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... -
I found another post on this site the other day which has been very helpful in troubleshooting this issue I am having with my tv. The left half of the screen is dark, and the other half is VERY slow to generate it's image - and it only generates part of its image at that.
Based on this yt video, I have narrowed it down to an issue (short?) on the left side of the display, somewhere in the system of ribbon cables.
when I remove the bezel and the rear cover, I can get the image to display correctly by manipulating the ribbon cables on the left side which connects the left lower display... -
Hi All,
I have recently purchased a faulty Sharp Aquos 40aj6ke which turns on and has backlight but has no sound or video, the person I brought it from told me he had changed the main board and the same fault was there.
I have tested voltages on main board and they seems ok, the backlight is at 75v, I believe this tv has 3 x 8 strips of leds which 75v would work out to around 3v per led
I think the issue is on the board that attaches to the lcd, doing a bit of digging watching videos etc, there is a lot of mention of vgl and vgh being around -8 and... -
I have a Sharp Aquos LC-80LE757U that randomly made a loud popping noise when when watching TV one day. We found that the fuse blew and the thermistor. We ended up replacing the entire power supply board and have also replaced the TCON board. Now as soon as I plug the TV in it lights up and has the Sharp logo flashing on and off of the screen. If I unplug the ribbon cable from the TCON board to the main board I get the 2 long 5 short error code. Any ideas on where to go from here? We've tried resetting it but nothing has worked. If we plug it in and let it cycle through the flashing of the Sharp... -
Hello.
I have this issue on my Samsung EU55JS9000T TV.
Backlight is good when the one connect box in not connected to the TV and I can launch the TCON screen test with the remote control.
But when I connect the one connect box the backlight immediatly turn off, the sound is OK (TNT source).
I dont know if the problem is from the one connect box or from the internal motherboard of the TV.
I open the one connect box (reference BN96-37087R) and all seems good, simply the Hawk-P CI is very hot after 5 minutes (~65 degres).
Is someone have experience...
