Re: toshiba 50a50

You have a problem in the deflection circuitry, thats why youre not getting any picture. Probalya blown line coil or transistor due to the surge. You may want to invest in aservice manual for your set If you have soldering skills you shouldbe able to track down the prblem and repair this set. You can get the manual for your set at the following link for 10.99 and they will email it to you if you requestfor them to do that for you. Here is the link. Hope this helps. let me know if I can help you further.

My Toshiba 50 A 50 rear projection has great sound but no picture. Can you help tell me if I need a fuse or bulb?

This TV does not use a bulb. It is a Picture tube type set.
*No picture but there is a dim background. Menu works.
This is caused by a bad signal. Perhaps the video cable is bad if you use a cable box. The HDMI cable may not be working right. Try a new cable.
*No picture, no menu
This could be caused by a failure in the part that draws the picture up and down (The vertical). Can also be the side to side (Horizontal) or a high voltage problem. The last usually kills the sound as well so its not as likely.
If the cable does not fix it, you will likely need a technician.

It sounds like you are in Closed Caption Text Mode. You should be able to get into the main menue with the Toshiba remote, get to the close caption Icon and turn off Close Caption. This should take care of it.
Hope this helps,
