This might help. 1. There are two screw holes on the front of the unit near the edge of each side right next to the speaker grill. It is covered by a plastic cover that has two tabs holding it in. Carefully pry them out with your flat head screwdriver. Do not apply too much pressure or you can break the tabs off. Once the covers are removed, unscrew the two screws with a Philips screwdriver.

2. To remove the cover, pull from the bottom of the front case and rotate towards you. Once you rotate it out, the top will disconnect and come loose. Do not pull it off, as there are cords attached. Loosen the cables attached with the twist ties and set the front cover to the left side.

3. With the speaker grill and cover removed, you now need to remove the wood panel to expose the inner electronics on your Sony HD TV. To do this, remove the four Philips head screws from the panel. Then, pulling from the right, rotate the panel off and the electronics will be exposed.

4. The little black box towards the front of the unit at the bottom is where we you will concentrate your time as it is the control for the voltage & convergence adjustment.

5. When focused in on the controls, you want to concentrate on the bottom row for the voltage / ray gun projection adjustment (you will be adjsuting the voltage to the CRT Cathode Ray Tube). The colors are not labeled but are from left to right blue, green, and red. If the screen is all blue or has predominat blue lines then blue needs to be adjusted. Choose the one that needs to be adjusted and turn ever so slightly with your Philips screwdriver to remove the lines or change the picture. Do not turn to quickly or abruptly or you could possibly damage your TV by varying the voltage too quickly.

This is hitting a nerve, I had the same tv, and I had it fixed by Brandsmart twice in 1 year. Finally they gave me a credit for the full price, and I got an LCD. But before you throw something at me, it is one of your color guns starting to go on you. there are only 3 on those sets, if you have a warantee extented one, get it fixed before it comes off warantee, I had a 5 yr extended, they don't last longer than that "the projection Tv's", the newer ones are better but yours has to be at least 5 years old correct? I went through 2 projection tv's in 10 yrs, so I have to conclude that they don't go far past that time frame. The last time they fixed the Sony I put it on Craigs list for $650 and got rid of it before it went out again. Sorry I don't have better news for you, but to start paying good money "in the $3 to $400,00 range to fix it is a bad idea, as the other parts are old and will start a domino effect on you. And if 2 guns are gone which was what they found with mine, it would have cost more than I paid for the set new, to repair it.

The red and other primary color correction must have to be done from the settings of the TV.the incorrect values in that have caused this problem.try to reset the tv so that the original default settings will come and take place .this may also cause, due to a damage in the capacitor.try to check it also .thank you.merry christmas

Samsung DLP Facial Colors off after changing color wheel


Do you mean that red and blue are reversed? If so, you may need to remove a jumper, see end of linked article. Pinkish-yellow or orange sounds like a good description of skin tone, but perhaps too intense. If the color is too intense, can you just lower the color level with the color control? Or can you just change the tint with the tint control? Otherwise, see http://www.jangro.com/electronics/samsung-dlp-replace-color-wheel/ including the comments at the end.

I had this problem and at the same time I was getting blue tint. When the blue got darker, this would happen, Adjusted the voltage on the guns (3 screws in the front - lower panel off) and the blue went away and it stopped turning off. But later, it would start all over again. Same procedure, same fix.
