4dtv 920 picture problem

[MNcbander]

Hey, Got strange picture problem.. (ghosting like) contours images. Still have color and is watchable. This does not show on anolog or HD channels only digital channels. I have checked/swapped lnb's and cable to feedhorn with no change, Oh yeh its a GI 920 with a HD 200 decoder behind it.
Have good signals 80-90's.. Anybody else ever have this problem because not willing to give up c-band yet... Any advise would be appreiciated.

HD Channels are Digital too.
Try replacing / check the Video Cables coming out of the 920.

Thanks for reply But.... I did not add to say that I have same problem on s-video and Rf-out. Only when pass through HD 200 decoder I only have HI Def channels that dont have this problem. Dont think anolog channels will pass through s-video and decoder by nature of 920 so... I'm thinking internal to 920, maybee power supply or somthing more component level on 920? Would like to get schematic for 920 because I do have moderate electronic troubleshooting ability once again thanks for any response...

It happens when connecting Composite / S-Video to the HDD200 and Directly to TV?

have seen this problem before, but did not have a HDD200 hook inline, all digitall was ghosting an flicking to black an white, but analog played fine, simple trip to Browsville Tx cured it. now if I remember right they changed about 4 or 5 different caps in it on the repair ticket, but with you're back ground caps are easy to see when they start going bad. you also may want to call the people at ATS also they are very help full to talk too.

1Captain were those caps on the power supply board or on mainboard? Thanks..

I don't think so. when they come back from World Wide they just list the parts that they have replaced, not in any detail "like C-113 or R-244" no values or any thing like that, but would not think it would be PS related due to the problem, if it was all digital an all analog of receiving a signal like with a 60 cycle hum bar then yes.
