Intermittent Power

Recommended Posts

My power is going out about every other use on my TI99/4a. The power comes on, I use it for five minutes to an hour, turn it off, then the computer will not turn back on for several hours. But it will turn on again the next day, and the cycle continues. If you were a bettin' man, would you say that was an internal or external PS problem?

I didn't see anything physically wrong, but it was the internal power supply. I swapped it out with the PS board on my old, broken TI99, and it's working fine now. I think it had a bad capacitor.



I would check solder joints really good for any that appear cracked and need to be reflowed.
