!

Good Luck

SOURCE: Video Labels stay on - Sony TV Model KV-32V16

Press Display / ' i ' button TV original remote and on-screen display will disappear.
I repeat, you need Sony TV original remote to do so, universal remotes do not have such button.

Sony 27"TV will not turn on


The picture tube on your tv is dead, you need to replace it. It probably will be worthing just purchasing a new set, because the cost of repairing it will be close to the purchase of a new one.

The set may have shorted the horizontal out put transistor since it kept coming on sometimes. This could be cause by the driver transformer arcing causing a "spike" in voltage going to you horizoltal out put transistor. Stargazer

You may have a bad solder joint on the horizontal driver transformer or somewhere else in the set. I found this problem with this transformer several times. Stargazer
