Repair of antenna analyzer MFJ-259B (2024/05/27)
Antenna analyzer MFJ-259B that would have been damaged by lightning
When I turn on the power, I can see a faint display, but it is almost invisible.

I'm buying NanoVNA, so I don't think I need it, but I sent an email to MFJ just in case.

I did so, and the reply came back immediately, "the LCD is ruined"!
In reply to an email.
It appears a new display is needed. $9.84 plus shipping.$25
They shipped on April 22, 2024.
This was right before MFJ went out of business.

LCD panel received
I cut the flat cable at the LCD and re-soldered it.
After replacement, when power is turned on, all letters are displayed as black blocks
The LCD now displays black, but no text.
When the power is turned on and off, the opening screen is displayed for a moment.
I was about to give up, thinking it was a defective PIC.KOA GikenI consulted with JG2TST Matsui, a "combatant.
He advised that the PIC might be alive.

JG2TST Matsui-san immediately found a schematic of the MFJ-259B, and he was very helpful.
If the "PIC is ruined, nothing should show up, if it does for a moment.
He advised me that "the resistor for the brightness adjustment may be ruined.

He really is a dependable fighter.
Replacing the resistor with a semi-fixed resistor fixed the problem!
