Television TV was working fine and switched off as normal. Next day, we switched it on from the TV (not the remote)and although it sounded like it was switching on, no picture appeared and the On/Off indicator light flashed alternately red then green. This is still happening 24 hours later. TV is a Toshiba 29A3TA . Cheers for your help. ps Sound can be played via surround system

Is the video plugged in? It may have fallen out - this is if you are using RCA style jacks - one for video, and two for sound

LCD's use a colorful crystal see through display which only visible when light is shining through it. if you have sound and no picture it's always a faulty PSU. Very easy to change out actually.

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.

the most commun problem with this tvs are the main signal board and the T-con boar , this two board control the tv video

Clicking sound is power relay engaging. If all systems are not functioning properly, unit will shut down to prevent further damage and/or fire hazard

Try pressing the favorite button on the remote. "Favorite off" should display and the remote should work.

Sounds to me like a problem in the tv, not the remote. A short maybe, or a bad connection somewhere.

I would try it on another tv. although as far as the cable goes, on the inside sound and video runs on different sets of wires, so it really could be either. Just need to test it on another tv.
