Question about Toshiba TP50H50 50" Rear Projection Television

1 Answer

Scrambled Picture/Snow Screen, has sound, can play DVDs through colorstream

Have a Toshiba TP50H50 that just started giving me problems. Its about 7yrs old and wanted to get some suggestions and possibly repair myself prior to going to a shop or purchasing a new TV. The picture is "snow" when trying to watch cable but has sound. I can put in color stream mode and the picture is perfect when playing DVDs. When I go to the menu in TV mode, menu is perfect but I just get "snow" in TV mode for cable. Any suggestions.

No picture, no sound, but has power light...any suggestions? thx in advance

Do this first:

1: Check the antenna/cable connections.

2: Press the TV/VIDEO on the remote control or the TV to view a signal coming from another device connected to your TV, such as a VCR or
video disc player. You can select ANT 1,
VIDEO 1, VIDEO 2, VIDEO 3, ColorStream HD1, ColorStream HD2, or ANT 2 depending on which input jacks are used for connecting the devices.

*Be sure you have the right source to view video.

Try the above and post back before I can say there is a problem with your unit. If you have the user manual it's a good time to get it out. If you don't have it let me know and I will give you a link to obtain it. Good luck!!

Convergence will not work

You need to replace the convergance IC's it probably has (2) STK392-110,but I replace them with STK392-150.If there are still issues check resisters close to heat sink,also check the pico fuses.This isn't a do it yourself job unless youv'e been around a hot iron and can remove solder easily.

Other inputs not working on rear projection toshiba

check for progressive scan and interlaced setting also verify if you have component hook up that it auto maticall chooses your resolution because if your tv is waiting for 1080i and you send 1080p it will not always work and if it expects 1080i and you send it 480i(s-video or rca connection) it may not automatically flip

Hi There!

I am not familiar with this model,however if there are no screws or clips on the inside or side panels, the front would be the place to start. usually right at the bottom front are screws to remove the bottom front panel first. Then the rest will be exposed. Work your way from the bottom up. The screen itself will be last and normally hooks over the top frame. Good Luck, JUS004

Scrambling for first 15 mins

That is the exact problem I am currently having with my toshiba 50 in. I did some reading and it sounds like there is a temperature drift across one of the capacitors on the board and it takes longer and longer to warm up. Havent fixed it yet...

Toshiba TP 50H50 Blank Screen

IT sounds like you lost your high voltage going to the picture tubes. This could be due either to part of the main power supply going out due to a defective capicator or semiconductor, or something more serious in the High voltage distribution network. With the age of the set, I would be most inclined to replace it with a new HDTV, and Toshiba still are pretty reliable sets. If you can afford it, a Sony KDS-55A20 puts out a beautiful picture for around $2300.
