20 Most Recent Sharp Aquos LC-45GX6U 45 in. HD-Ready LCD Television Questions & Answers


Most likely the power supply board needs to be replaced. One or more of the capacitors is probably going bad.

If you don't know what you're doing, DON'T OPEN THE TV UP TO FIX IT, THERE ARE HAZARDOUS VOLTAGES ON THE POWER SUPPLY BOARD, EVEN WEEKS AFTER THE TV IS UNPLUGGED!
The capacitors in particular have the high voltage.

If you don't know how to do it yourself, find some local Electronic repair shops, get quotes, try to find reviews on the shops.

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.

I too have the same problem with the DC-DC board on the Sharp AVC. But I didn't spend the $134 for a replacement board (MCM or Newark).
Instead, I used the reflow technique by placing the circuit board in the oven for 7 minutes at 475F. You need to cover the plastic header connectors (about 7 of them) with foils to protect them from direct heat (and melt). Take the board out of the oven and give a little pressure on all the ICs while the board is hot. Let it cool down and voila! The TV is working again...

The sound can be muted or the sound is directed to a port that you don't use. The main board controls the sound, so if it's not muted or misdirected, then replace the main board.

The DC/DC converter went out on your set. When you take the top off of your AVC box look for a 4" X 5" circuit board mounted on the front left corner. I have seen these fail causing you white screen. Order the part from your local Sharp service center. Part # RDENCA089WJZZ

If you are using a Universal remote for this tv, then there are more than one correct codes, I would try another that is similar that will operate everything on your set. Sharps has many numbers you just have to find the one that works everything.

This television doesn't have lamps to change. Perhaps you need a Backlight Inverter/Inverter Board? If you aren't sure what exactly the television needs it would have to be evaluated. The television would have to be serviced by someone familiar with the boards/parts to ensure the actual problem is corrected if correction is possible.
