I have a PDP4225M 42 in. Plasma Television that will make a loud pop when turned on. A few months later there were horizontal lines that took a couple minutes to clear, next the lines were so bad the TV would shut down and the only way to get it on was to power off then on. Now there is a loud buzzing noise coming from the back of the TV also.

Yeah. I had the same problem. About 1 month ago my AKAI PDP4273M1 TV began turning off...then on. I happened to stumble on a temporary solution. I held one of the buttons down on the t.v. without letting go...and what do you know....the tv stayed on. So I rigged it to where the button (the "source" button) stayed in and I stuck a small object into the hole next to it (a small nail in my case). The catch is you have to use the remote becase none of the buttons on the tv work. Wonderful...so...I got that fixed and then today my picture gave out about 75 percent. What a Piece of S%#* TV. That is all I can say. My 2 1/2 year old TV is a POS and is going into the dump. Can you say hello to a new VIZIO. Hope that helps. Remember. NEVER BUY AKAI TV PRODUCTS AGAIN!!!!!
