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)

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.

My sony Sony PFM-42B1 blink 5 times

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.
