Question about Toshiba 40H80 40" Rear Projection Television

1 Answer

40H80 Toshiba Rear Projection TV

The Problem

1. The first couple problem events - the picture sort of warped really weird then it went back to normal. This was over a few days.

2. About a week or so after the first problem events the picture started going to a sort of rolling lines flashing deal after a few minutes after turning on the TV. After cooling a bit it would refresh and do the same thing again. Sometimes it would go back to normal.

3. The TV still usually works for a few minutes but it has gotton worse in that it just goes blank after some flashing and stays blacked out until the next time we turn it on later. Also, now the sound even goes off with the picture most of the time.

I've turned this problem in before once with a little less description. The reply was a little less than I had hoped for.

Went blank sound and picture went off will not turn off with remote or tv button. I have to unplug it to turn it off. when i first turned it back on it was just blue screen now still having to unplug it...


Most LCD tv's having a lot of bad caps in the power supply ,that makes for really weird things happen, since they work like a computer during boot. For that 2-3 second "boot" the processor in the set checks for a combination of things and if those caps go bad in the supply the set will show a wide variety of symptoms.
Usually the set won't start for a minute or two and sometimes longer, after that comes some weird things like lines and what not and the set finally just won't come on period.
I could write a book about how simple fix like changing a few caps causes all kinds of phenomena..lol

Pink and Black in natural light


It sounds like the light sensor on the camera is malfunctioning. Try cleaning the sensor. If the senor doesn't work at all it will not be able to tell when the camera is operationg in bright light. Kind of like having your eyes dialated and walking outside on a sunny day.

COLOUR PROBLEMS


Greetings!

This sounds like a degaussing (named after 19th century scientist Carl Friedrich Gauss) problem. This usually occurs one of several ways:

1. The TV fell down and went "boom".
2. Junior held a magnet up to the screen when you weren't looking.
3. There is a large, unshielded speaker near the set.
4. The TV was rotated in relation to the North/South magnetic poles of the Earth while it was running (yes, really).

All televisions have a degaussing coil built into them which is activated momentarily every time you turn on your TV. This typically will cure all minor anomolies over the course of a few days. However for a severe one like you have, it will probably require a trip to your friendly repair shop. I, personally, do not charge anyone to perform this service because it takes, literally, 5-10 seconds to degauss a TV. I simply ask them to remember me next time they go to buy a new TV or need service work. I can't say that your technician will do the same.

In the case of the first instance of the TV falling down and going "boom". If it fell with enough force to warp the shadow mask built into the picture tube, then all of the above information means nothing. The set will require a picture tube replacement to cure the problem.

Hope this helps,
Rob

Picture flips from color to black and white continuously


I believe your set has a loose conection that needs to be resoldered ,every time you hit it reacts and that is good,you need to use a wooden or rubber handle to tap in the main board,around the tuner and in different areas until it reacts,be attentive when it does so you can flip the board and resoldered the area that made it react,once the problem is corrected you need to resoldered any other overheated areas and there should be a few in your set,check the grounds in the tuner(where the coax goes in the inside,is a silver box),the horizontal driver transformer and output transformer.Be careful while you do this and stay away from the thick red wire going to the back of the picture tube specially when the set is on. Let Us know how it goes or if you need more information.
