I spent much of the weekend opening my 99/4A, removing the cassette jack, installing F18a, placing VGA out in the place of the cassette jack, etc.
Powered on and all was good. Fun last night and was online (telnet BBS) via WiFi232 and TIMXT this morning. Left the term prog loaded all day while I cleaned and rearranged the room so I can actually sit in front of the 99 to BBS properly, aaaand.... I noticed the text on TIMXT was no longer white but a muddy color. No keyboard response. I powered off and on -- no more video output.
I can hear the TV power up, I hit 2 for FR99, can hear things as I navigate thru it and load a random cart and I see from its LED that it's loading a cart. But no video out.
I tried it on a different VGA LCD, no video there either -- so it's not my screen.
SO disappointing. Was so looking forward to BBSing in ANSI color on the TI here on my 45th birthday (today). Definite birthday downer. I really don't want to pull everything out again and open up the TI -- no energy for that again, not tonite.
Any ideas out there? Is there a chance things are not fried? I now the TI needs the gfx chip to access memory, or I believe it does. So, it can't be fully fried.
The ribbon cable is well secured, screwed into the case. No stress on it since I turned on this morning.
