I've had this tv for awhile now and it's been very good . but lately it's been losing the pic after it's been on for a while it looks like a heat build up problem.
i shut it off for a while then it will work again.
i still get the sound so i know everything else it working ok.
what i need to know is where to get a manual to figure out which board it is. and then the part number.
if i can replace the part without calibration or special tools then hopefully i can do it myself
Thank you in advance for any help.....
