Re: Samsung UN60FH6003FXZA

Let me just state the current symptoms. The tv is stuck in a boot loop with no leds on. If I it leave on l, still looping, and disconnect the lvds cable, the leds turn on, but no picture. When I re-plug the lvds cable, tv works perfect for 20 seconds then starts to flicker, but continues to function. If I turn it off, then on, it’s stuck in the boot loop again.

I replaced the cable because I checked the voltage at the main board, and at the tcon. I had the voltage at the main board but not the tcon. The tcon board was new.

Re: Samsung UN60FH6003FXZA

So I put the new lvds cable on. Turned on, and for the same boot loop. I leave it powered on, unplug the lvds cable, leds come on as expected, then I replied the cable back in. I now have a picture from my hdmi input, but it has a fast flicker.

Re: Samsung UN60FH6003FXZA

I already disconnected them one at a time. No change. I found a trouble shooting guide for this tv, and it pointed to the lvds cable as well. I tested the fuse on the tcon, and got no voltage. The trouble shooting guide pointed to either the main board as the problem or the lvds cable. I just replaced the main board with a new one, so I’m replacing the lvds cable. I’m an aircraft mechanic, and have some electrical training and experience.

Re: Samsung UN60FH6003FXZA

Yes, no change at all. The tv acts the same with either tcon board in, and the same when the tcon is disconnected from the main board. That’s why I’m wondering if I have a bad lvds cable.

Re: Samsung UN60FH6003FXZA

I tried disconnecting the cables to the led driver one at a time. No change. So I put the original boards back in. I had no sound on startup. So I replaced the main board with the new one, kept the original tcon board in. Now I have sound, leds still come on, but no picture. When I disconnect the lvds to the tcon, there are no changes with either the old board or new. I’m wondering if I have a short in my lvds cable???

Re: Samsung UN60FH6003FXZA

I put the original tcon board back in. Tv boots up, leds on, no boot loop, but can’t see anything on the screen. I noticed that the board on the bottom of the tv with a ribbon cable from the tcon (left side) is loose.

I picked this discarded tv from a neighbor. They said it powered up but nothing on the screen. LEDs would come on but no startup chime. I replaced the TCON, and then when I plugged in, the red light would blink, but LEDs would stay off. I unplugged the main board from the power supply then plugged back in. Leds came on and stayed on. Then I replaced the main board. Now, I'm stuck in a boot loop where the startup chime sounds, but the leds never come on. Tv has been in my garage sitting, and we've had a few cold nights around freezing. I've also tried warming up all the boards with a heat gun with...
