Mitsubishi WS-55311, 4 yrs old, flashing screen on all inputs
Until now this TV was working perfectly. Recently, from any input setting it will suddenly flash a blank screen (all black) in a pulsing manner but in irregular increments in the middle of watching TV, playing XBOX or even with just a blue screen. When this even happens neither the remote nor the TV operating panel function. One time the volume just spiked up to full blast without me touching anything. I checked all connections and they are secure.
Please help. Is this just a simple issue or is my TV possessed??!!!!

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.
Before you replace a board, please double check or use different cables, make sure the cables are in the proper out/inputs, rgb to rgb. Try 'comp' 2. Composite vs component uses two different paths to produce a picture. Also, after taking tv's back off ensure that all boards are seated properly, since this happened after movement. CAUTION: make sure the unit is poweless, unplug tv. Let me know. Good luck....
When your tv shows a blue screen it not getting a signal!! In your mit's you have to go into the customer menu and turn on the input/device. The device control is on the remote, click over to input and activate (enter). Also, look into owners manual, the customer service at mit's will step you through it if you wish. Note: put cables into comp 1 (eg), make sure colored cables are correctly inserted, and audio. (red, blue, green) red/white; audio.
First suggestion is to unplug your unit for 24 hours, if does not correct your concerns, you may have fluid leakage from the tubes onto the pc boards. Make sure you have proper air venting around the tv. If problem persist call factory authorized dealer in your area. good luck
