Sony PFM 500A2WE 12 22 error code

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.

Sony PFM-42V1N

The display processor, and or the panel itself, and or one of the ribbon interconnects, may be the fault. This can be rather expensive to service. You can send the set to a Sony service center for a quotation. You may find it very expensive to service.

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)
