    HannSpree HSG1064 Turns on, video for 5 seconds and then nothing

    So I have a HannSpree HSG1064 monitor/tv. Pretty nice 100$ tv that was working great until a few days ago. It was manufactured in 2009, so I thought maybe shit caps? Looked online and it seemed like a probably cause. However, I opened it up and they seem to have ditched the shit caps and used Taicon, which is definitely a cut above the rest if we're talking most shit caps.

    So none of the caps were bad, all were fine.

    No heat damage from the circuit board by what I could see on the PSU, in fact the PSU seemed to be one of the best I've seen in a cheap TV.

    Since the PSU seemed fine as it would turn on and the audio would continue to work, the video would just stop, I'm not sure where to look? I took off the mainboard and it was capped with "GJT" branded caps. All seemed to be fine.

    What should I look at next?

      Used a 900 lumen flashlight just to be sure, no image.
      It also wakes up and falls asleep as normal as well.

        Are backlights staying on?

            Need voltages from connector that goes from power supply board to main board. Will need pin#- PIN DESCRIPTION -Pin voltage in standby-Pin voltage when pushing power button and picture of connector on power supply board.
            Format:
            Pin# - Pin Description - Pin Voltage standby - Pin voltage power on
            1 - XXXXXXX - XXv - XXXv
            2 - XXXXXXX - XXXv - XXXv
            3 - XXXXXXX - XXXv - XXXv
            4 - etc.
