Question about Sony FD Trinitron WEGA KV-36XBR800 36" TV

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

This happened all of the sudden, sometimes my Sony KV-36XBR800 will not turn on and the red led blinks 6 times, sometimes it turns on just fine, when it is on it works great. If you turn it off once it is on and the turn it on right away it will come back on no problem, do you have any idea what this could be and what it might cost to replace?

Unplug TV from power outlet and let it sit for a few minutes, then plug it back. It should work fine than.

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.

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

TV turns off but standby still blinking


Hello
Blinking of standby light in Sony sets are fault indications. Just count the number of blinks occur at a time, after switch OFF and switch ON your TV with its FRONT PANEL POWER CONTRO SWITCH. Make this test at least three times, and count the number of blinks keenly and inform me though Fixya. It will help me a great to rach to the faulty section, or even to the exact fault point sometimes. OK.

Light blinks 7 times when i try to turn it on. sony kv 36xbr800


Are you sure it isn't eight......try turning on this method....display, 5, vol+, power on. Should bring it on in the diagnostic mode. Mine and about kazillion other owners have the same problem, bad M board and they never issued a recall on it. Costs 2-300 to have someone repair it, cause its' too heavy to carry it in, I think they used cement in the bottom for weight.

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.

Sony KV-36xbr800 led flashes 5 times ??????


A common cause is the HV multiplier module is failing. Sometimes a failing CRT can cause this type of fault. There are other support components that can be going out of spec with age.

Considering the age of the set, I would be looking for a newer set. If you invest money in to this set, there is no guarantee that in a number of months from now there may be other faults.

Tv does not turn on


The power supply is in the protect mode. This is most likely a scan amplifier failure. Most of the time it would be in the horizontal output section. If the CRT is shorted, or there is a failure in the vertical section, this type of error will show. When there are scan amplifier failures, sometimes the power supply is also damaged and requires service.
