Question about Samsung LN-T4665F 46 in. LCD Television
Hi there, after getting my main board replaced under warranty i still have the same problem approximately twice a month. When changing between channels the tv stops responding. The channel number still scrolls up and down on the screen, but the picture stays black with no sound. Does it in either ant or cable input. Can't even turn it off with the buttons on the tv. I have to unplug it and plug it back in and it works fine. The warranty guy did no troubleshooting just r/r the main board. He said there are only 2 boards in this tv, a power supply and main board. Ever hear of this problem before> Thanks in adnavce for any advice, Kirk Johnson
Ok, There are well three boards in this set that would influence such a
behavior. The culprit is the Key Pad Board. It has what is called a
leaky switch. This then locks up the Microprocessor. This will result
in the set operating like a ghost has the remote.
