After I turn on the TV, there is sound but there is no picture at all... sometimes the picture comes on after couple seconds later it goes off... also the timer/standby indicator is blinking continuosly... I left turned on for hours but nothing has changed... the tv manifacturer date is 1999 ,

what is the last time you do??

definitely, something wrong with it. TV shouldn't take more then a few seconds to start, I suggest, while it still under warranty, give Sharp a call to get it fixed.

Bad caps in the power supply must be replaced .

Sounds like the digital board needs replaced.

IT SOUNDS LIKE DRY JOINTS ON FRAME CHIP

turn tv on picture comes up 2to3 seconds later tv blacks out then stand by red light flashes 4 times in a row repeatedly..can not turn on or off when stand by light starts flashing but before tv blacks out you can turn tv on and off repeatedly and picture and sound work.You have to unplug power cord for 30 seconds after stand by light comes on to get tv to turn on.

I have the same issue with mine and have a solution that sometimes works. I had a repair guy come to check it out and he powered off the TV so that the red light was no longer blinking, then he unplugged the TV for about 30 seconds or so and then plugged it back in. He then turned on the TV and it worked. He said it would cost about $400 to fix the issue (some circuit or something). I have since expeerienced the on/off problem (due to power outage) and now I cannot get the TV to work. But at least give this solution a try and please post to let me know if it worked or not. Good luck!

Your two options are to take it to a service shop, or the more likely and probably more cost effective option is to purchase a new Television. The newer model will have a far superior picture quality, cost less per inch of viewable area, and likely have more features than your prior T.V. as well.

good luck
