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?

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.

Turn tv on. green light solid display, no picture or sound


The flashing green light is likely indicative of a self-test failure, indicating the TV has detected some sort of internal fault. With no picture or sound, one strong suspect is the power supply. Flat-panel TV's have an internal DC power supply that converts the inbound AC current, and when these fail, or are unable to supply a minimum level of power to the set, it can behave as you describe, providing only enough power for the green light to illuminate.

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.
