Wavy White and Grey lines then nothing

The Flyback transformer needs to be replaced on the Deflection Board. It has the big red wire coming out of it going to the picture tube. Becareful with that. Some of them hold a nasty charge waiting to bite someone. Wont kill ya, but it hurts.

Tv comes on just the sound about three seconds later tv shuts off

I have the same issue with mine and have a solution that sometimes works. I had a repair guy come to check it out and he powered off the TV so that the red light was no longer blinking, then he unplugged the TV for about 30 seconds or so and then plugged it back in. He then turned on the TV and it worked. He said it would cost about $400 to fix the issue (some circuit or something). I have since expeerienced the on/off problem (due to power outage) and now I cannot get the TV to work. But at least give this solution a try and please post to let me know if it worked or not. Good luck!

If the set runs at all, your flyback and output transistor are good. If the set shuts down after a few seconds and the sides are wavy, it usually means that the main B+ in your power supply is too high and not regulating properly. I do not know what kind of power supply that model uses, but if has an old-style STR regulator (like the STR30130) then it is probably shorted, and if the set uses a switching power supply then look for an open or leaky electrolytic cap on the primary side. If the power supply is working correctly and the set shuts down, check for an open safety cap (the large 1.6 - 2Kv cap connected to the collector of the horizontal output transistor).

Screen white tinted, horiz lines, then shuts off

Not acutally a solution. We are having this EXACT same problem; it started this week. Let us know what you are having done. I've called Toshiba and service reps but they are all quoting a price which is almost half the value of the tv. Have you been able to fix it? We are pretty upset since the 2year warranty recently expired. Obviously, it seems that others are having this problem as well. Email us:

Red lines across screen

it sounds like a b+ cap going bad and is intermittant that feeds the the video drivers on the crt pcb or the crt is shorting. I have seen intermittant shorts in crt before.
