Green screen and distorted picture sound is good but no picture

It's called Cyan and it's sound like you are having a problem on your D-board. Look for capacitors bulging out and replace first if not then order D-board

It can be that it has unstable power supply or the CPU/EPROM are getting scrambled by the noise and spike in the AC line, you may try better AC line conditioner to see if it will help.

Cheryl at a guess i would say that was why it was sold. It has an intermittant control board fault.

Now these often extend beyond just the one board ( there are 3) Opening the TV up is a risk to you as not only does it have scatter radiation type X but it is the HIGH TENSION area where severe burns and electrocution is the risk. Call a professional to fix it. We have people on here all the time trying to do this on the cheap, not many suceed as often they think that just swapping the boards out will fix it. Rare! Most times it ends up costing 3 times as much because they dont have the knowledge, essential tools or the skill to tune it properley and they end up fritzing the board again or blowing the expensive lamp.

take it to a shop and let them fix it right

I had the same problem. The repairman said the Convergence ICs were bad, located on the big aluminum heat sinks on the center board in the TV. He replaces both, and a couple of fuses (that look like resistors).

The tv worked fine for a couple of days then did exactly the same thing. They are coming back out to fix it next week. If there is anything different, I'll post an update.

Jar-Head, bad news, the picture tube has a mild short in the green cathode, tech can come out and try to restore it but it`s usually a futile attempt on sony tubes, sorry to be the bearer of bad news, BMW Rider

Our 37 inch Sanyo LCD HDTV has a problem with the picture distorted by being too wide. This has beenia problem for the duration since we bought the TV about three months ago. The PIX Shape button on he remote does not adjust this problem. We need help in solving the problem. Thank you.

Did you have color problems in past? Most of these sets have convergence problems. Amps goes out. But you should have seen some type of distortion from color, red,blue, green. If no color problems then maybe vertical ouput out or horizontal output bad.
