Question about Toshiba 42H82 42" Rear Projection HDTV-Ready Television

1 Answer

42H82 Picture is ALL GREEN

Really simple problem. Picture is COMPLETELY GREEN. Turn on the TV and you see nothing but green. Determined it is NOT a gun problem. Been looking at the hyper board and suspect the problem is there. Any solutions?

Re: 42H82 Picture is ALL GREEN

If the picture is all green and does not shutdown then is probably not the tube and you need to check the green output transistor witch is ussually located in the crt board in the neck of the green tube,you also have an IC that gives the colors then you have a driver and finally the output,(IC and driver rarely go bad but is possible),when you pull the board out of the tube make sure it comes out easy,do not twist the board because it might brake the pins in the tube(gun) and then we will have big problems, many times they secure the board to the tube with silicone and it needs to be removed or cut before the board will come out.Each gun has an output and the defective one should be replaced with an exact replacement.Check also the conections in the green crt board.Let us know if you need more information.

Tv comes on for 10 seconds then fades to a green tint then turns completely green for a few seconds than turns off

Symptom shows tv got problem with green picture tube that need to be replaced.
Rear projection tv has 3 picture tubes, red-green-blue to make color picture.
Since its an old model so spare parts would hardly be available and local tv repair shop will help you to arrange required part, if they can.

you need a green CRT thats whay you have the white kind of concave lines with the green screen. You can try adjusting the green screen control but you need anew CRT ( tube) the speaker cover has two plastic plugs that get removed on the lower edge os the grille which covers the two screws that hold the grille on. If you need more assistancr or where to get a green CRT let me know as I have a link that has some green and red Tubes for your model.

Toshiba 42H82 RPTV: Sound but no picture

It sounds like the 200v supply to the crt's is missing. this is the source for driving the tubes, other than the high voltage generated by the flyback transformer. If the set got really bright gray with wome white lines that are kinda on a diagonal, this is generally the cause. the source for this voltage is a diode on the secondary of the flyback transformer.
