Question about Sharp LC-26D6U 26 in. LCD Television

1 Answer

Sharp Aquos LCD only shows analog

My Sharp LC 26DU had the sound problem I've seen posted here; it was repaired at an authorized shop (was told it was related to the insulation around the audio chip). When we hooked it back up to cable at home, it comes on saying 'analog', and we haven't been able to figure out how to make it change to digital. The original remote had died and we are using a universal that won't show the start up screen menus. Any ideas?

You will prob. have to order a new original remote.  It has the options on it to change from analog to digital.  I don't believe there are any options in the menu or buttons on the tv that switch between the two.

I need some information on buying a ac adapter or power cord for the Sharp Aquos Model LC-22SV2U.


Cord: http://www.newremotecontrol.com/catalog/dyn_accy_data.php?catnum=QACCD3097CEPA
Adapter: http://www.newremotecontrol.com/catalog/dyn_accy_data.php?catnum=UADP-0243CEPZ
On the adapter: I've seen them a LOT less expensive just recently. Google it and choose "shopping" to narrow results. There won't be many, but I think you'll find one at better price in just a few minutes. Try ebay as well; that's where I found repair parts for the same model. Good luck!

The only vendor for this would be sharp or a authorized parts dealer. The cost of these LCD panels usually makes the repair senseless. You may get a cost estimate from sharp at 1800-besharp.

Sharp lc-26d40u No picture


I have a Sharp Aquos LC-40E77UN with the same issue, and have tracked down a single burned capacitor at C7816 on the power supply board, and am looking for info on the capacitor in order to replace it. (Power supply: RDENCA354WJQZ / Delta DPS 208BPA). - Any help with a schematic would be appreciated!)
Since you say the picture went out, it is possible that you might have the same problem, Bad/failed/leaking capacitors are, unfortunately, quite common in electronics. There are volumes of info available on the subject.
Replacement power boards can also be purchased. One for my TV runs about $60 to $120 depending on used or new. Since I was able to see a good picture on mine for a few seconds, despite the burnt out capacitor, I'm opting to try and find/replace the cap myself (using the proper safety procedures), or at worst, have a repair done to the power supply.
Backlights should typically last around 60,000 hours.

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
