Question about Sony PFM-42B1 42 in. HD-Ready Plasma Television

Same old PFM-42B1 problem - is it worth the $ to fix?

I have a Sony PFM-42B1 monitor that someone recently gave me with the dreaded "6 flash" problem. If I turn it on, the monitor springs to life with a "staticky" screen(no video in connected to it yet, I'm missing a cable), much like any TV without a signal. Then, about 1/2 to 1 sec. later the fans turn off and it shuts down. It restarts again(it does this 4 times) with the same results, and the status light flashes numerous times(I counted roughly 6 between 2 quick double flashes). Now, can this be fixed, or any component replaced? I popped the back off on the hope I'd see some IC burned up, which I might be able to replace, but everything looks fine. It's amost as if the circuitry is getting a false "shutdown" signal after it boots up.

I've seen a bunch of "quasi" explanations for this but nothing definitive. Can anyone help?

If you call sony technical support they will send you a shipping box to ship the unit to them they will then repair it and ship it back to you. I've had mine back for a year and it works great!

By the way this was done at no cost to me. Manufacturing issue.

Ok to clear everyones issue on the 6 Flash fault.
If the tv powers up with a flicker of the screen and repeats this 3 times then shuts down the Plasma Panel (PDP) has died and only a replacement panel will cure this problem. This is getting a common fault now due to the age of these sets although they do still give good results. One more thing if you decide to be brave and buy a 2nd hand panel dont repeat DONT just think you can unplug it and plug the other panel in as you can't due to voltages from the power supply to the screen are set preset to the panel - You must set the voltages on the power supply to match the panel ( usually on a sticker on the PDP panel). I hope this clears lots of 6 Flash issues up.
