I haven't had a chance to look into this yet, but the other night I turned it on and the bottom half was black with white horizontal lines, and last night the entire screen was black with white horizontal lines going straight down the center spanning about 2/3 of the screen. I'm thinking it's gone into full tcon failure at this point. I'm guessing the caps on it would be surface mount? I do have the means to replace them now, but if it's too many a new tcon would probably be worth it.Comment

It's about 40F today and I plugged it in to what it would look like. It only had about a 1 inch bar across the bottom this time, and like before it slowing moved down and off the screen. I put a heater on the power supply and unplugged the tv to see if it would come back. It did not come back. I'm thinking of taking it inside my house and letting it sit at room temperature. I have a feeling it would work fine in normal temperatures, although that still wouldn't be a "fix".
Attached are photos of the boards. I did clean the ribbons and well.Attached FilesComment

Heating up the power supply definitely gets rid of the issue. So does this mean there's something wrong on the power supply, or bad caps on the TCON?Comment

The TV stuck at logo and cannot be turned off unless the cord is unplugged.
I was given two main boards and exactly the the same thing happens to both of them.
I have checked all voltages on the connector on the power board that goes into the main board and they all look OK.
There are no signs of damage on any of the 3 boards.
Would someone help me with a pointer to the manual? It's supposedly to be the same as E601i-A3.
Thanks! -
Philips 8200 series 65PUS8204/12 stuck at Philips Logo, it does not reboot it just stays on the logo.
It does power up when pressing the power button.
I already try the power button while plugin the plug with no result.
Also put the latest firmware autorun-TPM191E_R.001.004.100.000.upg on a MBR/FAT32 USB stick at USB port2 with no result either.
Could this be an PSU or eMMC issue ? -
I have used the search, and am stumped.
My Vizio M65-C1, Vizio logo appears for about 10 seconds then goes off.Power LED blinks 15 times then the TV powers down.
I have read through many threads on the M65-C1 including the following threads. I feel like I must be looking right past the solution to my problem:

Hi everyone,
I'm working on a JVC TV for a client that's stuck on the "Wisdom Share" logo screen.
It's a model LT-50N795 with a board number TP.HV510.PC822. I attempted a firmware update via USB, and while the upgrade was completed successfully, the TV is still stuck on the Wisdom Share screen on reboot.
Has anyone encountered this issue before, or does anyone have any suggestions on possible solutions?
Thanks in advance!

Ok so here's the story. I was watching tv one day when all of a sudden I heard a pop from the back of the tv set and rushed to unplug the set. By this time the tv already had smoke coming out the back. It was not storming or inclement weather that day to cause a power surge to the best of my abilities. When I opened the tv up, I found that the three capacitors on the psu (highlighted in red) were all bulging and looked they had exploded. I replaced all of them right away and when I went to start up the tv after the "fix" it started just showing the flashing vizio logo as soon as power...
