Question about Flat Panel Televisions
There is no lumination on the screen although channels change and sound is o.k. Have tried to obtain a service manual without success
Check to see, what format the television set that widescreen etc. this may be all that's wrong with your set. If the problem persists the vertical height needs to be adjusted. Most likely through the service menu, if units under warranty you can call Akai. For further structures.

My 32D40U would turn on for 5-10 seconds (Please Wait would appear) and the screen would go black. Sound Normal. It would also sometimes do this after running 5-10 minutes. I read somewhere that the inverter board would come loose and lose proper ground. I took the set apart, removed the board, and cleaned up the grounding points. I reassembled using some copper paste on the ground points and LockTite on the screws. I used some contact cleaner on all the connectors going to the board. I noticed two cables that are covered with copper shield tape where too tight at their connectors and repositioned the tape to give them some slack. The problem hasn't occurred since the fix.

I also have the akai PDP4273M1 tv with power and no picture and I looked at the power supply board inside and found 1 of the FMG26S chips blown and I am looking into replacing this to see if that does it and if not do a search for SANKEN PSC10165B M and for approx 170.00 you can get a whole new power supply for it and its easy to put in..

I had this same issue, and solved it by putting the TV in "Theater Mode', which can be acheived by hitting the "Theater" button on the remote.

White screen may be caused by failed T-CON board or it is not getting the 12vdc or signals from the main board. Check the fuse on the T-CON board first, T-CON board is mounted under the metal shield.
