I have an older Toshiba TP50H50 projection TV. I bought it back in 1998, and figured it would need maintenance soon. Just recently, the screen went dark with the sound still working. I figured it would be the bulb burnt out. Does this sound about right? Also, do you think it would be worth it to fix this issue or just replace the set? Thanks.

Re: 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.

Checked four different distributors and as far as I can tell none of the screens for this television are available. If you are handy with a tape measure and have a screen bigger than yours from another set you can cut it down to fit. Just measure from the corners to find the center then measure out to the dimensions you need to replace the old one.
Try this link, leave them an email but you will need to measure your screen size top to bottom and side to side just the visible screen area then leave them a email at the site they will get back to you soon. http://servicemanuals.vstore.ca/
the only fast solution is to go to an authorized TOSHIBA dealer repair shop and have it order it , warning the screen is expensive as I found out when I needed one too ( i own a 55" TOSHIBA ) it could cost around $200.00 up to $400.00. hope this info helps
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
On alot of these Toshiba TV sets, there is a fuse called F860 that will blow and the light will flash because of bad solder connections on C 810, and C 809, on the negitave terminal. I have seen many of these boards condemed by non-authorized Toshiba repair shops. Good Luck
