Check your set for coolant leakage. It is very prevalent on Mits HDreadys.

If your 4 layer Signal board - beneath the blue gun - has coolant on it, you'll have problems finding a replacement. If it's the boards under the other 2 guns, they can always be repaired as they are single layer.

A drip shed should be installed to keep the coolant off your boards.

Most of the time the Hyper Board failing is the cause of this problem. It will eventually get worse where it also affects the HD ins. Unfortunately the Hyper Boards are no longer available from Toshiba and have not been available for quite some time. My suggestion is to coast with it and replace the Set when the HD ins fail.

TV screen goes blank but power stays on


Sounds like the CRTs are going into protective blanking due to the vertical output ic needing to be resolderd. Try resoldering the vertical IC that may possibly fix the issue.

"ant A" and "ant B" inputs go black when the tv is first turned on.


Try opening that "Ant A, B" device and apply some fresh solder to all the components inside. Also you can try to by-pass that device using the connector below. One end connects the cable in and the other end connects to the circuitry inside the TV.

Black TV Screen above Channel 46


Try resoldering the tuner can's connections to the main board.
If that doesn't solve it, you need a new tuner.

Or do what all too many people do, use the VCR's tuner and just leave the TV as a monitor.

Not to discourage you, but here is an extensive thread from other Samsung owners with similar problems:

Sounds like the digital/DMD board has noise in those modes.
hope you are under warranty
