Sharp lcd screens are very easly damaged especially the larger screens,this could be at fault even though it looks ok,try shinning a light on the screen and checking every inch,could be the internal screen that has damage hence why not powering up.
Failing that it sounds like an internal short.

I had this same problem with my 23" cello TV. It was a problem with the internal power supply - specifically the 12V output. It had fallen to 5V. I noticed that the three electrolytic capacitors (EC7 EC8 & EC9) had bulging tops as though they had been damaged. I replaced these and my TV is now working again although I don't know how long it will last. The three capacitors were 1000uf 16V types. I replaced them with 35V versions (which are physically bigger and a tight squeeze). Your TV repair shop should be able to replace these faulty components in under an hour.

when you turn it off your light blinks because your internal fans are still spinning allowing the inside of the chassis to cool off, hence the reason you dont watch a DLP TV and then unplug it. DLP's are JUNK

I had the same problem. all the service reset would only make the display come on for a few second with no "k" on the screen - only the channel would show up. I purchased a complete set of board for the lcd on ebay, and started swapping them one by one. The inverter boards were the culpret. Tele working 100% since that board swap.
