I noticed lately the picture had been shaking but just last night when I turned it on, the picture was good for about 5 minutes and then it went away leaving a small rainbow of color across the middle of the screen. I have perfect sound and sometimes the picture will reappear for a few minutes and it's gone again. Can you help?
His is the vertical circuit going bad. you willl need a repairman for this. unless you can solder?
a cost of repair might range around 400.00
good luck :)

Re: Sound but no picture
Was it shaking up and down or from side to side?? It could be a verticale sweep problem as thats the most common fault in this set and another one is the horizontal output goes bad because of a defective high voltage transformer. It could also have bad capacitors on the secondary side of the flyback switching supply. This is a hard call with out seeing a schematic. Good Luck.

One thing I've done, which might be too late for is submerge my electronic device (cell phone, remote controls, etc) in 99% rubbing alcohol. The logic behind it is, alcohol is non conductive so it wont create shorts, combines with water and evaporates faster than water.
I think at this point your best option is to find something to draw the moisture out of the camera. You need to remove the battery until this process is done as well. Rice (dry uncooked) does a decent job of absorbing moisture. Whatever the case is, you will have to get all the optics cleaned after its dried out.
Yes it's the lamp. I had the same issue in the middle of last year. I bought the whole bulb assembly for $220 Canadian. I'm confident that it was through Samsung USA. I did find a site that said you could "save money" by buying the bulb only, but their price was the same for the bulb alone, as I paid for the whole assembly. It took about 15 minutes to get the bad one out, and put the good one in. Now I need to find out how to adjust the mirror angle... Good luck
It sounds to me that the Main board is causing the problem. But I would get in touch with Toshiba for a warranty repair. It has a one year parts and labor warranty. It makes it a lot cheaper for the pocket.
Good Luck,

check your ribbon connections coming from power supply board there is 2 of them it will be the second one,theses ribbions connect to signal board.Sometimes causing set not to come on.
Sounds like horizonal output transistor could be over heating. There could be other problems. But I would start there. You can find the part number on the schematic inside the set. If you change it yourself don't forget to use the included insulater. Part should cost between 15 & 20 dollars. You will need make & model # of set at electronic parts store.
Diagrahm inside set will show you location of transistor.
I have the same problem. The only way to get the TV to come on is to unplug it, but once you get it back on it turns itself off again in a few minutes.
With your remote, go into the menu, find the audio setup and click off the SAP. Thats the Second Audio Program. Some Broadcasters send a second lanquage along with the regular audio. Someone must have been looking around or playing with the remote and turned on the SAP.. Good Luck
