I purchased 4 of the Digital Stream digital t.v. converter boxes model # dtx-9900, two years ago. Two of the converter boxes went dead. The problem was found to be capacitor #209 on the power supply circuit board in both units having the wrong maximum voltage rating. The capacitor will go bad on every one of these converter boxes sold across the U.S. due to this design error. The repair is the replacement of this 16 volt 330 microfarad capacitor with a 25 volt 330 microfarad capacitor. The digital stream company should be responsible for recalling every one of these model units & possible other models made by Digital Stream. When the capacitor goes bad, the units l.e.d. indicator will either blink or go out. The capacitor can be visually monitored for going bad because it will start to form a bulge in the top of the usually flat cylinder. All Digital Stream DTX-9900 converter boxes will go bad over time due to this flaw which will cost each consumer between $40 & $60 to replace.
