Model 55p8288 46" big screen Magnovox. On / Off buttom blinks but doesn't turn on. My 11 year old played with it over and over by pushing the Source Select button after I had given up. The TV turned on and was working for months until I pushed the Source Select button again to try to get a DVD player to work.I think that button may be defective. Am I on the right track?

I have tried soldering it but I need to know if I am soldering at the right point.If I push the Source select button or the channel button the blinking light on the on/off switch will stop for a couple of seconds and then resume blinking.I wrote down the P{hillips part number which is 313501707611, do you know where I can get this part?

    however, the blinking of the power indicator, is reflecting a fault in the set. Try powering it down for 30 mins by unplugging at the wall to do a reset, then power up again and see if the fault continues.
    If you have no luck, I suggest a repair man is in order. repairs can get complicated to TV, and it is always cheaper to professional fix the original fault, not try to work out what has happened from other attempts at repair.
    I am more than happy to answer any other questions you may have about
    it, please get back to me here, or use the ASK function to go straight
    to me :) If you are still unsure, have problems, or we need to look at

I have a old 52 inch sony tv turns on but picture blinks off and on whats wrong


A lot of their older sets (both regular TV sets and big rear projection set had this issue).

In either case it may mean with age the MASTER SCREEN control/s need to be adjusted slightly up---if too dim a picture it will blink.

A model number would tell me what to try.

Models beginning with KP are large projection and ones with KV are regular sets.

We have a Mitsubishi Big screen projection tv model no. VS-50705. when the on button is pushed it clicks like it wants to turn on but then doesnt. When I unplug and plug back in the green light flashes...


This could be a trouble code for your model television. Try counting the blinks and note any pauses in blinking. It could be a one or two digit trouble code. Then once you have that number, type in your tv model along with the words "trouble codes" or "diagnostics codes" or "green light blinking" and see what you get. Hope this helps...

3 blinks means the convergence circuits are shutting the set down. Usually the convergence ICs will take care of the problem, but I would recommend getting the service manual from the following link, as they will provide you free support to help you diagnose why it wont start as usually the convergence ICs wont prevent a set from powering up, unless another component in the convergence circuit has failed.
