Question about Toshiba 42H81 42" Rear Projection Television
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).
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.
