There is a diode located on the power supply of this set that has been a common problem. The location number of the diode is d558. If it is shorted then it will need to be replaced. There could also be other possibilities but this the most common problem that I have found in my notes. If this is the problem, a repair shop may get any where from $50-$150 to fix it. If you did it yourself, the diode would only cost a couple of dollars.

I have sourced out all fuses and bulbs, yet continue to have a rapid right turn signal. I don't know where else to look. help?

replace the right rear bulb. the quick flashing indicates a bad bulb. it could be a wiring problem to the rear for the signal light that you will have to check out starting at the socket and working forward.

No picture, green flashing power light. How bad is this?

The flashing indicates something is wrong (missing or bad) the fact you get the display means panel (main screen unit) is good.

This suggests to be (instinct) the main board that processes all signal from all inputs is bad; it could be a missing voltage in the power supply but a check with a voltmeter would answer that.

The problem here is you can check a few things and then you are in a position where you have to gamble and buy and try a board.

It can get expensive to fix it this way---gone are the days of looking for one bad part (they only sell boards) and with that the lifespan of these (all brands Plasma and LCD etc) are 3 to 5 years.

Sylvania LC260SS8 -No power, will not turn on

The most likely your right, the TV has a power supply related problem.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.

TV is not coming on red light flashes in front

Ok, this rapid blink is caused by a power board failure. The literature states that one or both of the on board capacitors have been disabled because of an abnormal current flow through the circuit components. are you familiar with a multimeter?

--If the Power light is flashing red thanits definately problem with the Actiontec Router --As you have checked with different power source, the possibility of bad power source is no more --May be due to some voltage fluctuation the modem is gone bad.
