Question about Toshiba 57H81 57" Rear Projection Television

1 Answer

Television requies a new signal board.

The television is a 2003 model. Up until last week it worked fine; great picture and sound. At the beginning the picture was scrambled (diagonal lines on a forty-five degree angle to the left. After the television warmed up, the picture got better but not to where it should be. When I took the cover off the back, the black ground wire attaching to the coax junction box was loose. When I moved the wire the vertical lines dissappeared and horizontal lines appeared about three quarters of the way up the screen from the bottom. Anyways I took the TV to the store where I bought it to have it scoped. The result was that I need a "signal board replaced" part number 23546746. When the store tried to order the part, Toshiba said that the part was obsolete. Know I'm surfing the net trying to find that part so far with no luck. If I cannot find the part, I do not think I'll ever recommend Toshiba to anyone. It is sad to pay $5800.00 for a TV that doesn't even last five years and that you can't even get parts to fix it. If their is anything that you can recommend or a place to buy the part I would very greatful.

I have the model D52W19. I have two TVs in the house one works fine and this RCA model is a problem. The set usually turns on OK, then it begins to snap and pop. The screen will go black for either a few...

the small signal board would be suspect on that model. Depending on the bar code number which is on the small signal boards sticker you may find a replacement board at for your model.

Audio is processed on the small signal board. It may be the audio output or you may need to replace the small signal board if you have noticed the sett shutting off evry once in a while. The small signal board having problems is very famous in RCA ITC222 and the ITC222A series.

Problem after replacing convergence board

Yes, you do need to set up the convergence in order to get the picture geometry correct. the antenna and maybe some other settings will need to be restored through the appropriate user interface screens. You will need your owners manual for a guide.

Tv lost color

Your problem most likely is on the signal board is my guess. If your not a technician it would be in your best interest to have him check L2C60 on the signal board.

MY Samsung HCN4226W have perfect sound but no picture

I had the same experience with my set. I noticed there were 2 new cables attached to the new board and looking carefully noticed the connectors were different from the old. The new connector fit perfectly into the new board but wasnt the same as the old. I replaced the old cable with the new and the TV remained bad. I then flipped the connector to the main circuit board (bottom left) and the new board worked fine. I know nothing about Tv repair, but this new cable seems to be a universal connector in which the contacts are open on 2 sides...allowing them to be flipped if necessary. Now if I could get that solid line out of the display I'd be set!
