Re: Toshiba 52hm84

It's either signal board or light engine and unless you're really pretty good at electronics neither one is something you should tackle. I do have the service manual for this unit and I would be glad to send it.. Just drop me an email and make sure you include the model number as well as what it is you need.. I get almost 650 emails a day so it's really hard to remember who's email goes with what problem. :) Good Luck Bill

Spots all over screen

We will presume you have a DLP set that uses a lamp of some sort(no brand or model indicated here).

spots or dead pixels are usually a damaged optical light engine--there are ones where more and more appear.

A faint possible reason is dust is inside the optical light engine--seen it a few times but the spots are usually golf ball in size----high pressure air applied to the vents in the engine with set on in a dark room usually clears that up.

Dark spots on screen on DLP when screen is white

What size are the spots?
If they are 1 pixel in size you have stuck DLP mirrors.
If they are larger not symmetrical then it's most likely dust blobs in the optics near the focal point (on the DLP chip glass window)

My Toshiba 52HM84 blows bulbs

Ensure that you don't handle the bulb with bare fingers. wipe the bulb with meths and hold the buld with a lint free cloth when you're putting it in. If it's still blowing it's probably over heating so check the fan

Screen remaining black after the TV is turned on

Some newer sets appear that way when there is NO signal to the set. That and my Sony looks like that when the bulb is burned out.

TV has sound but no picture

It is possible one of the internal fuses blew out.
It could be a bad horizontal outut transistor.
It could be a bad secondary of the power supply went bad
And many other things.
If it's just a fuse, it won't cost much, but a lot of them do not look like you would expect a fuse to look like.It might be a little yellow, green, or gray rectangualar box shaped part. :D

Mitsubishi VS-60603 60 in pink spot

I have seen this before, and I can only describe it as a flaking of the phosphorus coating in one of the picture tubes. If you can, remove the back such that you can take a flashlight and look down into the 3 picture tubes. If you see any flaking or dark spots in the phosphor, there will be a spot on the screen missing that color. Unfortunately, this is not repairable, as all 3 tubes would need to be replaced (like replacing all 4 car tires when one is completely bald) and that would cost more than a new TV.

Screen spot

Since you have a black spot,you need to look at the mirror or inside screen. If it were a certain color, like purple or yellow, for instance, I would suggest a lens or picture tube, but, since it is black in one spot, I would suspect debris in those areas.
