All for the inputs on the back and front work for a short while then the screen goes blank but audio still works. The only input that works all the time is the HDtv coax input.
What part do i need to replace? Were do i get it?
Re: Mitsubishi WS-65909 Video Inputs Stopped Working
Finally got a tech to come out to the house ($99 to diagnose). He determined it was the Doubler Board. Got a quote from this company to repair it for around $800. I was able to watch over his shoulder. The board is really simple to replace. I just need to find it.

It sounds like this TV is being used only for the PS3. We'll need to troubleshoot this through a process of elimination.
If you're using Component Input 1 and audio, try using Component Input 2 and audio instead. If this set of inputs provides working audio and video - you can stop. Or, try going back to Input 1 once more. If Input 1 now works - you may have simply made a better connection. If it doesn't - then there's probably an issue with input 1 on the TV.
If moving to Input 2 above still didn't solve the problem, you should try using a different set of audio cables between the HDFury and the TV. If it now works, the original audio cables are faulty.
You can check the HDfury setup on another HDTV with component inputs with it connected to an HDMI cable. if the HDFury wors, you know the device and all the cables work. If you do this test and it works with your PS3, then you know that the PS3 is providing good video and audio signals via HDMI. If the problem follows the PS3 - then it's the PS3 at fault. If everything works perfectly on the second TV, then there is some issue with the audio amplifier / inputs / speakers of the Mitsu TV. You could get a cheapo stereo amp and speakers - or a set of computer speakers for audio - it all depends on how much you want to spend for sound.
