    I hope I unplugged the right board. I pulled off the CR board at the bottom of the yoke and V-board assembly. The tv still shuts off after the blue and green tubes light and the red doesn't and I get a 8 flashing light code,which is audio, I think.

No picture comes up but tv powers up and the stand-by light blinks for about 3 to5 seconds, i also hear sound when i turn it on and change channels


If in shutdown the power light should continue to blink a specific number of blinks which is a error code.

This set is prone to bad picture tubes (has 3) so depending on code may be a fatal issue----sets will before flash bright red, green, or blue when this happens and shut off.

3 blinks is a lamp cover error, did you make sure that the lamp cover is screwed in tight? Also check the lamp cover for deformity, there is a problem with your model where the set over heats and melts the lamp cover a little causing it not to make connection with the lamp cover switch. Let me know if you find either of these problems? If not we can troubleshoot a little further.

Inspect the lamp first to see if shattered--set has a self check feature also:

Here's something that might also be useful. After you turn on the set, and getthe regular red blinky lights, hold down the Device and Menu buttons togetherfor about 5 seconds.
The Power light will start to flash in a two digit sequence.
For example, 3 flashes, then 7 flashes = 37.
Here are the error codes, and the corresponding problem:
12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filtercover is open.
34 = Lamp abnormality
36 = Light Engine (DMD or Lamp Fan stopped)
37 = Exhaust or Lamp Ballast Fan stopped
38 = Lamp Temperature High
39 = DMD Temperature High
41 = Short is detected
44 = DVI cablebetween FMT and Engine disconnected

A continuous flashing red light with the word LAMP on it would definitely mean you're going to need to spend a few bucks on a new lamp....or for a few more, upgrade to a TV from this century that doesn't require lamp changes :)

On that particular model I believe there is both a lamp indicator light and then the power indicator light. If it is lamp related the lamp indicator light (LED that looks like a sun in a cup...) would be on.

If the power indicator light is flashing red to green, that is a self diagnostic code, and you will have to contact an authorized Sony repair fascility for them to translate the problem. The error codes are not listed in the user manual, since most are not user serviceable.

As you said your set uses 3 crt's red.blue and green.. not lamps.. If the red is not on it could be for several reasons other than the crt itself. From the driver ic located on the crt driver board attached to the neck of the red tube. It could also be the high voltage block or the anode lead going from the hv block to the crt itself. These carry a hefty voltage and will knock you on your but and make every filling in your mouth light up lol.. I recommend you having someone experienced check it out. As for the fluid, if the picture was good before it went out then that wouldnt be something to worry about. Removing the tubes to refill with fluid requires a massive alignment job afterwards.

Red power light and buzzing sound with red lamp light.


My Sony lost its picture and had a flashing light. Unplugging for 36 hours solved the problem.

Power turns off and color is off when first powered up

this model is famous for fluid leaks. each projector True True (``````````` (``````````` 0 95250 95250 clip_image002.png tube has a reservoir on the front of it with a fluid in it. this keeps the face of the tube cool.
this depends on how bad the damage is in the tv. in most cases we can reseal the tube and clean up the fluid 400-600.
Once you
take the tube out you will see where it leaked. The problem is that the
frame on the CRT that the heavy screws with springs are mounted on (that
hold the lens coupled to the CRT) is weak and they can bend. We have seen
several that have leaked after the customer moved the set. You can only
tighten them down so much because the frame bends. It is just stamped metal
and not welded at the corners to support the bend.

We remove the CRT, clean it all up, add a very small amount of RTV sealer to
the gasket, reassemble, let the RTV cure thoroughly and refill with coolant.
The extra sealer should prevent future leaks. Haven't had a recall yet.
Mits says replace the CRT...too costly.

You msut check the yokes carefully as well. If any coolant gets into them
you can end up with shorts there and a mess.

No picture coming from red lamp


Sounds like you have two differant problems. A red drive or red picture tube is bad and the conbvergence IC's are bad. To test the red drive disconnect the green picture tube socket BUT MAKE SURE THE SET IS UNPLUGGED!!Then remove the red socket and move over to the green tube. Then turn on the set. If you get the same out of the green then you have a drive problem that needs to be trouble shot for a bad componet. If you do get a picture with the red connected to the green then the red tube is shot. If you know how to read a schematic, get one and then you should have no problem troubleshooting the red drive and the convergence problem. If you dont then there is no easy or quick fix as this is a solid state set and there are no user replaceable parts inside this.,. Your going to need, for safetys sake, call in a trained tech to assist you with this repair
