Flashing HP20B

I could help from germany if still needed. The display is probably leaking a little, which might be due to age (uncommon) or physical stress - it might go away in a while, or it might also stay. in some cases, the leak will get bigger. i would not bother as long as it does not disturb you. if it really is a leak (or "bleed"), it cannot be repaired.
