Tn61x81 My screen has a horizontal black arcing line across the top and bottom of he screen. The bottom is worse. It almost covers 1/2 the screen. I changed the convergence chips with no luck.

Also, I have tried to get a service manual for this tv and cannot find one, any suggestions on how to fix this problem would be greatly appreciated.

Convergence issue I apologize for not having the exact model number. I have what seems to be the typical convergence issue with my TV. I have pulled out the board and tried resoldering the 2 main chips but the problem came back. I would like to purchase chips for this but I want to make sure I order the correct ones for the 42" set. Do you know which chips that I need?

55809 convergence Ok, so, I was having convergence problems with my 55809, and would concede to kick the side of it to bump the convergence back into alignment. Now the TV won't turn on period. The green power light comes on, but after a few seconds it goes out. I've been hitting the net hard on info, and it all seems to come down to a convergence problem with a couple of fuses and maybe some chips. Having said that, I looked up parts for repairing my TV and found a kit at tvrepairkits.com tha

TV has worked just great since purchased in 04. Sat down this morning, grabbed the remote and nothing happened. I replaced the batteries in the remote, tried it again and nothing. I tried the manual power button on the front of the TV and still nothing. I tested the power outlet and it works fine. As I plug the TV in, I hear a soft click as if it is trying to power on but still nothing happens. I pushed the reset and it makes a soft click but still no picture or sound.

My HP LC4276N TV is 27 months old. A few days ago, the sound just ceased working. Of course, I checked the settings to ensure that "mute" was not activated and that the setting for speakers was "on". I then also tried connecting auxiliary speakers, but to no avail. Could this have been caused by a blown fuse? A bad capacitor? Or is there another likely cause? I would love any detail on how to check any of these potential problems, or any suggestions for repair. (I have no experience in t

I have a Sharp LS-26SB24U that has a white screen when turned on. I tested main fuse and F404 fuse both were good. I tested power going from F404 to ground and it was 13v on both sides. I guess my next step is to see if the T-con board is getting power but I'm not sure how. I tried following a white line that said power and along is was a hole and I went from there to ground but got nothing. Any help would be greatly appreciated.

I live in France and have bought a Techwood GDV 9167 HDU but, of course the manual is not in English. I have tried, for several hours, to set the machine up but I have now come to the conclusion that a) my French isn't as good as I thought and b) neither is my techinal know-how. I am therefore looking for a manual in English. Any help you can offer would be very welcome! Regards, Phil Watson
