i have tried different power outlet and still no change the jumping comes like 3-5 minuets from starting
but have tried to change from 1080p 50Hz to 1080i 50Hz the picture is steady and no jumping
the pj is new at my home and my biggest concern that the machine is ok and no problem with the pj?

AnalogRocks thanks

first i will take your advice and will buy a thermometer that can check the temperature within the pj it has a very thin wire that can be placed inside the pj and this will probably be helpful for the future

second i don't think this is the problem because

1. there is a direct flow of air from my air conditioning pointing at the pj about 1 meter from the pj
2. how come is doesn't happen in 1080i 50Hz only at 1080p 50Hz

thanks
shay

One other thought: (I've seen this in the old 800s, not the 1209s, but it could be an issue): There are two V hold pots on the V board, near the middle of the board I think. I've seen the odd 800 lose a bit of V sync that can cause jumping. All you need to do is turn the trimpot(s) VERY slightly, and the pix will be stable again.

Thanks curt
the CRT pj is a new baby at my home theater and i'm not a technician so please i will be very happy if you could direct me with a picture where should i turn a bit the screws
do you think that this is the issue because it doesn't happen when the picture is in pause mode and there is no movement and also it doesn't happen at 1080i rez only at 1080p
theres a good friend here in israel that has the moome card may be this will solve the problem?

i have heard about another input cable that can be used instead of the RGBhv
should this solve my problem before i'm doing any search to get it?

You do realize the picture centring circuit only works on the YPbPr/YUV output of the HDFury2 right? There's no centring on the RGB output. It could be a centring issue.

It might work better with an external box to center things like an Extron 202/BUF200/RTC2200/Box1040 etc....

well here is something strange

when i use the HDFURY2 at 1080p 50HZ all the problems are starting like jumping
and when i move to 60Hz the picture is ok

can someone have any explanation to that

let me add that i'm from israel and here we have 220 AC at 50Hz

Does the HD Fury2 even support 1080P 50??? I don't really know.

50hz porch size combined with the left shift from the HDMI is probably making the projector mad. I wonder also if the 1209 will sync to the + positive sync signal?
