Question about Akai PDP4294 42 in. EDTV-Ready Plasma Television

1 Answer

Shaky/Unstable Picture I have an Akai PDP4298ED1 that is 3 1/2 yrs old. This afternoon when I turned on the TV, the picture was shaky. I turned off the cable box and the DVD and checked the TV only...still shaky. Now we've been messing with it for about 30 minutes, and the picture has slowly stablized. Any ideas?

This is power supply issue, one or more of your filter capacitors either bursted and/Or over heats (this is why it becomes better when system cools down after turning it off for 1/2 hour..You have two choices.1. buy a replacement power supply may set you back a couple hundred dollars but it will be plug and play. 2nd you can replace these filter capacitors make sure the can handle 105 deg celsius not the 85 deg. celsius, if you know how to trace the bad ones and desolder and solder new ones on the power supply board, or hire a techinician to replace them for you. Good Luck...

Picture won't come in clear until TV "warms up" for 15 minutes or more


Change the capacitors first per the instructions in the link below. Symptoms could be anything from high-pitched hum to no picture at all. On these defective models, I would start at the caps and work back. It won't hurt to replace them anyway.
