  1. Two blinks - B+ over current protection (OCP), unit goes to the standby mode then displays the 2 blink fault. Could be a short in the power supply of any of the circuits.

SOURCE: Sony kv-40xbr800 won't turn on, blinks 6 or 7 times

there are two large electrolytic caps on the D board located on the same side as the hv xformer.
both caps are 1200ufd at 250v, replace C6503, it is futher away from the side of the pcb.
this is the part of the ac rectifier that feed IC6501 chip MZ3001D
cap size is 1 1/8" diameter and about 2" inches high.
my problem with 6 or 7 blinks, would go away temporarily after the tv was unplugged for 24 hours.
i verified the fix by attaching a 250ufd at 250v cap in parallel with the C6503.
the problem was corrected.
you must assume the cap is leaking, which leads to the intermittent failure.
parts and shipping are a killer, so i turned to ebay.
search ebay for "Electrolytic Capacitors, 1200 uF, 250 Volt, Snap in 2X".
as the only bidder, i picked up two caps for $3.99 + $3.50 s&h.
might be wise to replace both caps, C6503 and C6590.

Exact same problem. KV-40XBR800 wont turn on, blinks six times. I am in the process of changing both Ic's part# MCZ3001D with part# MCZ3001DB. Ordered them frm ebay and waiting for the new parts to arrive.
here are the pictures of both chips and after i removed them from the d board.
As soon as i receive the new ones i will put them in. I can't wait to see what happens and i wanted to say thanks to all of you out there for putting this thing up. Thank you very much.

I have a Sony Trinitron 34" tv. It will not turn on. The red light blinks 6 times then pauses and blinks 6 times again. Is this an easy fix or time to get a new t.v.?

hi,
ur tv has problem with horizontal output stage. check the horizontal output transistor. if it found short replace the same and switch on the tv. if the same fault occur again, then the lot (line output transformer) may be faulty. also check for any dry soldering in the power supply stage and horizontal output sage.
ok

My 36xbr800 blinks six times then pauses then blinks six times, this is repeated......

Check the voltage input to horizontal output transformer [LOT]. Check the voltage at the collector point of the line drive transistor. If the line drive transformer primary gets open this type of fault mau occur. Also check the frequency ant the collector point of line drive transistor and the base point of line output transistor. It should be aroung 15625 Hz.
Check and replace the horizontal output transistor if needy. Replacing it is better. The horizontal output is not working or a short in secondary power supply of SMPS or lot secondary, is your problem

Sony Wega 40" TV will not turn on, standby light blinks 6 times repeatedly

Hello,For model KV-40XBR800,

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.

Good Luck
