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

Bryansled is 100% correct. I had the same problem, and was told by the repair shop it would cost about $500 and it was probably better to buy a new TV set. I was skeptical at first because the part costs about 150 bucks. That's a lot of money if it doesn't work. But I figured WTF, just try it. Easy to install and it worked right away. Bryansled, I can't thank you enough.

Sharp Aquos LC45GX6U & TU-GD10U. The unit doesn't power up, and has a red blinking light from the moment you plug it in. The unit works fine in service mode.


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 have a Sharp LC-45GX6U Display & TU-GD10U-T AVC box, and only get a white screen on the display. I've been told that I can bypass the AVC box altogether, and just go to the dispay via HDMI. What...


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 screen and the module both are showing red lights . The screen will not show a picture and I have tried to reset. Any options?


Press the VOL+ and Channel - button on the set and than the power button while holding the two buttons.
If the set starts then the fault is the error counter wich must be reset to 0. Max is 5 faults,if a sixth error is measured the set stops.

No AVC media box


You should be able to use this with only the DVI connection as just a large monitor. You can use a DVI to HDMI adapter as I do believe the display is HDCP compliant. Many AV receivers will upscale to the necessary 1920x1080p resolution that the display needs.

Display powers of with power up of AVC


This is the problem with my LC-37HV4U. I plug in the AVC and the tv/monitor and I get both red power lights (not blinking) but no green lights, sound, or picture. I mean the tv screen stays black! It seems like their is no communication between the AVC and the monitor. I thought at least the screen would light up when the power light came on and being it has it's own power source. This tv is driving me nuts!! Can anyone please help?? Thank you.
