SOURCE: My TV Sharp 26 SB1 LCD PBS channel breaks up

Do any other OTA channels break up on this TV? Look through your setup options menu for a TV reset (memory or restore default or a similar command) . Do the reset and exit the menus (save the action on most TVs); then return and rescan the OTA channels.

On a different brand of TV this worked. The channel had broken up for several weeks; the reset was used when the channel finally became totally corrupted (no video on one sub-channel, no audio on the other).

Some tuners need a stronger signal to be stable; you may need an amplifier on your antenna.

I hope one of these ideas helps.

How do I replace a broken circuit board on a Sharp LC-60E78UN TV?

You can either remove the power supply and check and replace caps and most likely the transformer (pop sound). Or a replacement can be found on eBay, amazon, etc... One model TV can have numerous diff power supply models from revisions and improvements. If you replace the board make sure you look match serial numbers on board to the new board. The back of the TV will come off very easy. Lay TV face down on a flat surface(making sure nothing is touching the LCD) remove screws. (Make sure cable coax slides free, some have a retainer but to remove) once the back is off the layout should be so simple, you should have no problem identifying parts.

Get screw thread size & length for lc26Ga5u

Which screws are you talking about? My 26" Sharp uses metric screws for everything but there are several different sizes. If you're looking at the wall mount screws, find the metric screw that will thread easily by hand and limit the length to about 1" long. (Check Lowes or home depot in the hardware section.)

There is a constant whining or ringing sound even when muted or viewing DVDs. It is a Sharp LC-42D62U. What might cause this?

Electrical interference inside of the Television is the culprit here!

CRT and old Televisions used to produce this sound.

I would contact Sharp concerning this, since LCD's do not usually make this sound. You could get a warranty replacement for the television since there seems to be a malfunctioning part.

Hope this helped!

Image goes to black on Sharp flatscreen.

An LCD unit? Sounds like the backlight is failing. When it goes black next time, use a strong light next to the screen and look for a faint image on the screen....

If it is the backlight, its a service shop issue.

Sharp lc-26dv12u about 2years old. All of a sudden

Sounds like the Main mother board is the problem. When the processor chip overheats, the programming information passing through the chip slows down. Most cases, replacing the main mother board will fix the problem.

Sharp LC 37 D6U

That popping noise means the silicon grease underneath the audio ic has melted and is shorting the audio. This is unfortunately a design flaw by sharp. To fix the problem, you'd have to disassemble the entire TV and clean off the melted residue off of the AV Board and replace it with a new Sharp Heat Insulation Pad. Its a pretty difficult job, I suggest calling your local Sharp authorized service center to fix that for you.
