I have a samsung model #UN60EH6050FXZA which is coming on but has no picture showing or sound. Only a blue screen. I have replaced the main board. The power supply voltage checked out & the back lights are working. Any suggestions would be greatly appreciated..

Re: Bad luck
Did you check T-CON voltage?

Re: Bad luck
It has integrated T-CON into the LCD panel assembly.
Do you know the history of the TV?
This TV has T-CON/TAB bonding boards on the bottom edge of the screen whuch usually get damaged by the clean fluid when people spray the cleaning liquid on the screen and the excess liquid drips on to the T-CON/tab bonding board and causes the damages.Never stop learning

Re: Bad luck
I haven’t done anything to the tv since putting the mainboard in & checking the power supply board. Once it powers on nothing works. The remote will turn it on but the volume nor channel buttons doesn’t show on the screen. Nothing shows when I press the buttons on the tv either.

Re: Bad luck
Look to see if you do have 12VDC on both ends of the SMD fuse on the integrated T-CON board with ref to chassis GND.Never stop learning

Re: Samsung UN60EH6050FXZA no picture or sound Only a blue screen
something fishy here... seems some are "talking" about two different things. One says the tcon/ tab is integrated into the panel (which I believe is correct based on the posted picture) BUT the poster then says he replaced the tcon with no better results. This can't be THE tcon as there is no way to do the tabs. Hence, someone isn't on the same page.... and thus checking for 12v at the tcon potentially isn't being done correctly.
