Question about Televison & Video

2 Answers

I have a Samsung HL-R6868W LCD TV. When I first turn it on it works fine, then after a few minutes the picture is garbled. I do not see any vented or blown capacitors, and the fan in the center on the back of the set is spinning (looks like a computer CPU cooling fan). I was told that the unit has a self test feature, should I use that, and if so, how?

    it seems to me that it must have something to do with cooling. With the back off and the override switch taped on, the tv has run for a couple of hours.

Hi


Thanks for using FixYa. From what you have described it seems that you might have a backlight issue with this TV set. It could also be due to the inverter circuits for the backlights. The inverter is the power supply source for the backlights. There could also be a screen driver problem; if it is then you have to change the entire board. All this is only recommended if you have some kind of expertise for checking the internal circuitry of the TV as these units have high voltages running even when the set is switched off.


Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

    If that is the case then you'll need to check for swollen capacitors once again maybe the issue could be with them. Please do accept the solution if the issue is resolved or else revert for further assistance.


    Thanks

Are you sure that is the correct model number? I am not finding much under that number there is a 6767 though. I would consider getting the service manual for the television if you are attempting any type of repair or service yourself.
Thank you,
Lee
