Question about Toshiba 42H81 42" Rear Projection Television

1 Answer

Flickering on black screen or dark areas of a screen

I have a toshiba 42H81 that is about 4 years old. We recently moved and since I have hooked it up, it now flickers. It is most noticable on any black screen. It is getting worse. I thought it might be an inuput or cable, but it does it on all of the inputs. It is still watchable, but especially on HD the flickering is getting more noticable. The flickering resembles a light flashing over the entire screen. I have adjusted the convergence and I have tried unplugging (which Toshiba suggested).

Re: Flickering on black screen or dark areas of a screen

The moving might have created a loose conection,the sets age tell me there are possible other overheated areas that need to be resoldered to prevent other symptoms,If you are familiar with tv service you can check the conections in the output transformer area,he is responsible for generating the high voltage that lights up the 3 picture tubes,before the Hight volatege gets to the pix tubes there is a High volage distribution box that separetes the voltage for each tube,check it and make sure is not degraded,you need to be very careful when dealing with these parts,there is a lot of volatge in that areas,If you are not familiar with tv service be safe and call for assistance froma servicer.

The easiest way I have found to set the screen controls is to tune into an old black and white show, turn the green up until you see retrace then slowly turn it down until it just dissapears then adjust the blue and red for a true black and white picture.

Flickering - Toshiba 62HMX84

it could be as simple as the tv feeding back on itself in a dark room.
it is adjusting the light level because of what it sees ambient in the room.
turn on a light near the tv and see if it stays constant now.

Toshiba 51H83 51 in. Rear Projection pisture issue

I have a wild guess. I have the same tv and channel 72 is the proper channel to watch tv on. I don't know why, but maybe try channel 72 instead of the usual channel 3. Good luck, maybe a quick fix, maybe not!
