Sharp LC-52SB55U doesn't work with any remote

I bought a Sharp LC-52SB55U from BestBuy a little over 30 days ago and it worked fine up until two days ago. My programmable remote stopped working. I tried the remote that came with it and my comcast remote but that did doesn't work either. The buttons on the side of the TV work but nothing with a remote. I tried the recommended reset of the factory remote which didn't work either. Anyone have any ideas?

Well, there is a way to have the clearest possable picture. Get HD cable TV box that is HDMI compatable and watch only HD channels. Or buy a blu-ray player, hook it up via HDMI and only watch blu-ray disc in 1080p!

Check your owners manual look for the section that tells you how to adjust the televisions features using the on screen menu.You probably Have it set on auto adjust. You must turn this feature off, to use the manual controls. If this does not help go to the Sharp website and search the frequently asked questions and troubleshooting sections. Search for your problem and similar one that may have answers. If all this fails you, call technical service and ask them for help with your problem.Hope this helps you with your problem.

SOURCE: Flickering screen (LC-52SB55u) with HDMI

Do a quick google for this on the AVForums site where you'll find numerous threads covering this problem. First, select the HDMI input before turning on the blu ray player. The handshake over HDMI is the problem. I have the same problem with a Technika blu ray which is fine on my other TVs.
If this doesn't solve it then you ned a firmware update which can be downloaded from Sharp's website and installed using a USB pendrive or by PCMCIA card from Sharp if you have an older model with a rocker on off switch and no USB update port on the back of the TV.

SOURCE: How do I hook the

Your HDTV would have to have internet connectivity, either an RJ-45 ethernet jack on the rear panel or wi-fi capability. Sharp calls it the AQUOS NET feature on the TV and is usually an ethernet port. If your TV does not have this capability, you can use a laptop and hook this up to your HDTV. You still need high-speed internet service and a Netflix account.

Go to turn on tv and all I get is flashing red light and tv won't turn on. Was working the other day.what do I check?Sharp LC-26GA5U


Hi,

Try unplugging the TV from the power point and leave unplugged for 5 min.
Or the batteries in the remote may be flat, try replacing the batteries.
If this doesn't work the TV may have a fault.

I hope this helps

Unplug your TV for 30 seconds then plug it back in , remote should work after that. Press CC button on your remote until you'll see CC OFF.

Television displays in blue , only checked all


For your remote problem, mine has stopped working a couple of times and here is what Sharp had me do: Take the batteries out of the compartment. Next press and hold down the power button on the remote for a count of 30 seconds. Return batteries and the RC should be reset. As for the other problem, I had a similar thing happen tonight, hence I am on this site looking for help. My remote quite working, so I did the above, to no avail. I noticed the channel number box was frozen on the screen. I could not turn the TV off manually and had to unplug from AC. I plugged it back in and got sound but no picture, just that bluish dark screen. TV would not turn off. Then I got nothing, no sound, no pic. I left the TV unplugged for several minutes, 5 or so, plugged it in and it did work and is working now, RC too. You might try unplugging it for an extended time.
