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

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 google.com 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 ;-)

Based on the symptoms described, it seems that the issue with the Panasonic plasma monitor is related to failing capacitors on the Power Supply Module. The fact that heating the board with a hair dryer temporarily fixes the issue confirms this hypothesis. It's recommended to replace all the capacitors that show signs of failure or have a bulged appearance, as well as any other faulty components on the board. It's also a good idea to have an experienced technician diagnose and repair the issue to ensure proper and safe handling of the components.
This sounds like the power inverter is failed.. It's what pumps up the power for the light in the monitor.
You could try unplug the sound bar from the back of monitor if you have the sound bar installed. Just a maybe..
To fix the inverter (replace) is usually better to buy newmonitor unless you do it your self.
The defective LCD Backlight inverter will cause the following symptoms:
No Display, but Power Indicate light stay on green (Or Blue).
Screen flash on and off and the power indicate light stays on green (or Blue).
Have you checked the filters? I have a Sanyo PLV-75 and had a similar problem. The normal fan would come on when the unit was first started, then after a few seconds the secondary fan came on and then the unit would shut down. Called tech support and they asked if I had cleaned the filters. I did it, and it worked great. Check the manual for where the filters are and hit them first before getting a new bulb. Hope it helps!
Hi. this is a failed power supply. the power supply pack will have to be replaced. it located on the rear side of the tower in the upper corner. its where the power cord plugs into. replace the power pack and this will fix the issue at hand.
Sorry not a solution - but I have started experiencing the exact same problem over the last month although sometimes, on switching on again, it will run for 10-15 minutes before the problem re-emerges. Initially I put it down to the v. hot weather in July but it still continues.
So I would also appreciate any solutions!
