Question about Akai PDP4290 42 in. EDTV-Ready Plasma Television

1 Answer

AKAI PDP4273M1 - Unit powers up then shuts down.

The unit powers up, large AKAI in white letters with blue background appears for 1 to 2 seconds, then AV in left corner of screen lights up,
and no video appears in right corner, unit powers down. A few seconds later same sequence takes place until you unplug the tv.
Discovered that if I hold down the sequence button or the menu button the unit will stay on and continue to display AV no signal. If while holding down those buttons I hook a video input up the tv plays however the audio is low.

I just repaired one for the same trouble. The input to the main processor from the standy switch had shorted to groung. This was probably caused by static inserted when pushing the power button. The processor is not a replaceable part. The part number for the main board is E3761-058010-2. It costs between $140 and $150. I found it on-line at Shopjimmy.com.
Good Luck!

Unplug the power then hold the power button down and plug the unit in again to reset it. If not this is probably a component fault.

Lock message


Hi!
My DMR-ES10 appears since last month, the same message, and lets myself crazy!


Today, after a desperate try, pressing the buttons, I found the solution:

Simple press the POWER BUTTON and STOP BUTTON of the unit for a few seconds...

VOILá: The UNLOCK message appears in the display and the unit return to operate without the lock message !!!

For Lock again, press the same buttons at same way until appears the Lock message in the display.

This is an undocumented command...

I hope to help you!
