Sharp LC 37GB5U

I can get no sound out of the TV- I have checked with another tv at the site and the sound is fine. Is there some switch to turn on the speakers? I have read the manual, checked the menu twice with no results. I hear a fant click when powered up I have gone thru the menu and can not seem to locate it if it exists. Seems as if they are not plugged in is that possible I am seeking help before I haul it in for a fix thank R

    I have a sharp aquos 27 inch flat screen LCD, and the sound goes in and out...one minute we have sound and then it just goes out.  This has been happening since the tv was brand new.  My husband was convinced it was our cable box, but we have confirmed that it is definitely the t.v.  and were wondering if there is anything that we could do to fix the problem before taking it in for service????

Just go back over it patiently double checking as you go reading it thru. Make sure you have connected it right. You will not get sound if it is connected wrong.

I think these are the ones that you need to replace the heatsink goop with the silicone pad and the amp chip.

I have a LC-37GB5u, the unit comes on for one second then off then the OPC red LED flashes two times per second. I have replaced the 82uf caps and all four MosFETs. with no change.


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty.

TURN TV ON JUST PLAIN SCREEN (NO IMAGE), THEN HEAR A CLICK & TV TURNS ITSELF OFF- THEN ON AGAIN... CHANGED BATTERIES IN REMOTE & TRIED TO TURN TV ON DIRECTLY FROM TOP... NOTHING WORK. THIS IS A...


Do you see the backlight ever coming to the screen?

You will want to open the cover, disconnect the backlight inverter and try again to see if it will stay on even without an image.

If it does it's the inverter.

if it still shuts it's most likely (not guaranteed) either the power board itself or the main board.

A good tech should be able to test the power board independantly fairly quickly.
