Question about Protron PLTV-4250 42 in. LCD Television
I have had this set about a year and when I turn it on the power light comes on (green), then turns orange then back to red as the power cuts back off. I read on another post where you can take the back off the tv. Is there a part I need to replace and where do you suggest to find. Any help would be greatly appreciated. I dont want to throw it out.
I've taken the TV off the wall, removed the cover, cleaned the entire power supply and cleaned all the contacts on all the connectors. I then noticed while reassembling the TV that the metal chassis with all the connections on it did not fit well nor make a strong connection to its data plug.
I then pulled the cover off this chassis and carefully made sure the connector installed snugly, then I tightened the chassis in place. I then reinstalled the chassis cover.
Now the TV seems to be working without issues. It's been two weeks now and all seems well.
As I understand it, when you hit the power button the TV performs a basic diagnostic and in the event an issue is detected the TV powers off, e.g. the red/green/red LED scenario. I believe my problem was a weak connection to the interface chassis, as my TV failed intermittently for a week or so before it completely failed, prompting my above actions.

I have had the same problem off and on since I purchased my protron 42" lcd. I have found that if I hold the power button to the tv a little longer, I rarely have the problem. Hope this helps.
