Plasmas are like tube TV's(CRT). Once the plasma tube breaks, air gets in, plasma gas gets out. And that's it. They are an enclosed vacuum picture tube. I don't know why people buy plasma. The newer LED have a much better picture. Rich people who swear by plasma, are ridiculous in my opinion. Again, if plasma tube breaks, thats it. Any wrong jarring can break a plasma tube.

Hello
Check its speaker first. This is a common faut to this free TV. If it is OK, replace the audio output IC. OK.

Projection TV sets have two very common problems listed below.

Problem #1) Convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

thanks doctor video leading edge electronics

Is your picture somewhat weak ? This could be a problem with the picture tube . One thing you can try is to turn the screen control up just alittle at a time to see if the picture comes in . Once it does turn off and back on to see it it comes back on again . It might take 10 to 20 seconds but if it does your picture tube is weak . The control is on the flyback transformer it is the bottom control . Or it may be on the crt board on the picture tube . One thing to check once the picture comes is the video input . If you go to this mode and see faint white lines might want to try to turn the control down a little more to see if you can get them out and the picture stays on , if not thats how going to have to watch it . These picture tubes are expensive $500.00 to 700.00 depending on which one you have . One possible other thing if you tell me the picture was a great picture almost like brand new check the horizontal section for a loose connection as this will cause this problem . Don't get shocked and be carefull , Good luck

This is a common failure mode (which I now share), and has nothing to do with the picture tube or surge protection. From the forums I have searched to-date, it appears to be a failed component in the flyback circuitry, but Sony will not admit to an inherent defect. If anyone has ACTUALLY FIXED this problem, please post a reply. Guessing won't help anyone. Thanks.
