Repair of LPL ET-500 Timer

[Richard Jepsen]

I set up to print this early AM and discovered my enlarger timer failed to turn on. I believe I left it on 24 hours from the previous DR session. Its plugged into the outlet the clothes washer draws power from. The washer was operated yesterday. I checked the fuse and of course its good.

The ET-500 is my favorite timer and they are pricy. Anyone know if they are repairable and what the likely trouble is. I assume a power surge was the culprit.

I assume a power surge was the culprit.

Maybe, but I really doubt it.

Typically, this kind of equipment can often be repaired by anyone with a working knowledge of electronics and some basic equipment. You may try to find someone nearby on e.g. Craigslist etc. HAM radio enthusiasts are always a good bunch to fall back on as they often enjoy a nice puzzle and most of them have the knowledge (and then some) required to work on something like this.

If I had been any closer to you, I would have gladly taken a look at it, but shipping the timer to another continent may be a little over the top.

The LED doesn't light up? May be there is fuse inside for the low voltage control board.

Funny, I had contacted a HAM group member who I have morning coffee with. Many of the amateur radio guys got their start as Air Force techs operating or repairing com or radar equipment.

I’m using a process gralab clock face unit and feel like I’m Edward Weston.

I checked around the local area for electronic repairs. Cell phone repair techs one source. No luck

Korak provided the answer. Last night I attended an Amateur Radio (HAM) group meeting. A member was able to trouble shoot and repair a solder break.

We live in a throw-a-way society. An independent repair tech can’t make a living today. HAMs were often the kid who had to take things apart to see how they worked.

Brilliant, Richard! Very glad to hear it turned out to be an easy fix and that someone was nearby willing to help out!

1. Electronic used timers are pricy for what they are and hard to find in good condition.

2. Good helpful people still live on this planet.

Excellent !

The cup of coffee, it says it all
