Can't remove large dustparticles inside the lens. acer P1265

Get some industrial size silica gel bags and warm them in the oven. Put a couple of bags inside a large Ziploc bag with the binoculars and leave them in a warm place like an airing cupboard for a week. It there is a lot of water, remove the object lenses (the large end, they should unscrew) and shake the water out. The gel packs last forever and can be dried out in the oven before use. I have some from the mid 1960s as my dad used got them at work from rolls of copper foil that were delivered to make printed circuit board.

hi Cheryl.
Try cleaning the lens inside the drive with a q tip or something of the like or an optical drive cleaner.
You could try to take it apart and find the obstruction.
You could open it and spray compressed air into it and hope it removes the obstruction.
try getting a laser cleaning disk to clean the lens inside.
or this could be something else wrong with it.
just let me know if the above works first.

The bulbs are typically set in a small unit that disconnects from the insides via some kind of connector. The whole unit is then replaced.

code P1265 injector 2 control limit exceeded or limit not reached.

Don't even try to clean the inside of the screen on the mode indicated here, av 56p575.

If the picture is darker remove rear cover and reach up with a lens cloth and clean the three large lens---they are your light source.

What is your reason to want to clean the inside of the screen, I am able to offer advice there.

I have the same problem. All of a sudden there are plenty white dots all around the screen. As if 1/3 of the pixels are burnt. It cannot be the lamp because it is still as bright as before. It must be the internal screen or whatever. The "Troubleshooting" section of the user manual does not mention such thing.

There are two ways to do this---the hard way which is to remove the entire front screen OR

What I do is (with the set unplugged) remove the back cover of the set; you should see the three large black lens.

Most of these sets there will be enough room to get a swiffer duster up inside to gently catch and remove all the spider webs. If there is not enough room let me know and I will tell you how to remove the front screen.

Also---if you can see those large black lens---clean the dust off of them with a lens cloth or paper towel with glass cleaner sprayed on the towel.

If you can reach the webs from the back do not exert pressure when you wipe the inside of the screens---easy to scratch them.

If you have questions let me know BEFORE you attempt this.

If this helped or told you something you did not know rate this solution as very helpful as I do this here for free.

REGARDS, SD TECH

It's probably on the sensor. A spot on the lens would be so out of focus and would not be noticeable unless it was very large. At any rate, you can't clean the inside of your camera.

P1265 = glow plug #3 control circuit low.

Looks like a problem with your #3 glow plug,either the glow plug itself or the GP driver in the PCM.

This would explain the starting good one time then hard the next. I would test the glow plug if it is good there may be a problem in the PCM (power trans control module). Are you getting any other fault codes this would point to a bad PCM.

Hope this helps (remember comment and rated this) TY for using Fixya.
