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

36xbr800 sometimrs will turn on sometimes won't


it may be open contact on the flyback or
bad solder in standby power supply

Give it a smack open hand on the side
or better yet if you can have someone press
the power button as you rock it back and forth
this can tell you if its bad solder some times.

I suspect you crt tube is going and is most likely not worth fixing

There are things you could do a tv service shop could rejuve your picture tube and adjust your screen voltage.

sometimes that does not work

I would start looking for another tv
