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

Hello! I have a Sharp Liquid Crystal TV (37" display) and my menu options, specially the picture menu, is fixed. can you help me "unlock" it? Model # LC-37G4U


If the AVC System is switched on but it does not appear to be operating correctly, it may need resetting. In this case, press RESET, shown in the diagram, lightly with the end of a ballpoint pen or other pointed object. This will reset the System as shown below. • AV MODE resets to STANDARD • TV channel returns to initial channel setting (Air:2ch, Cable:1 or 2ch) • Twin picture resets to normal • Audio setting initializes • Dolby virtual resets to Off • Image position initializes

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...

AVC BOX PROBLEM


I have had very few problems with the AVC boxes with this model and find most times the shut down is due to a failed power supply mod. in the tv.

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.
