I have had four color blind TS 2068’s. The first one I sent to Timex Little Rock Repair Center and was sent another 2068. I electrocuted that 2068 and sent it to TS Connections in Cincinnati. It was returned to me with a memo to give it a decent burial. I ordered a second-hand 2068 from them and it was also color blind.
Bob Dyl said to send the dead one to Timex Repair Center with a check for $35. In two weeks I received a 2068 and a check for $5.05. It was also color blind. In the mean time, I was using my daughter’s 2068. Thats right, it too was color blind.
A couple of months ago, Joe Williamson told me to adjust c 18 in the RF can inside the computer. I’m a stroke victim and my coordination leaves a lot to be desired.
I got out the schematic and removed the seven screws from the bottom of the computer. Watch that the three rear screws are longer than the other four. Turn the 2068 right side up. carefully tilt the top back. The ribbon cable restricts you, but you can reach the rf can in the upper left corner. Slip a small screwdriver in c 18.
Turn your 2068 on and LOAD a colorful program. Tilt the top of your 2068 so you can insert a small screwdriver in c 18, turn the adjustment a couple of degrees in both directions until you see color.
If that didn’t work, look for the speaker. VR1 and VR2 are above and to the left and VR3 is to the left and toward the switch. You can adjust these a degree or two. VR2 adjusts the blue vector and VR3 adjusts the red vector. Then adjust VR1 which adjusts the sync and white level which helps to keep the display steady and give good contrast.
It took me about an hour to do the first one, a half hour for the second and not more than 15 minutes on the third. I’m handicapped. You should have no problem.
