My Sony, KP-51HW40, flashes green blips and then shuts down. The little red light on the front of the TV goes on and off eight times after the tv shuts down. IS there a part associated with this red flash code or is there something I can do to solve this?
OMG! My TV has been sitting in a closet for the last three years because I couldn't afford to have it fixed. I have googled now and then trying to find a cure for its green affliction but never found the right advice until tonight. I can't thank J19666566666 enough!! I just followed the instructions and presto! Working TV again! And just in time for the Oscars (which is like the Super Bowl for me).
The editor in me tweaked the instructions a little...
Its is real easy to fix. There are 2 screws holding the front speaker cover on near the bottom corners (there are plastic plugs covering the screws that need to come out first). Unscrew and remove the speaker cover (pull it out from the bottom a little then sort of down and out to get it loose but be careful because there are wires attached). Next remove the 4 screws holding the particle board panel in place. There will be a cluster of 6 adjustment nobs with a drop of white paint on each one (2 rows of 3 - do not touch the top row). The green is controlled by the bottom middle screw, Using a screwdriver turn it counter clockwise (to the left) ever so slightly (1-3mm) and there you have your TV back. Use the bottom right screw to adjust the red and bottom left screw for blue.
Thanks again so much!

My sony tv has sound when you turn it on but no picture. We have unplugged the tv waited and the picture would finally come up. We called sony support and all they told us is to unplug. this morning when i got up the sound was there no picture but after cutting the tv off several times the picture appeared. now to come back home and have the same thing happen. after cont cutting off and on the picture will appear the sound is fine. the red light does not blink after the tv picture appears. when you first cut the tv on it blinks then. please help??? after the picture appears i have cut the tv off and on and the picture comes on its when you cut the tv off for a period of time there is no picture but we have sound.
Picture is gone, has sound for awhile, then the sound goes off as well. When turning on the set the screen is very bright, then goes bright blue, then black. The power light flashes five times, then stops, then repeats. Any suggestions?
My LG TV
switch on no picture but short period of sound then nothing

Picture fades out, seems really bright then goes all blue..sound stays on,
Unfortunately, this sounds familiar. Many of these sony projections had bad crt's.(picture tubes). Now here is a secret I learned along the way. The short in the picture tubes is in the filament, causing that color to overpower all others and sometimes causing pix to disappear until set is shut off and back on. If you are very careful and use an insulated screwdriver, you can sometimes tap on neck of picture tube and knock debris from filament causing extended tube life. This is dangerous and must be performed with set turned on. From front of set gently tap on neck of tube(s) in question using insulated handle of screwdriver to make contact with picture tube neck. Picture will probably flash whichever color tube is contacted. Eventually, if picture stops flashing that color as much, you can sometimes get several more months out of your set without any problems. Only alternative is to try a crt rejuvinator or replace tubes at a cost of 200.00 each if avail. plus labor. Good luck, Russmann.

It's not only adjustment, you have to replace both STK 392-560 IC.

My Sony, KP-51HW40, flashes green blips and then shuts down. The little red light on the front of the TV goes on and off eight times after the tv shuts down. IS there a part associated with this red flash code or is there something I can do to solve this? Same problem. I turn the TV on and it looks fine for 15-20 seconds. After 15-20 seconds the colors slightly shift toward red followed by a green flash or two. There no picture with hte green flashes, just green. After the flashes the TV turns itself off. The red LED flashes 8 times repeatedly - 8 flashes, pause, repeat forever. I tried the solution about turning the center adust screw counter-clockwise with no improvement. Something tells me it's time to get a new TV ...
or a new lamp. you could first replace the lamp.
the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.

My Sony rear projection TV has three images that seems to be out of alignment. There is a blue image, A green image and a red image. What has happened and can it be fixed? Thank You, Art
It can be fixed, if picture is 3d looking it is what is called a convergence problem.
See attached photos of typical ones. This set uses two of the STK-392-560 convergence IC chips.
It can be a do it yourself repair but this does require being able to solder.
Parts cost would on EBAY be under 25 dollars.
Let me know if you want instructions, I have photos of the parts and the board they are on.
see attached photos.
SD TECH
THE CHIPS WILL LOOK LIKE THIS BUT HAVE STK-392-560 PRINTED ON THE FRONT IN WHITE.

TURN TIMER OFF. GO TO SONY.COM, TROUBLESHOOTING, OR
The STANDBY light is flashing on the television and there is no picture or sound.
Solution
The STANDBY light will flash if an issue is detected within the television. This can sometimes be resolved by simply following the steps below to reset the television.
If the issue is still unresolved after following all of the troubleshooting steps, service may be required. Please note the number of times the STANDBY light flashes and relay that information to the service center.
