iam thinking my sammie is toast. to many hot pix. this is a bummer . i even ran a fan on it. as some of you might remember the mod i did last year. fan was in the case itself. also it has scan lines popping up now and again.. i moved the mount the dots stayed put. so iam 98% sure there toasted pix.. www.facebook.com/phil.quandt/videos/944422518942062/?pnref=story

Phil, they look more like warm pixels. And those black intermittent lines seem like interference lines. Can be fixed by making sure Power cables and data cables are separated, or that the cables and connections are in good condition.
I removed the cooling from my Sammy 4000 and now it has warm and hot pixels all over. Looks like brightly coloured confetti, and I mean about 200 of the pixels!
It proves the difference cooling makes. Cool your sensor somehow and it should improve.

ok sounds good. yeah somewhere on here i think.. was some images from after the fan mod. i placed it on top toward the middle of the case.. ill have to try a 2nd one.. i have some ferite not sure if spelled rite.. but these ferites lock around the wires. i use them in ham radio. ill try them on the video wire see what happens.
hopefully it helps.. worse case i guess i could made use it on the street to watch the front of the house lol .. its purfect when its bright lite lol ..
was hoping to maybe use it as a guide cam. with a cam lens on it.

yah i gotta do some testing. the cam hasnt had that much use. so makes me wonder.... if you look back in the gen area i think .. or even here. i posted some images of the fan mod i did. i drilled holes in the front alum that holds the ccd board and len. and the fan blows into the case.
it was fine for the time i used it. so no idea why wheres whos it happen.. turn it on one nite and bang. not a big issue i got 2 dslrs maybe ill save up for a mc down the road.

For cooling the Samsung it works better the fans sucking out the hot air ..I done a lit of testing on this coupke of years ago..never had any probs my camera runs at ambient temp..camera uncooled runs 6 degrees hotter on a twenty minute test. try a new av cable..the sammy is usually bomb proof.

Yep, totally agree with davy. Suck the hot air out, not blow more air in. If you are blowing it in, have another fan sucking the heat out or the 'blowing in' fan will just blow the heat around the inside and make it even hotter.

Thats my idea for the phil dyer mod..spoke with uncle john a couple of weeks ago on this..looking to fit a small high cfm rated fan to bottom of camera body and a larger slightly slower fan to the top ..I wanted to create a vortex type flow through the camera casing..heat will dissipate through larger fan hole

will its toast. the second i turn it on the pix are there... i dont think they would show up the second you turn it on if was heat issue.. maybe few seconds or mins later. but instant. i guess i could still use it for luna. it seems they show up at around 64x and above.
sort of figured was goin to have issues with this cam.. when i got it the guy had 2 of them. he kept one. this one probley had it from the start. or he seen something and sold it..
can use it to collmat my sct so its ok . it still has uses.. so luna and collimation of sct good. dso'ing no go.. grrrrr

Looks like you now have yourself a good Solar/Lunar/Planetary camera. Just not DSO's.
