    I have a red power light but after about 30secs it turns to a red blinking light.
    I cannot get any further so no TV. I have tried the system reset button and while I hear the slight click of reset, the red blinking light problem is still there.
    My model is SHARP AQUOS LC-26GA4X
    Thank you

    I have a Sharp aquos LC-37HV4U. Out of nowhere I can't get POWER. The display status indicator on the tv is blinking red. The AVC status indicator is just red. Turned off power for an hour and re-set. Still Nothing.
    I'm trying to see if there is a simple solution before I spend $170 for a company just to pick it up. Anyone???
    Thanks

SHARP AQUOS IS GARBAGE.
I had the same problem. 2 months out of warranty and the tv power supply is dead. The repair will cost as much as a new tv.

To get the accurate values to all the pins and test points, you have to download the repair manual to this set by internet. If you wish to get some details about the voltage charts, check the site linked here. http://electronicshelponline.blogspot.com/ Pull up previous posts there, either by its left side bar, or view it in Timeslide option.

Sharp AQUOS LC-32D44U 32 in. LCD TV red light blink once


I see so many here with no sound/nopicture issues:

ISSUES:

1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.5_27_2012_5_31_29_pm.jpg5_27_2012_5_31_52_pm.jpg

No sound and screen sharp tv 20"


Hi,

Would you be able to be more specific about the behavior of the set, for example does anything happen at all when powered? ie does the standby light come on? does it try to turn on and then go back to standby? or is the set totally dead?

Thanks

Hi I have an LG LCD tv and this morning it just went dead, as if there is no power getting to it at all. The electric supply is ok Regards BMcD


If it is completely dead (no standby light, flashing LED blinks), the power supply failed. Replace the Power Supply board to fix.
