Papa jim-akai PDP4225 42 in plasma slow on worm up

Try the power button on the tv. Your remote may have dead batteries. If no luck still, it sounds like your power supply unit has gone south. Check for warranty before attempting to repair.

Good luck...

1) Is the TV plugged directly into an outlet or is it plugged into another device, such as a cable box or audio receiver? If it is, try plugging directly into a wall outlet. Sometimes, devices like cable boxes don't provide enough current to power on more powerful newer TVs (like Plasma, LCD, etc) .

2) Check the manual to see if the flashing LED is a code for something you need to troubleshoot. The number and color of flashes may correspond to a problem that may or may not be easily fixed.

Hope that helps. Let me know how you make out.

i believe that this set is built with fans to cool down the inside, check if the fans are running slow, because that could be your problem since you get both sound and picture. i think  that's what it is.

Replace ysus board!!
Check all supply rails before replacing,

It related with Power Board(50%) or Y-Main(50%).
But, if you use the power bar with surge protacton, need to check
the power bar's lamp when the TV is turning on & off.

i wouldn't be worry if:
If the tv just does this phenomena for some seconds specially when there is a change from video analog to digital.
if the tv does the issue only for some seconds and then gets back to normal and stays there for the rest of the day.

That's not an easy question, it seems to me that the supply to the screen is faulty, if the pic gets smaller or larger when it blinks then it maybe the main power supply.....Phil

I had the same problem and solved it with a factory reset. hold menu button dowm for 10 seconds and it will alow you to reset all the colors.

Add av input or change input settings
