The error indicates issue with the power supply and the deflection stage, Check first the cable. If you plan on troubleshooting this yourself check first the warranty. Inspect the power supply circuit if there are leaking capacitors. As for the deflection stage I would recommend a technician to have this checked.
When a Sony TV flashes five times, that means that there is an AKB circuit fault. This means that there is something wrong with the video. Try first unplugging power for few hours, if that does not work, call a technician, as several IC and components must be tested and eventually replaced.
Hi I have found what goes wrong in this screen! if you take it apart and email me i will send you a photo of the different things to look at for ! i have spare parts if any of your problems are not the same as mine!
According to the Sony Service Manual for the PFM-500A3WU, 12 22 means
either the Plasma Panel has failed or the Power Supply has failed. 12
means "warning decrease of panel high voltage" and 22 means "warning of
decrease of middle panel voltage".ve had a look on other forums and someone as narrowed the 12/22 code
down to the (ic102) its only outputing 5volts its something to do with
the (b+ power supply)
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.
Where to get any kind of parts.
The followin' link shows the discussion group.
Please give us some time to startup the group.
So don't give up any hope ;-)
