Sharp CX80H6 Has sound, no picture for TV or AV OSD works

I'm having the same problem with a Pioneer AV Receiver VSX-523. I can't see OSD using the new ACER monitor I just bought. If you have a solution, please let me know. Thanks.

Check whether it is in AV mode. If not, check and replace its tuner.

Chepe_77,

You are absolutely correct. The reason why you cannot change your audio and video settings are due to the fact that you are in "Dynamic Fixed". Which is one of your many av modes. Av modes are different preset color settings and dynamic fixed is the only one that will lock your settings. Best Buy set it that way so that people could not just come by and alter the settings on the unit. AV modes are on all sharp lcd products and even though you have the wrong remote you should have an av mode button on the remote that came with it. Try pressing the av mode button and see what happens. When you press the av mode button, you will see your av modes change at the bottom of the screen. However, the issue still remains that you have the wrong remote. So there is a chance that you may press the av mode button on the remote that you have, but it still will may not work ONLY because you have the wrong remote. If the remote you have does not work, I GUARANTEE that pressing the av mode button on the proper remote will take care of that. If you dont want to purchase the remote from sharp, www.partstore.com is a good place. Good luck to you

For this to work please make sure your TV is tuned to its "AV" input channel. It will not display a picture on any of the normal tunable channels.

Check to make sure it is on either the AV 1 or AV 2 channel

The lamp has to be lit for the OSD to be present. the video processor is likely where the problem lies. I would suggest one of the following circuits SD Ram Circuit, Scaler input and or Capture circuittry and quite possibly the light engine itself all though the light engine would be very last on the list.

That sounds like a European model. Sorry I do not have a clue bout those monsters.Do you have the set in AV mode or antenna mode?

You may have a problem with the video switching IC. Stargazer

The problem you're describing sounds like a tuner problem. BUT you say that you have the same problem with A-V input too. That's weird!!! Possibly the electronic TV-AV switching circuit is messed up and stuck in the TV (tuner) position. If this is the case you DO have a tuner problem and a switching problem too.
