I purchased an inexpensive TI 99/4a only to plug it in and find that it doesn't work. The t.v. screen does clear (to a sort of murky white), but nothing happens. (a) I've checked the power supply and it's voltage output is o.k. (b) I've tried two dif- ferent RF connectors, and neither change the situation. (c) I have pulled the back off and cleaned the cartridge port with an eraser. I note that the speech synthesizer port is a gaping hole. Is there supposed to be some sort of null connector in there when a speech synthesizer isn't hooked up. Could this account for the problem? I'll appreciate any suggestions.

It is just an edge connector. Pull down the plastic slide for dust. It looks like you have a serious problem. Unless you have a lot of time and proper equipment I suggest that you call 800-TI CARES and they will tell you how to trade your unit in for a reconditioned one with 6mos guarantee for 36.50 . I beleive it is worth it for I have spent many hours trying to fix mine for a system crash problem w/out success.
