MP2 Display Fading

[MarshallJMP]

Well the ones i sell work fine when you ground the pin.Problem is they are obsolete now so i'm searching for a replacement and i found one from another company but if you ground the pin (contrast) you can't read it.This one needs 1.2V to get a good contrast.So i will need to modify it so it will work and i have a 1/1 replacement.
I was thinking of putting a pot somewhere but i gave up after 5 hours of figuring out.

Hey MJ, which pin do you ground ? :dunno:

[MarshallJMP]

The contrast pin.

[tomy]

you mean the contrast pin... and Bob's my uncle ?

[MarshallJMP]

Ah you have an uncle called Bob? ;D

[tomy]

Argh... You (really) got me ! Anyway, i've tried to locate the contrast pin...better go tiling

I give up looking for my pot way quicker than 5 hours

There's not much spare real estate in a MP2

[MarshallJMP]

Nope there is not,and the pot is not so important,once set.So it's not worth the trouble actually.

I think I know what you're saying ...

hour 1 - look in all the obvious places
hour 2 - look in all the less obvious places
hour 3 - phone your friends for clues (especially the practical jokers)
hour 4 - blame the missus for over enthusiastic tidying
hour 5 - question own sanity, did I really smoke it all?

But all is not lost ...

hour 6 - it's right in front of you on the lounge table, and it hasn't moved from where you left it the night before :facepalm:

hi everybody, So I guess the only way to fix your mp2 screen is.... replacing it ! now can watch it from everywhere below, above, to the left and to the right !
In fact, it's only unreadable when mp2 is off, and that's fine 'cause at that time ... I don't need it !
