Yes. I have bought a new inverter and battery monitor. Both are new from Magnum. That is why I am puzzled.

It could be my soldering is too bulky and not all pins seated properly. Or, the pin layout is very different. I cannot tell. The pins are not marked on the original. It could proprietary. I doubt Magnum will give it out to me.
I will redo the soldering and see if that helps.
I also have two more boards shipped. If they don't work, I need to try to contact Magnum again and see, if they sell this display alone?
Sorry to hear. That's what I was talking about with the different controller chips on the PC boards. It is probably a different controller that doesn't speak the same language as the one Magnum used. Hopefully one of the others will work.

I wouldn't hesitate to press Magnum for info or a complete display assembly. Sometimes it just a matter of being the squeaky wheel and getting to the right person.

Fingers crossed.......

You can release your fingers. Magnum cannot help me. They would sell the complete unit for me, but they do not offer display only replacement. Not only that, they will not give any part number, nor help, to locate a display specific to their Remote Control.
When I brought up that a display like that can be purchased for few bucks online and a new unit is between 150-250 dollars, he was not interested in helping me. Maybe he had a bad day, but he was not happy with my reasoning.
All this 1 minute conversation happened after 62 minutes waiting on the phone for my queue.
Very disappointed!

Warranty still in effect? If so the dealer that sold it to you should arrange for replacement.

No.
The Remote Control/ME-RC from Magnum is years old.
This is why I wanted to fix it myself. It is a shame that using a $10 display, the unit could be just as good as new. It is working fine, only the display is fading.
I will keep searching for the display. Maybe I will get lucky one day.

The inverter/charger and battery monitor are new. They are fine.

ME-RC50 Magnum display problem

Good news!

The latest LCD I received works. Not perfect, but good enough for me.

Here is the one:



https://www.ebay.com/itm/16-x-2-LCD-...72.m2749.l2649



There is a slight problem with it. The LCD and the main board has plastic spacers in between. The LCD has 4 holes at the corners, where these plastic columns go into. It is a bit loose. The holes are too large. However, the main board holds it enough, so you can put the housing back on, which presses down the LCD. So, it is in place and working.

The display is blue. The characters are visible but the background is not perfect.

Either way I am satisfied.

It is possible that the other boards were fine, too, except my soldering skills are not good enough. This LCD came with the pin strip already on it and the soldering looks perfect. The pins are very close to each other, so it is tricky to work with it.

CONGRATULATIONS!!! Well done! -
A bit of perseverance paid off.

The readability looks like just a contrast setting to me - I think there is actually a menu item in the Magnum settings that you can adjust it with. Try that.

If you already have messed with the menu settings for contrast, then there's likely some resistor somewhere that sets the limits of it - probably a lot of work.

I will probably buy myself one of those to keep around as a spare for mine.

Again, well done!

UPDATE: Looks like you bought the last one from that seller! Searched on "OSEPP 16 x 2" and found another seller with three of them.

You are correct again. It was the contrast. 100%. I took it down to 20% and now it is normal. Thanks again.

The ebay person had several, but others might have ordered, as well, after my post. Here is a better source. They have few more left.

Good luck.

Talking Thanks!

I had the same issue with a line of data missing. Thanks to the forum, $10 and 10 minutes later, I was back in business!

Thanks!
