Blank Tv Screen?

Question

Hi,

I have a Toshiba 43A9UM, for the past few days it shows no picture; the screen is completely blank(black) and there is no sound.

Any suggestions on what might be wrong?

Answer 1

Almost certainly the high-voltage power supply has a problem. There might be a blown fuze, but do NOT go inside the set unless you know what you're doing -- very high voltages are still present even when the set is turned off and unplugged.

Answer 2

Sounds simple, but first check the inputs, make sure everything is plugged in right, (if you have DVD player, check it and the cables on another TV). Also check the power outlet and make sure it's working okay (there's a joke about a person who's TV shut down every time they turned off the light in the room). If not...

I can’t find that model, but I assume it’s from 2001 or 2002. You’re hitting the “is it worth it to actually pay someone to fix this or is it time to say goodbye” timeframe. I think I agree with the hooded one, probably HV block or something like that, the thing is even if you fix that, the rest of the parts in your TV are still 5 years old and there’s no guaranty something else isn’t going to go out in a few months. (although CRT tech is pretty solid, less can go wrong that with the fancy schmancy sets coming out today)

Is it a 4x3 or a 16.9 screen, and is it at least 1080i resolution? If it’s 16x9 and capable of showing hi def, then maybe it’s worth fixing, or at least getting an estimate. If it’s a 4x3 screen and doesn’t have hi def, maybe it’s time to put it to pasture and get something new. 1080i was “IT” five years ago, 1080p is the thing now. I see 1080p as a plateau, sure there will be improvements, but they’ll be less and less noticeable.

Projection CRT's are stable, but subject to burn in and aren't "sexy" and flat like newer TV's. They'll soon be going the way of the cassette deck and VCR.

Anyway, hit Toshiba’s website for a phone # for a repair center if you want an estimate. Most companies will apply the estimate to the repair total (not that that really means anything)

Answer 3

This must be an overseas model I tried to find the schematic at Toshiba USA. It was not listed. I was trying to find out if this is a CRT driven projection or a LCD.

Answer 4

hi, your first mistake is you got an ALBA, i'm no longer going to conquer around the bush the following, ALBA are very very very adverse high quality products for my area, only about each difficulty they make is garbage and in easy words better healthful for the recycle bin, your second mistake is you purchased 2 ALBA's, i could propose you to attempt to get you money decrease back for both the TVs and use the money to get one respectable television. i imagine you need to truly have extreme words with the sales man or woman who bought you the TVs. desire you get all of it taken care of out asap and strong success.
