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!

I found one of these at the dump with the same issue. Bought a Z sustain board for $75 , replaced it and it works great. I plan on installing some PC style cooling fans in the cabinet as heat is what destroys these sets

Picture on Akai PDP4273M1 suddenly degraded drastically - no whites, very low contrast. Turned it off for 10 minutes then back on, instead of bright blue I get most black splotches with some blue. Any...


You could smash the TV and find that it will work better or call a local repairman. I know the exact problem with this TV, but only a technician should even open a TV. The guy I got the TV from totally butchered the inside of his Akai in a failed attempt to fix his TV himself. Instead, he created a fire hazard and is lucky he did not burn his house down.

Akai TV repeatedly turns off and on


Yeah. I had the same problem. About 1 month ago my AKAI PDP4273M1 TV began turning off...then on. I happened to stumble on a temporary solution. I held one of the buttons down on the t.v. without letting go...and what do you know....the tv stayed on. So I rigged it to where the button (the "source" button) stayed in and I stuck a small object into the hole next to it (a small nail in my case). The catch is you have to use the remote becase none of the buttons on the tv work. Wonderful...so...I got that fixed and then today my picture gave out about 75 percent. What a Piece of S%#* TV. That is all I can say. My 2 1/2 year old TV is a POS and is going into the dump. Can you say hello to a new VIZIO. Hope that helps. Remember. NEVER BUY AKAI TV PRODUCTS AGAIN!!!!!

GOOD DAY ND GOOD LUCK;

TRY THIS, IT WILL CORRECT CONCERN:

50V500 ONLY
GHOST: May be described as "Out of Convergence" but ghost is still attached to main image.
CONDITION:
A "ghost image" appearing to the left or right of images in the picture. Can be varying shades of a primary color (red, green, or blue) as well as gray. Can easily be seen in the 4 x 3 mode, at the edges of the picture.
CORRECTION:

To correct the problem, please do as follows:
  1. Access I2C Menu. (See page 57 of the Service Manual).
  1. To enter the I2C Service Menu, with power off, (on the front control panel) press and hold the INPUT button. Then press the POWER button for two seconds. The following Service Menu will appear.
03b_ghost_image01.gif Figure 1
  1. BEFORE CONTINUING: CONFIRM THAT THE R, G and B DRIVE ARE SET AT 40.
  • Be sure to press SELECT after each change to SAVE the new Data.


  1. Using the Remote Control joy stick, scroll down to next page (see Figure 2) until LCD ADJUST is highlighted.
03b_ghost_image02.gif Figure 2
  1. Move the joy stick to the right to cursor right once. The next page will appear with the word GHOST highlighted.
  2. Cursor right again, and a white screen will appear with a BLACK SQUARE in the center, as in Figure 3. You will see LCD ADJUST, followed by “SHP” and a number (value).
03b_ghost_image03.gif
Figure 3

  1. If the unit is out of adjustment, you will see a gray ghost on either side of the black square. Move the joystick to the right or to the left until the ghost disappears. The number values will change up or down.
    • If the ghost adjustment is off with a lower value, there will be a ghost to the left of the square.
    • If the ghost adjustment is off with a higher value, there will be a ghost to the right of the square.
  2. Once you get the square to look good without ghosts, press "SELECT" to save any data values that have been changed.
  3. Press the "EXIT" button three times to return to normal picture.
  4. Adjustment is completed
  5. I HOPE THIS WAS HELPFUL, big IRISH.

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..

OFF AFTER 10-15 MINUTES


This is usually caused by damaged capacitors (Akai uses very cheap components) on the power supply board. There are nine large electrolytic caps that have to be replaced. Hope this helps you out.

Screen powers up then goes blank after 2 seconds


Hi, was there a resolution to this? I am experiencing the same problem with LCT3285TA purchased at Radio Shack in Media, PA. Radio Shack has refused to service the unit and has put me over to Akai for the manufacturer's warranty. I'd like to know what to expect and if this problem with the Logo coming up and the unit shutting off/restarting can be easily fixed, thanks.

Westinghouse 32in HDTV-Ready


I called westinghouse with a similar problem(my picture shows up but all the white turns blue or somtimes pink).
they say the problem is similar to that of the xbox 360's red ring of death problem. Now what needs to be done is the unit needs to be unplugged completely for about 30 minutes. this allows the unit to completely cool down. and when the unit restarts and heats up the troubled connections will reflow and all will be fixed.
I tried this and it worked well for my TV. but it is only a temp fix and will need to be done again if the problem occurs.
