Pentax ME Super repair & common faults
Excellent coverageThe Pentax ME Super, launched in 1980, is a compact electronically controlled 35mm SLR with a vertical-travel metal shutter and an all-LED viewfinder readout in place of a needle. It replaced the ME's simple auto-only operation with a push-button manual override, and it is that button-driven exposure system, together with its dependence on battery power, that decides most of what goes wrong with it now.

Common Pentax ME Super faults
Pentax ME Super manual mode buttons don't respond
In manual mode the shutter speed is set electronically by the up and down buttons rather than a dial, and that switching is one of the first things on this camera to wear or corrode. A failure sticks the readout on one speed regardless of which button is pressed, or makes it respond only intermittently. Worth trying fresh batteries first, since low voltage can mimic the same fault, but persistent stickiness points to the switch contacts themselves.
Pentax ME Super LED viewfinder display not lighting up
The ME Super shows exposure information as LEDs beside the frame instead of a needle, so a dark or flickering display usually means the meter circuit is losing power rather than the shutter having failed outright. It is worth swapping in fresh cells first, since exhausted or corroded batteries produce exactly this symptom. A display that stays dead on good batteries points to the metering electronics or a poor internal connection instead.
Pentax ME Super shutter speeds inconsistent or wrong
This shutter is timed electronically, and its fastest speed carries a tighter timing tolerance than most cameras of the era, so it tends to show drift before slower speeds do. Frames that come out lighter or darker than the dial suggests, or a speed that measures differently to what is set, point to the shutter block's internal timing rather than anything an owner can reset from outside the camera.
Pentax ME Super mirror slams or bounces loudly
A heavier than usual mirror return, sometimes with a visible bounce in the viewfinder image right after the shutter fires, points to the mirror damper losing its cushioning effect. That damper relies on a friction pad that hardens with age, so the mirror is no longer being slowed on its way back down. It rarely spoils exposure on its own but is worth having checked, as a hard-slamming mirror wears other parts over time.
Pentax ME Super self-timer or winder gives a wrong first exposure
When the shutter fires by self-timer or an accessory winder rather than the button, a wrongly exposed first frame usually traces back to the camera's main switch not closing cleanly before the exposure starts. That is a switch wear issue rather than a metering fault, and it typically only shows up on self-timer or motorised shots, not on normal handheld releases.
Pentax ME Super ASA dial won't click or feels loose
The film speed ring under the rewind knob uses a spring-loaded index to hold each setting and to trigger the exposure-compensation warning light once it's moved off the standard position. A ring that spins without clicking, or a warning light that fails to flicker when compensation is dialled in, usually means that index has slipped or worn rather than the meter itself being at fault.
