DL warning displaying on the panel. it's not started

The error code "dl" is for door lock. From what I've read, it may mean you need to replace the latch assembly.

check your load distribution

There is a problem with the cardrige.

1. Press MENU # 1 9 3 4 in sequence rapidly. The LCD panel should now display TECH.
2. Press MENU, and then press ENTER. The LCD panel will display Tech Mode.
3. Press the left arrow (<) button once. The operator panel will display NEW CARTRIDGE.
4. Press ENTER. The operator panel will display [YES].
5. Press ENTER. The toner warning message should be gone.
6. To exit TECH MODE, press MENU # 1 9 3 4 in rapid succession, as if you were dialing a phone number. The operator panel should no longer display TECH.

If problem persists, there may actually be a problem with either the toner cartridge or the SCX-4216F.

Hi,

"dl"indicates a door lock error. A Door Lock Error occurs if the door cannot be unlocked. It will try to lock it 6 times before displaying the error.
Check for the following when dl occurs:

• Door Lock Mechanism broken.

• Check Door Lock/Switch Assembly for foreign objects

• Check Wire Harness connections to the Door Lock/Switch Assembly and Central Control Unit (CCU)

• Door Lock/Switch Assembly Failure

Thank you !!

Replace the fuse on the bottom of the drum cartridge.

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)
