My plasma tv, panasonic th-42pa20, just shut down last night.

Resolved Question:

My plasma tv, panasonic th-42pa20, just shut down last night. The power light blinks 12 times. The set is was manufactured in 2003. What is wrong, and is it worth having it repaired?

The 12 blinks is the 'error code' from Panasonic. Your particular error code indicates that the H board has a problem.


The board itself will cost around $50 - You can purchase this from the link below if you like:


With a new board in hand, and a little bit of time, you may be able to replace this yourself. If you feel uncomfortable doing this, it should take a local repair tech about an hour's labor.
