FS7: Red Smear on LCD Screen

Just purchased a used Fs7 that came with a red smear of pixels on the LCD screen. Interestingly enough, if I pull up the menu it superimposes over the red pixels. It doesn't show up on recorded footage. That leads me to believe this might be fixable. Anyone seen this before? Suggestions?IMG_20171220_202152.jpg IMG_20171220_190453.jpg

UPDATE: I purchased a replacement LCD for $350 and am going to just swap it out.
 
Hang on to the one you pulled out as a backup, just in case it happens again. I would suggest what you are seeing is without a doubt ia a 'sun strike' where the sun has come through the viewfinder eye piece and burnt the LCD.

I know someone who did it to a PDW-700 color VF, ouch! They were about $10K back then. Years back I damaged one on an EX3 in about 15 seconds one day as I adjusted a wireless mic on the talent and forgot to turn the VF loupe downwards or open it right up. The EX one was about $500 back then so I think getting out of jail for $350 is pretty good. If you require an exploded diagram of the viewfinder for a dis-assembly / assembly guide I can upload one if required. Besides the LCD and the front and back panels there are eight layers of parts from front to back on the VF.

With my sun strike I should have known better. During my training a hundred years ago with the BBC if we walked away from a camera for more than a few seconds the instructions were "Zoom in, de-focus the lens and then tilt it down. Lastly close the viewfinder or point it down." This applied to the film cameras and the early tube cams. With the tube cameras we could get a sun strike through the lens and burn a tube. No shooting the sun back then. These old suggestions still hold pretty true even today.

I agree with Chris about sun damage. On my FS7 I put a UV filter on since I am out in bright sun for most of my filming.
 
the UV filter won't prevent as it's not a UV issue.
btw it happens more often with the Zacuto Z-Finder as it's shorter than the standard tube and the focussed sun is going to hit the LCD easier.
 
Out of interest, as it seems to be a sun-burn effect, does the yellow box (when you highlight a menu option) also 'overlay' over the red? I ask because I imagine the white menu text doesn't reveal the burn, as there are essentially no 'active' LCD pixels on the white text, just pure backlight showing through, whereas the yellow would probably still reveal the damage. Just a thought. -jason
