Joechillin, how much TV repair experience do you have and do you own a mutimeter as well as an osilliscope? Ok first thing your going to need to do is to get a schemtic diagram. Find out with the scope, if the horizontal drive pulse is there when you turn on the set. If it is not then go back to the SMPS and check that. If it is, check the drive all the way up to the horizontal output transistor. If it is good up to there, and still no sweep power supply? Your going to most likly need to replace the flyback transformer and the horizontal output transistor and go from there. If you are there with this, great. But really man if you have no TV repair experience, we cannot teach you how to, as there are alot of factors involved. There is also alot of High Voltage inside these sets when the plug is even out of the wall. Also everything inside these sets is mounted or soldered on a printed circuit board. This set is a solid state TV and there are NO user replaceable parts inside. My friend, I would Highly recommend that you call in a trained service person to assist you with this repair. Good Luck

Hello

The light flashing is some sort of an error code, count the number of times it flashes then call the manufacturer's tech support and tell them the standby flashes in increments of 5 or whatever yours is doing to find out what the code possibly means.

No picture, siren type noise as restarting

My Toshiba dlp 62hm116 was used for 3 months then stored for 2 years, I turned it on yesterday and it makes a loud grinding noise which I think is probably from the exhaust fan area and the picture is black except white at both vertical sides. It worked fine the last time I used it 2 years ago. Any ideas?

Watching dvd, great pictue and all of a sudden black out

7 Blinks is the failure of the SC/SU/SD PCB's (1 2 or 3 depending on how lucky/unlucky) you are.

Panasonic have a great warranty usually. Give them a ring, it has failed.

The flashing LED is the fault code.

Flashing red center light

With most flat panel TVs, the TV turn itself OFF when it has a fail electronic part and the red light starts flashing. They call this "Protection Mode". The flashing red light should be a error trouble code.
But, it's weird that everything is working and the red light is flashing. Since you just recently bought the TV, I would get it check out while it's still under warranty. Better safe, than sorry.
