My TV thinks it's a launchpad...

I get a message after having the TV on for 2 or 3 hours. In the lower left-hand side, blue with white letters stating "No Operation Off" followed by numbers that count down until it turns off.

Screen goes black, still have audio


I first changed the 220uf capacitor with no luck. I flipped the BURN switch to on and the set has been working great for a week now. Daughter left it on for about 20 hours overnight with no problem. Anybody have an idea what those 4 tiny switches are for? I have heard these type of switches called "dip switches". They are tiny white switches in a yellow block on the lower left side of the upper circuit board. The top one was labled 40", the next one down was labled 46", the 3rd one was 4 letters "EW" something I think, and then the bottom one was labled "BURN".

Have the same problem...the lower right and lower left hand side


Your TV is going bad. You can get a booster to put on the back, but it can be quite spendy.

Sony WEGA KE-37XS910


This TV has a very expensive panel... we are talking $3000 core charge alone! It comes complete with all the lower buffer boards (which from the sound of it, you are having a problem with). Individual boards for this defect are not available on repair parts list I know of. A panel is what you need, PN: 9-885-063-33

Error message


I found this solution in the web and it worked!

The slider on the left hand side (i think) of the machine has slipped. Remove the cover, and you will see a large white cog with a white vertical slider behind it. On each you will see a small arrow. You have to remove the cog and line up the 2 arrows on the cog and slider and then reinstall the cog. This should solve the issue.

The left hand panel of the laser printer was a bit tricky to get up but a bit of perseverance. Then remove the white cog by releasing the two tabs round the center metal pin. You need to align the vertical slider's pointed end with the horizontal slider's arrow precisely as even slight misalignment will not fix it. Then fixed!

HC-P4752W Blue Convergence??


You can replace the whole board, or opt to replace just the 2 IC's and a resistor or 2 that has probably failed. Lift the chassis & inspect the pins of the 2 IC convergence chips for hair line cracks around them. Inspect the small resistors out in front of the IC's for discoloring or burnt look compared to other similar resistors. The convergence board will cost much more than having the above repaced. Chips about fifeteen a piece, resisters .50 cents each plus shipping. Convergence board $100 plus.

Convergence problem


We need a better description of what you mean by shadowing. However I am assuming: 1. You mean it ''bleeds'' off to the right when you have something with a hard red/blue drive. 2. When you turn the contrast and color down a bit it gets better. unfortunatly I cannot tell you how to fix convergence, but I can think of some other possibilities. In this case the red/blue emmision of the crt is dying off and going into saturation when driven hard. To fix, replace with a new picture tube/crt. In some cases you can get a little more life out of that tube (with a watchable picture) by having the screen, focus, cathode bias, and drives slightly readjusted. It will take someone with experience in doing these adjustments on a weak tube to get it looking as good as possible. Given the construction of the cathodes (guns) in that crt, only a very low level crt reactivate should be tried on it. The hard rejuv most crt testers give is highly likley to completely destroy the cathode on that crt.
