My Pentax MG has not used for many years. I tried to checked for its functionality and work just fine, but I saw strange object in the viewfinder. It's like drop off a piece of metal-plate. I tried to find a service shop how can repair here but come out w no result. So, the only way is DIY, but how to open the top plate ? Many thanks for the advice.

Re: How to open Top-plate of Pentax MG
Dust speck on fresnel lens, has no effect on print quality. But it is annoying. You can get a can of compressed air at any photo shop and try to blow it out of the way, just be VERY careful you don't hit the shutter blades. Point the air only in the front by the lens mount.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Your old Pentax lenses uses the Pentax K mount. The current Pentax digital SLRs all use the same K mount so the lenses will fit on them. You obviously won't get all the features available on new lenses, such as autofocus, but they should all work fine.
It almost certainly is due to sticky dried-out lubricant inside the camera. If the camera has never been serviced then it's been drying out since at least 1984 when Pentax ceased production of the ME Super.
It probably just needs a professional CLA service (Clean Lubricate Adjust) which will then keep it going for a few more years. It's also worth paying a one-off fee to have the foam light seals replaced as they will be on the way to becoming a corrosive black goo by now.
Although most 35mm SLR cameras are near worthless, a recently serviced and foam replaced ME Super will definitely be worth reasonable money. Still not quite as much as you'll have spenton servicing though so only get the servicing done if you intend to use the camera for at least a year to get your money's worth.
DO NOT try to take a cheap shortcut by squirting WD40 inside. You'll instantly ruin your camera.
By opening, do you mean the back cover or the top cover?
after rewinding the film opening the back door will reset the counter. if it does not reset, try firing the shutter with the back door opened a few times. this counter is mostly plastic.
with the back door opened try taping the top cover over the counter to free the counter gear.
if it still wont reset the top cover will have to be removed and the counter repaired.
there are no new parts available for this model Pentax so a good used counter could be expensive.
if you take the top cover off, usually the pointer plate on the right side of the counter is rubbing on the counter preventing it from resetting.
Pentax ME Super was one of my favorite camera, small and clean shutter release. But it has been about 25 years since it was manufactured. They happen to use rubber break within shutter unit and as any rubbers, it started to deteriorate and melt between the shutter-blades. This prevents the complete cycle of the shutter and jams the winding. You may be able to unjam the winding but eventually you have to overhaul the shutter unit. Overhaul charge is around $100 in US repair market. -James
No, you won't. Open the back and look at the hinge of the film door. There is a small screw near the top that sticks out. push it down with your finger to release the upper door pin. Your light leak is likely coming from that area too. A bad seal on the hinge is the usual suspect.
Hello igby Slocumb, As I recall, this was Pentax's way of mating electronics with mechanical cameras and the success rate was quite good. The only problem with the Pentax Super Program was the rather complex electronic circuit board. Your canera could have bad batteries, or batteries with too low amperage therefore no electronic shutter, have a short in the wiring, etc. You would need to do a shutter circuit check using a benchtop AC/DC power supply to exclude the batteries. Wow - really expensive and time-consuming = complete stripdown and repair. The camera is over approximately 30 years old making it a classic. It is no longer in production meaning parts need to be cannabalized from another old non-working Pentax Super Program. The cost of repair would exceed the value of the camera. Look for another good used model or move on to a Pentax DSLR (digital SLR) camera as your tool. Sorry I couldn't give you a better answer on how to fix your problem.
the shutter locking lever is sticking. time for a clean, lube & adjust.
i would take, or send this fine rugged camera to a reputable camera repair shop, have an estimate for a cla.
This model pentax is made with very little plastic and will last a long time with an occasional cla.
Take lens off to check the lens/light-meter coupler situated inside the lens mount at the top part of the mount at 'one o'clock' . First see if it moves freely ,clock wise. Then -with the lens off- look through the view finder while you activate the coupler : moving it should make the l.meter lights move up and down. If you are not getting any joy the connection between the coupler and the board needs re-soldering ( dry joints ) : remove top cover and resolder two blue wires on left hand side of the board . This should do the trick.
