Panasonic TC-P50U50 Mainboard Problem 14 Blinks

[dcapper]

I was given a Panasonic TC-P50U50 with 14 blinks. I did all the checks on it and there was no shorts. I reset it holding the power button and tv fired right up. Here's the problem. The only input that is work is the antenna. The HMDI's or the component are not. If I try to scan channels it reboots. Could it just need a firmware update? Or is most likely the mainboard is fried? Also, could someone help me with the suffix please?

I don't think a firmware update is going to remedy that problem. That board suffix is 'UA'.

Shopjimmy shows a couple alternatives as compatible. UC and UG.

Thank you. I can understand the older shorting points for the suffix. But I have no clue how this one works. There's lots of these boards on eBay. I'll order one.

I ordered one from tv parts today. Got a sweet deal with 2 fedex shipping. Paid $49.01. I'll update once it's installed.

Good deal! Hoping for a positive update once you get it.
