It sounds like the gas in your screen has exhausted it's life. From the information I have gotten from different manufacturers, there is about a 5 yr life expectancy on the screens of most plasma sets.
My guess from the symptom you describe is that you will need to replace the screen.

I am fixing a gtw -p46m103 tv when I plug it out then plug back in it work for a while then all function stop work

You're going to need to open up the tv and do some resoldering of some components. If you don't want to do the soldering find someone who can. Or if all else fails I'll take it off your hands just let me know.

I have a gateway model gtw-p42m102 and there is no picture or sound. ther is a green light in the back that blinks 8 times and starts a 8 count again.


Gateways are an absolute nightmare to work on. Basically, there are no parts available for them, except from Gateway, who used new sets parted out, and they charged incredible amounts for service calls (if you were lucky enough to live in a metro area with a gateway store nearby).

Most shops will turn the away. The Y-sus and X-sus boards are very prone to problems, and unfortunately, are not available for replacement.

I'm sorry to be the bearer of bad news. Especially considering how much you probably paid for this TV. I have a Gateway, but only because it was free, and I have to repair it every 6 months.

Gateway P46M103

Everyone says that it is a problem with the y-sustain board. and while that may be true in the end the cause of the faulty y-sustain board is cracked or missing solder on the power board lead connection to y-sustain.
