    Add a CommentI am in the military and deployed overseas, so parts are limited. But we are a bit tech savy. We have a Electrical Engineer in the office and I am an electrican working on my degree in Electronics Engineering Tech. We have a Sharp LC-52D64U and it seems to have a power supply problem. We get the following code: Power>flash then Power&OCP>flash then repeats. I didn't find any bulging Caps. Will the problem be on the main Power Supply or the Inverter board in the middle of the back of the TV? Thanks!!

    Could have bad CPU data firmware problems to the main signal Tuner board,but Sharp Corp.never admit this and never have upgraded firmware software for the tv series known as Aquas from 40 to 52 inches screen.

Horizontal lines showing behind tv menu


Hello,
Normally the menu is generated in the LCD Control Unit. If your menu looks good, but the defect is behind the menu, I would suspect the Main PCB. Good luck to you. Part# is DUNTKD934FM01-V1.

Thin blue line


I am a Sharp Servicing Technician. You posted this before. Ive got the same model TV as you do LC46D62U. I think the line you are experiencing is simply the broadcast. I notice it on some HD shows that broadcast the side bars. (Always on the Ellen Degeneres Show). Ive taken some picture.

1) Here's the line on the left that i experience

2) Later on in the broadcast, it goes away.

One way to check if its a TV problem or not. When the line shows up again, hit the MENU button on the remote. If the line appears to be "behind" the menu, then it is simply the broadcast.

If the line appears to be "on top" of the menu or shows right through the menu, then it is a TV problem.

Im thinking the reason it takes hours for hte line to appear is because it only shows up on certain shows or certain HD broadcasts.

Sharp Aquos 46 In TV Problems:


Sharp list no issues or service tips for this model but I am sure most freeze ups are and issue of weak cable signals or defective cable receivers. If this has truly been elimnated the main digital pcb in the TV could be issue or more likely the TV may need the latest software upgrade. This is most likely only able to be facilitated by a Sharp auth. service center.
