Second opinion] Hi, Ive got a panasonic tc-46pgt24 plasma. Bought 2010. Recently, all my 3-hdmi ports went bad..cable, dvd, iTV. When i change to hdmi input, its either black, snowy or pixel purple with blurry picture. Do you think this is a main board or power supply issue? Also, TV works off antenna but sometimes have to cycle power afew times to finally get picture.

Ask Your Own TV Question

To isolate for sure what is causing the problem, does the Panasonic remote consistently pull up the MENU clearly?

menu is clear.

Okay so MENU is clear yet HDMI ports won't work- correct?

Customer reply replied 4 months ago
correct. i usually use hdmi port 1 for cable but now no good...as is hdmi 2 & 3.

Okay, then that would directly indicate the Mainboard is at fault since your MENU's are working fine, but the HDMI ports are not. The HDMI processing occurs exclusively on the mainboard (your external signal board). The TV's MENU is generated upstream so your power supply board would be fine. I'm finding the replacement mainboard for your set available at the link below:
