My pioneer 5020FD Kuro tv. when I plug power to the unit, a blue light blinks 8 times pause 2 sec. and blink 8 times repeating this and if i press power button it clicks red light and makes a clicking sound and goes back to the blue light blinking again, it did this once before and the picture came on fine until i turned it off and now it just blink the blue code.
Sounds like there's a short in the power somewhere. I'd start with unplugging it then checking to make sure all cables and/or cords are properly connected (i.e. make sure there are no loose cords anywhere)
check the capacitors and replace the power components check mother board also .. not handy with electronics and soldering call tv repairman 75-150 dollars Fix ?????
The power supply board have problems,it not giving the tv the right votage anymore.That why it shutting down,not sustancening power to the tv anymore.That the board,where the power a/c cord plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish power board for the replacement.
We have a 50 inch magnavox plasma screen. We found and used a fix from fixya! It only costs us $34.00 campared to the $300.00+
anyone wanted to look at it. The problem was on the powerboard but was two little capacitators with the model #3300 10v. We carefully took the back off the tv and removed the power board, went to a local electric supply store and bought the 2 parts for $2 each, we then found someone (tv repair shop!) to sauter the new ones on! Got it home put it back together and it stayed on, no depressing shutdown after a few seconds! you can find a picture of a fried capacitator on yahoo images, they are supposed to be flat but if defective will be bubbled at the top or even split! I am calling Magnavox today to complain that they are not recalling this part that should have been a better quality capacitator! Hope this helps some people!!
The above fix, listed by Tom saved us!! We did as instructed and took off the back of our 50 inch Magnavox plasma tv. We were not sure what we were looking for so we googled capacitator (image) & there was a photo of a fried capacitator! Sure enough we noticed ours were "fried", we took out the board and went to an electronic supply store, bought the 2 capacitators ($2.00 each!!) and then found someone who did tv repair to sauter the new capacitators onto the board. (It is important someone who know how to sauter and recognizes polarity do do this for you) All in all we fixed this following the above instructions for $34.00 and our time. For a month we were told to spend hundreds getting a new power board!
Kudos to you Tom & thanks so much!!
Un plug the power to the Plasma Screen and also to the Media Receiver for ten minutes. Disconnect the off the air antennas both A and B. After ten minutes plug in the plasma screen then the media receiver and turn on wi the remote control. You should now be back in operation. I was.
Also It may not be a bad digital tuner. The TV Guide feature is active even when the zip code is set to all 0s so if you have an over the air antenna attached the TV will look for the TV Guide info and if it can not find it because of a weak signal or the chanel it is tuned to does not carry that information the TV thinks that tuner does not work which triggers the 12 flashes. Also on power up the gray box with the waring message "Plasma Display Starting Up, Please Wait" appears and the screen is blank.
