For me it was trial and error. Originally, the TV would not come on, and would click on and off. The Red light that blinks to me would be a code to let one know what the issue is, but from my knowledge is doesn't do anything to that effect and just blinks. To answer you question, its like finding a needle in a haystack. Its a trial and error taking a piece of small sliver of tape and cover up one of the pins to see if a difference happens. If you cover too many pins, the TV falls on its face and just wont boot up. I can remember using two pieces of tape that i would move along the ribbon cable to see where the problem was. It was lot of troubleshooting.

This was my main TV for the last 6 years. I'm not inclined to throw out a $2600 TV so quickly so I'm trying to investigate the issue.
Problem
TV was disconnected from power for 6 months during construction. When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode... -
I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.
I ordered a supposedly ‘new' Tcon board this time, and... -
Hi friends,
a friend of mine gave me this TV to fix, with common SAMSUNG TV issue - damaged panel. Turning on, sound is present, but no picture. So I went directly to standard process, connecting two pads together with a wire ( see in the picture ), and then removing flex cables. With right flex connected, there was half screen working, but still no picture ( disappearing colors and similar weird stuff ) + working sound. With left flex connected, TV is restarting + working sound. I supposed, left side is damaged, so I then blocked all 8 CLK pins ( going from 0R resistors on the second... -
I have a Samsung UN58TU7000FXZC (same as UN58TU7000FXZA, just the Canadian model) with no picture. Backlight is on and sound is coming out just fine. Just no picture.
What is frustrating is that there's no voltage test point and no component labelling of any kind.
What I have found so far:
1. No voltage at pins 91-94 of the 96 pins connector CN1300 (marked 1 on the picture). This TV set has no T-CON board. The 96 pin flex cable goes directly to the right (when facing TV) lower panel board. Itself is linked with another flex to the other side.
2. Voltage...
