Need help! Plasma won't stay on! (update 10/3)

Can't Post

Owner of a 3 year old 50" Vizio Plasma (p50hdtv10a) that may be on its way out to pasture... so I decided to register to hopefully get some positive feedback here. <br> <br>The problem I have is that after powering on, the tv will randomly "click/pop" and turn off. The yellow indicator light flashes and the tv must be unplugged then re-plugged for it to start up again. WHen I first re-insert the cord an initial "click" is heard (same sound as when turning tv on) then USUALLY a second "click" (not as loud) is heard. I have noticed if the second click doesn't occur, the tv WILL NOT turn on at all. The yellow/ green light will flash a few seconds, and then stay lit..... and I can turn the tv on from there. <br> <br>At first this was a one time per day occurence ... Now it happens a lot more frequently and I fear the end may be near. The back of the tv is free of obstruction, no dust or anything. I have read this may be a power board issue? <br> <br>I am actually surprised the tv has lasted this long... but now that its not working I am hoping to keep it without breaking the bank. <br> <br>I am fairly tech savvy, but most of my knowledge is in the car audio arena. I'm willing to give a DIY project a shot here if I can... <br>Any and all help is welcome. Thanks! <br>

Most likely it is in your power supply board. Check for swollen capacitors and replace them if needed.
