Most likely you are on the wrong source chanell. look for an AV/TV button. keep changing that untill you get to the TV stations. If you have a set top box make sure it is turned on. Also the appropriate AV channel will be the one that the set top box is plugged into.
The tv has a high voltage problem, sets that last ten years or more have come to the point where a new tv should be considered, because even if you fix it there is good chance something else will go wrong, remember the parts are twelve years old.
I replaced 3 capacitors and fixed this problem. They were 1-10v 1000uF and 2- 10v 3300uF electrolitic board mount capacitors. Easy to spot on the power board, the tops were bulged up. $5.54 later it works perfectly now.
I have a solution for The United States of America! "If We Don't Make It, We Don't Need It".
Personally, I believe if we went back to actually manufacturing things in this country and stopped importing everything, a lot of these problems would STOP!
According to Sharp it is a software problem. Engineer came, installed software update ,10 minute job.....TV worked fine for 1/2 day unfortunately: Then images turned black and white in all channels TV turned itself off, and stanby and OPC buttons started flashing. When TV came back on its own 10 mins later , screen had 2 large square staines superimposed in image (as if it was a burnt screen)...Engineer will be back next week...all quite sad really for a new TV.....will keep u posted
The problem is in the standby power section. Check the fuse, R607, or burnt IC601, fuse R612 and VD relay 601 should show open. Its possible it could be the high voltage area of the power supply.
You can try unplugging the set and cable and let it sit 4 to 6 hours. This is a hard reset.
If it still doesn't turn on after the hard reset and the fuses and relays are fine, and you don't smell anything or see anything burnt. Then you'll need to call a TV repair man. They normal start around $150-$200 to fix the set.
I hope this helps.
