My monitor fails to start and the power pack shows 12-22 repeatedly

Hi I switch on my monitor it goes to start up for a second or so the fan starts to run, it fails to start, the screen with the power pack repeatedly alternates 12 to 22, sometimes I get a quick flash of 53 it then goes to 99 and stays there. I do not have a manual so can't tell what the numbers mean.I hope you can help. best wishes Tesz

Re: My monitor fails to start and the power pack shows...

Howdy, I guess you're talkin' about a : Sony PFM-500A2W Plasma screen ?? The fault-codes your talkin'about " 12/22 " + continue re-starting " is a common problem with those plasma screens. It gives an " low power " message on the PDP module . We started today a discussion-group at to get a clear picture at the Sony. We allso placed a " fault-code " list , so users can see what those codes are standing for. The main target of the discussion-group is ..... sharing knowlegde and information about the Sony PFM-500A2W. Schematics Problem solving fault finding Where to get any kind of parts. Print layouts etc. etc. The followin' link shows the discussion group. Please give us some time to startup the group. So don't give up any hope ;-) Best regards , EuroNet 2000 The Netherlands

I have a th-42px80u panisonic viera turns on for 30 seconds red light blinks 8 times which board do I replace

Hello Charles May,

Top line...
be safe & always verify your CIRCUIT BOARDS YOURSELF.

Typically flashing means the main board has a level of logic that has been offended by the power board... Sounds like you have some experience inside these sets... Never-the-less: Take pictures before you start (good usable pictures, precisely how things are routed)... always wear protection... static discharge (ESD) can DESTROY the most robust circuit packs.

See wristband below... Then look up Tampatec & watch him prove my point when he smokes some collateral packs... but is big enough to admit it... (good viewing).

As for me... the boards are to cheap to be recommending any HOT work... (dangerous)... and you really have ONLY two major boards to try...!

Power board & Main-board... My vote goes to the Power as the first best candidate. (30 seconds usually means cheesy failed capacitor)..

But that's why they call it an iterative process... Besides you always wanted that spare circuit pack.

Careless is the only guarantee you'll get from me. If you go in carelessly... I guarantee you will FAIL.

Good luck.

Samsung HLP466W goes off after turning it on for about 20 seconds, why does it do that?

The power supply tries to start for about 20 seconds, then fails. It will repeat this routine until eventually it fails competely.

I have and olevia 26 in tv..when i try powering the TV on.. shows blue input screen for a split second and picture goes out to black screen..not sure if still have sound but...i hit power button again blue...

There's a good chance you have failing electrolytic capacitors either in the power section or the inverter section or both.
Any caps in these sections that look bulged at the top, or bulged/leaking at the bottom need to be replaced.
If you repeatedly turn it off and on, eventually it'll probably stay on, but every time you turn it off, the TV will get harder and harder to start up until one day it just won't.
Sometimes you have to do the opposite to start it up and unplug it for some time and then try again.

If you aren't tech savvy, don't worry, read the rest of this solution and watch the videos.

If you are handy with a soldering iron and can identify the power supply and inverter / FM section for the backlights, an inexpensive handful of capacitors will likely fix you right up.
Match the capacitance on the capacitors. Go over voltage if you can, and still have them fit.
IE - it's not a bad idea to replace a 10V cap with a 16V or 25V or even a 50V, but don't replace a 680uF cap with a 500uF or a 1000uF (unless you are positive it's only doing ripple filtering, and even then, you should go OVER, not under the uF rating).

Most of the caps that go are 10V 1000uF or 3300uF.

I found some great videos of the procedure (for many Samsungs with the same issue) on youtube.

As you can see, this issue spans plasma TVs, as well as large and small LCD TVs and monitors.
The parts are cheap, and skill required is minimal.
Cpacitors are less than a buck a piece typically if you order online from a place like plus shipping, and they usually arrive next business day.

Pioneer pdp 502mx goes to standby no picture after power on

Contact Pioneer at 1-800-421-1404 about getting an in-home power supply replacement. This is a known issue with some plasma displays. Some of you would experience a loud pop and then the power supply fails. You get a red light below the ON button, when you press on, the red light will turn green for a second and then back to red. The plasma display will not turn on after the power supply fails. Call Pioneer at 1-800-421-1404.

My plasma tv switching off byself

Sounds to me like your internal cooling fans are not working. Try placing a fan behind your tv and seeing if it stays on longer. If it does then you'll know it's a problem with these fans. Not expensive to fix but not easy to do either.
