Good Luck,

Lou Bruno

Thanks! I'm less concerned about ordering one now... being 3 hours from the closest dealer, I would have to dedicate a day driving to and from just to fix a stuck pixel before a shoot.

Thanks Bruno - much appreciated!

I don't need it just now, but does this work on the HM100, anyone know?

Maybe we can post this as a sticky?
Simon, it doesn't work on HM100- you'll have to send it in for service!

Hang in there. I will get the menu sequence for the 100 if it is available....takes me awhile to figure this out...but I will try my best.


CHRIS-Can you make this thread a sticky?

Dead pixel
 

When accessing the advanced menu the camera seems to automatically detect the dead pixel(s). I couldn't enter the menu line 'pixel compen det' but after leaving the menu the dead pixel was gone. Dead simple! Maybe when there is more than one dead pixel the procedure is different?

It is different, but when you switch on the focus assist you see the dead-pixels highlighted.
That will help you to detect them.

Lou, many thanks. But no hurry – I don't have any dead pixels at this time but thought it might be useful for people to know if it exists. regards simon.

Every fifty operation-hours double the dead pixel, now I got over 120 hours of operation, today I see a new dead-pixel - same procedure then two month ago. 70 hours without a new dead pixel, but today I shot quite 4 hours nonstop and a new dead-pixel is born.

I think the CCD isn't quite good enough. Next time I will post a picture with the detected highlighted dead pixels - helpful is to use the focus assist -so you can see easily the dead pixels.

Remember it's not hours of use how you get them. They are being hit by xray and other radiation from space. Most cameras are about half resolution and have so much stretching and pixelshifting as well as masking so you don't often see these problems. Higher elevations and closer to the poles you get them more often as well as durring solar storms. So if you are working or at least traveling near the poles (north and south) be prepared to do it more often. I would try to eyball it every day with a monitor before you start, but that might be overkill.

I don't live in the polar region (in the south of Germany - Bavaria), I don't go by airplane,
only by train, heat will be also responsible for dead pixel, because the 3ccd (each build of
two ccd's) warming up the Cam after some hours - and heat causes dead-pixel.

The last 70 fanhours I don't see the dead-pixels, but I see it today during a shot with 720p24, undercranking and slow-shutter. And I work four hours without a rest.

But I know it from other cams, is it a problem also on CMOS (?!).

Another thing is that the fan-hour that's shown in the menu, is less (in hours) then I really shot with the cam.

Sorry for digging up this older thread, but I have a question about getting in the advanced menu of the camera.

I've put the HM700 in the 1280x720 and 60p(HQ) and switched it off.
But the next step is a bit unclear to me. Do I have to turn the camera on while already pressing the display button and keep pressing it until the camera is completely powered up or do I have to switch the camera on and immediately after that press the display button briefly and then follow the next steps? I've tried many different combinations, but so far unsuccessfully. So I must be doing something wrong.

Hi,

Press and hold down the display button and then power up.

Likewise press and hold the focus assist and then press the menu button.


Worked for me, hope it does for you

Thanks Mick, will try it out!

Re: TIP: Fixing Dead pixels on the JVC GY HM700
 

One more thing. Don't try to use the focus assist button on the top of the handle... That one will not work. You must use the one on the left side right above the "User 1" button...

I tried it..Duh... Works when the right buttons are pushed..

Had to use this today. Day 2 of shooting a feature documentary.

All fixed now!

Just wanted to say thanks for posting this Lou. When I noticed it, I knew EXACTLY where to go, and yes Chris..This should be sticky!

Cheers!

This has happened a couple of times with my camera and it seems to be triggered by heat. The first time we were shooting on a factory rooftop in Dallas in the summer and the second time, again on a hot summer day, I had the camera in the trunk of my car and the start of the shoot got delayed a couple of hours. It's pretty much impossible to see, either in the viewfinder or on the LCD screen, so I didn't notice it until I got back and started editing. The good news is, the videos were both web-videos and after compressing them it's pretty much unnoticeable, and thanks to the post on this thread, easily fixable. Thanks, to everyone in this great community!

Re: TIP: Fixing Dead pixels on the JVC GY HM700
 

Ok guys I am in the advanced menu.

scrolled down to :

PIXEL COMPEN DET: next to that it flashes "CANCEL".

if I press set it goes out. If I hold it it continues to flash.

I have done both and the pixel is still there.

I am in 1280x720 60p (HQ).

I have a shoot in the AM 200 miles away leaving at 0530 est.

EDIT: I did not know that while the flashing "CANCEL" is flashing you have to toggle down or up to get it to say "EXECUTE". I figured that out and its gone and I am good.

Someone needs to update the procedure. even though I feel stupid...I wont be the last person to get to that point. Could be very frustrating if on a shoot with no time.

Does anyone know if this pixel fix method will work with the GY HM750 Camera? A dead pixel popped up on my camera yesterday.

Thanks,

Mike

Digging up the old thread again! I had what appeared to be a dead pixel or 2. Followed Lou Brunos script (he had a script for the old GY-DV5000 as well and it worked as well so I trust his scripts) and of course I forget to scroll and press EXECUTE. After sitting there for about 5 minutes I checked here again read the ENTIRE thread and of course felt like an idiot. Scrolled to EXECUTE, BAM! 2 minutes late bad pixel(s) gone! Thanks Lou!

Re: TIP: Fixing Dead pixels on the JVC GY HM700
 

Mike, it's a different procedure for the 750 and here's the thread with the relevant info.
Take note of who the poster with the cure was :)
