May I please have it?
Also, after I changed the boards, now the tv lights up but the image looks like this. Is it normal before flashing the eeprom or did I mess it up while remving the caps?
Thank you for taking your time to post a solution.

Re: Panasonic 65fx700b intermittent tcon problem
I fixed one of these t-cons on the same model.
There's a single S.M cap at the very top middle of t-con.
Replaced it and fixed.
I found out by applying 3 seconds of hot air on the t-con just before you turn on the tv, panel will come on and stay on. Until you turn it off, then reheat repeat.
Or just Replace cap mentioned
Also 55" tcon won't work, been there

They are not capacitors, they are resistors.

Hello,
I have the same problem with T-CON board for 65FX700.
I think I go to buy a TC-Con for 55 inch.
Michaelrobbo, why you removed 4 caps?

I have a quick question though, which chip is the EPPROM? Just so I don't start dicking around with the wrong thing.
Thanks mate, appreciate the help.

Re: Panasonic 65fx700b intermittent tcon problem
Can confirm the problem was with the dc-dc ic part number sw50212 but couldn't source one it would only work when heated so was failing not the solder so to fix I got a working board off a 55inch and did an epprom swap and removed some capacitors hope this helps people with the same problem
