Question about Sharp 27C-240 27" TV
Sorry about the subject line containing a model but I couldn't find my model in your list. The problem is that when you turn on the Television the power light goes green for about 2 seconds then turns red and does nothing at all. Just so you know we lost the remote for this some time ago.
The fact that the TV attempts to power by the green light accordingly, and then goes red, indicates that the x-ray protection circuit is shutting it down to prevent any further or more severe damage. You likely have a problem in the B+ (high voltage) line.. Could be anywhere along across one of several circuits but I'd first suspect the HOT (horizontal output transistor), HV regulator and then maybe vertical. There are several tests that need to be preformed and with the right equipment takes about an howr to complete. This is not something you can do yourself - I would assume you don't have the DMM, ESR and 20mHz scope for starters. But a good reputable shop can have this one back on it's feet in an hour and I would guess for under a hundred dollars... If you're not sure where to find a good reputable shop I would suggest going to NESDA's site and researching from there... http://www.nesda.com/locator/state_search.php Good Luck Bill
