Try the 'bad' sky box on the good TV.
Swap the cable from the good LNB socket to the 'bad' one. If the good side stays good, the 'bad' cable or connector or lead or sky box is at fault.

HOW TO RESET YOUR TV REMOTE CONTROL - TV REMOTE CONTROLS AMAZING SECRET

Hello,

The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.

The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board. You might be lucky it's just a blow fuse. Also a defective transformer can cause your TV not to power on.

All these can be checked on the power supply board.

But more often bad capacitors causes problem on the power supply board. I do not think the power board needs replacement, rather those defective capacitors is causing this issue. Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.

The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)

You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.

What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).

You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors). After replacing these capacitor(capacitors) most likely the normal operation will be restored. Or you can by a refurbished complete power board to save you some stress.

Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.

If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.

I hope this helps.

Regards.

These type of failures is normally due to a defective power supply.
The power supply is not supplying enough power to the main board due to defective capacitors.
I would suggest to open the back cover of your LCD and visually inspect the capacitors for bulging or swelling on the top.
Be very careful when handling the power supply, as some capacitors in the primary rectification side would hold a charge and could cause injury..
Let me know if you required further assistance..

I have had what is fundamentally the same problem. I have a desktop PC that I am plugging in to my Panasonic Viera TX-32LZD80. I am using DVI connection plugged in to HDMI port.

The solution is fairly simple; use the Menu button on the TV remote to get to the Main Menu for the TV and then select Setup which should be the fourth of four options. This will get you to the Setup Menu for the TV for the current channel. Look for the Picture Overscan option, it will very probably be set to On if you have the problem of %5 or so of display being missing on all sides.

Switch Picture Overscan to Off.

This immediately should solve your problem. A note of warning on this is that I suspected this was the problem but when I first looked at the Setup Menu I could not find the Picture Overscan option.

If you are unable to find the Picture Overscan option then trying fiddling with the Aspect settings. You will probably find it set to Auto. Switch it to 16:9 and you should find the Picture Overscan option will be available from the Setup Menu.

Hope it works for you.

It would be best to contact the manufacturer or TV repair facility. This is a car forum and we wouldn't have the right info.

That sounds like a protection against overheating. Remove the case and vacuum any heatsinks or fans you might see. Also make sure it in in a well ventilated spot, with nothing on top of it, or another heat producing appliance under it.
