Re: Panasonic 65fx700b intermittent tcon problem

Caps to removes are c410 to c419 and c400 to c409

Hey my dude, I've bought this board as having the same issues and am going to be working on it over the weekend, I'm a bit of a novice but I'm okay with desoldering.

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.

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?

They are not capacitors, they are resistors.

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

It was actually a t-con from a TX-65FX600B

Hi Michael,
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.
