To correctly repair your tv all three CRT's (picture tubes) would need to be replaced as instructed by SONY service bulletins. Many years ago SONY wanted a better brighter picture and began making some CRT's differently and "better" . But saddley they did not do enough testing . After a few years they realised the mistake and they paid dearly for it. Unfortunatly enough time has passed that the $750.00 or more cost or repair can only come of the consumers pocket . They are good solid tv's when the CRT's get replaced with Panasonic picture tubes.
Sometimes screen control adjustments can be done to make the TV work for now but usually a flicker in color remains and it most likely wil get bad again
Hope this explains it for you.

I had the same problem with mine. After A LOT of research, I never found a good solution, except that strange things seem to happen when TVs get too hot. On my Sony, there is a solid panel behind the cloth-covered lower front panel. I removed the solid panel and drilled a series of holes in it to allow more air circulation around the projection tubes. This seems to have corrected the problem, at least for the time being.

Today my 55" vizio screen popped and then turned red. I unpluged and restarted everything and now the audio is on, the chanels change, but the screen is completely read. some images are readable.


If this is a VO47LFHDTV20A TV set, the problem is most likely your LVDS(cable from the main board to the t-con)cable is faulty. When you turn the set on, do you have a red screen instead of the standard blue screen? Do you also have red tints on all images on all inputs? If this is the case, your LVDS cable is bad. If you are comfortable opening up your set, track down where the LVDS cable goes into the t-con board. Turn on the set, and wiggle the cable, if the red tinting goes away, you will need a LVDS cable, about $24 part.

Your Red CRT may be on its way out. Try turning down the G2 screen control on the red CRT just a little. That should help for now. A new red tube wil be a reality in the future.
