Airlink 101 digital to analog tv converter box
Specifically, it will power up and display the onscreen information (like which channel, volume etc.) but all channels (with THIS UNIT ONLY) give the error "No signal. They told me I can go "higher" in the V but not lower.)Īfter replacing the two capacitors, the unit powers on but it does not work. (I will note, in case it is important, that the originals were 470uf/10v but the store only had 470uf/16v ones - which I was told would be fine. When I opened this box (feeling brave having replaced a popped cap in the power supply), I saw two bulging capacitors so I replaced them. I doubted my repair of the power supply but it worked completely fine on the other unit. Initially (after my capacitor change), using either power supply, the unit flicked on and off and never got to showing a station. Remember that the Converter box itself HAD been working (when I powered it using the other unit's power supply) but now it is not working.
However I seem to have a new problem which confuses me greatly. Long story short, I replaced a blown capacitor in the power supply and it is now working! That is to say, both of my power supplies will power one of my units and that unit works just fine no matter which supply I use. Using the other power supply, the 'not working" unit would work and, conversely, my second unit would cease to work when plugged in to the questionable power supply). Because I have the other unit and the other power supply I was completely confident that the problem was with the power supply. Initially, one of the units was having intermittent power problems and finally just quit and would not power up. This has been helpful in the troubleshooting of my current problem. I have two identical Access HD DTA1030 converter boxes for my OTA TV viewing.
