Personally I would suspect the high voltage block for this set is bad.

This is an indication of protection error and might require attention of a qualified service technician.

Buy a remote control that have setup codes For Technica TV.

My TV surname off after 5-15 minutes of use. The red light in the front blinks once every 3 seconds continuously. If I hold the power button down on the tv, it will turn on and do the same thing.

this is from your producer: Product Description ? BASIC OPERATION OK ? everyone knows what a handheld remote control unit does for your home electronics. You can control your basic four (4) components: TV, DVD player, VHS player, Cable or Satellite tuner. Setup is simple for these basic 4? put in the batteries, look up the manufacturer of your component (Mitsubishi TV) and note the possible 3-digit ?program codes?? turn on the component, press the remote control?s PROGRAM button until the light stays red, press the component button (i.e., TV), enter in the ?program code?, and press the ?power off button? ? if the component (i.e., TV) turns off: you are programmed! If the component (i.e., TV) doesn?t turn off, then repeat the sequence using another of the manufacturer?s program codes until it does. Easy ? took me about 3 minutes to program my old Zenith TV (in the bedroom), my SONY DVD player, and my Mitsubishi S-VHS player. No problems at all. HOWEVER, in case you do run into a component for which the ?program codes? don?t work? you can go through a sequence to self-identify the coding. While I won?t go into it here, it is only slightly more time consuming than the other method. As my codes worked fine, I can not address this aspect, so I won?t make a claim we didn?t test.
