    which control moduel because i think i have the same issue and i been trying to figure it out for a week now. i swapped out the main power board with a known good one and still same issue and it has a sub power board i thought that might be it i pulled all the capacitors off and tested them all but the capacitors seemed to be fine to me. im kind of stuck now.

    The control module is usually part of the power board as a whole. So replacing the power board will fix the problem.

    A capacitor will test good 99 percent of the time, but will not hold a charge under normal operating conditions.

Tv powers up but goes directly into stand by mode


An Electronic component has failed. Unless you can repair circuits, take it to a shop or friend who can. Consider cost of replacement. A few hundred will fix an old tv, a couple more and you have a whole new unit.

I currently have my 55HDX62 Hitachi Plasma wall mounted. I am moving the unit to another location and wish to place it on top of a TV Stand. I do not currently have the table stand which came with the unit...


Even you find it the shipping won't be cheap. They do make universal stands for LCD/PLASMA TVs. You may want to see at Walmart or a similar store if they carry the universal stand.
About a year ago a customer brought a 55" Panasonic plasma TV to our shop, and we asked him to bring the TV with the stand he found out his wife, trashed it and he made a nice stand out of pieces of wood. If you keep looking on ebay you may be able to it.

Best of luck

PIONEER PDP-424MV Plasma TV


Hello,

I have the same TV, well, nearly, PDP434.

The only part I ever sell for these is the main PSU (power supply).

The TV "checks" it self using a self diagnostic system. As soon as it discovers a problem, it shuts down and blinks an error code on the front LED.

It always seems to be the PSU.

I hope this helps at least a bit.
