[QUOTE="ilpresident, post: 883606, member: 175139"] Hi to all, It's been a while since I posted anything here. As a matter of fact, it's been a while since I tried anything with my DM7020 :) The reasons are two: work and sat problems. Problems come in the form of the STB not moving my Stab HH120 rotor at all. To test, I borrowed an old StarSat with Usals and tried it. Rotor worked ok and quite fast, faster than the DM ever did. I also tuned stations from a number of satellites just to be sure and all was ok. So I concluded that my DM is at fault. First I tried flashing a new image instead of the Gemini 4.70 and installed a PB-VX and at first I thought that this had solved the problem as it worked between Astra 19.2 and Hotbird 13.0 but when I searched for other satellites, then the motor stopped on the last one searched and was stuck there. So I had to turn it to zero using the StarSat. Ended up installing an image by OoZoon in flash and an Enigma2 pcd9.0 in USB. The problem still persists. I then borrowed (borrowing time galore) a Stab HH90 rotor and tried it directly with a short cable with my DM and it didn't even turn a measly degree. With the StartSat the rotor turned without problems. So now I'm thinking of maybe having a problem either with the tuner or with the PSU. As I'm not ready to throw the towel yet, is there a way of knowing which is the culprit? Can I somehow check the voltages from the PSU? Where can I obtain an original replacement (Matsushita) other than those Chinese ones? Or shall I try to replace all caps from the PSU as suggested in many old threads on the Web? How to tell if the tuner will be kicking the bucket? Any help or advice would be much appreciated. Thanks. [/QUOTE]
