Final Update: 10/24/20:
Well, my battery acid corrosion was cleaned off of my Voyage's circuit board...No issues
The battery acid issue fixed a horizontal "Zebra" line of missing pixels.
The vertical Zebra line of missing pixels was fixed by a local used cellphone seller's shop
which does microsoldering.
The ribbon cable(s) were heated up and adhered more firmly to the circuit board by the repairer cost = $40
and now, FOR A SECOND TIME, back to the repair shop.....apparently the battery acid cleaning only cleaned the circuit board but did it some damage which has led my Voyage to have a permanently non-fixable vertical line per the repair shop.
So, The Voyage 200 can be repaired if you go to the right people AND your batteries don't leak in the battery bay in the back of the Voyage 200!
One final caveat: I will ask about the Voyage's ribbon cables being removed and being able to be soldered in their stead in the future........The cell phone repair shop tried to gouge me on fixing the ribbon cable first and then told me to "buy another Voyage instead." Apparently there are too many microconnections to be soldered.
Hi again all,
So my batteries leaking acid seems to have caused corruption to the circuit board and the repair tech stopped doing further work.
He said the corrosion probably ate thru the connections making this Voyage on its way out, potentially.
The cost is $75 an hour so baby those Voyage 200's everyone...they're, so far, expensive to fix.
So battery corrosion was found in the battery tray which cause a burnout on the contact point on the circuit board of my Voyage 200.
(Don't leave batteries in the unit if you don't use it over an extended period of time!!!!)
There are also 2 Ribbon cables on the TI Voyage 200: 1 for row display, 1 for column display.
The repair tech will let me know if it's fixable as long as battery acid didn't get into anywhere else.
I managed to find a person who does repairs at the circuit board level.
I told him about the unpixelated vertical line(s) called Zebra lines and now a singular unpixelated horizontal line on my Voyage 200.
Monday, he will examine my Voyage to see if he can fix it.
He can run diagnostics to see what's up with the circuit board as well.
Stay tuned for another update.....
So.....After doing extensive research on this issue of mine,
it appears that the Ribbon cable is to blame which connects the LCD to the motherboard.
There might be a very low chance of a capacitor being out too but I doubt it as I have very, very few vertical lines or Zebra lines as they are called (so I found out.)
There is an electronics repair person near where I live who agreed to look at the Voyage 200.
I will report back here what I get for information.
