Ok, so my tv cut itself off about two weeks ago and started clicking immediately after. The video worked fine for approximately 2-3 minutes before this happened. I have a background in electronics, so I thought that I would figure this out on my own. HA. Well, I have replaced every board on the back of the tv except the video board. I cannot find any noticeable traces of a destroyed component. When all boards are connected, the relay clicks 5 times and shuts off. With the x-main disconnected to the y-main (they are daisy-chained) the tv powers up without video or backlight. However, the strange thing is that the voltage on the power supply VS is at 11 volts. It should be 207. The VP is at 0 volts. This voltage steadily drops to these from 207 (VS) and 58 (VP).
Now the crazy part, if I disconnect the ribbon cable from the main logic board to the y-main, then the power supply voltage and y-main voltages are correct. Should I connect the y-main and x-main with the ribbon cable unattached, then the tv still will not power on. I'm at a lost on what exactly could is wrong or where to go from here. Anybody else been through this or know where I should start?
