I've got an old TM1500 which appears to work fine except it will no longer pick up any channels (quite a major flaw!).
The receiver was working fine last time I tried in in August but it's been switched off for a few months and now it doesn't work.
On closer inspection the LNB input and loop out are both producing 24V which is worrying. Switching between V and H polarities make no difference to the output voltage.
The power supply looks OK and the voltages from it all seem to match those written on the board (5V, 3.3V, 8V, 12V, 22V). I'm no expert in repairing boxes but it seems to me it could be something on the main board that has gone, maybe even the tuner itself. I'm guessing it's probably not worth repairing and might as well just throw it away?
It may be a coincidence, but during a thunder storm in the area a few months ago the ADSL modem and an IP camera stopped working so they where replaced. I'm now thinking maybe it got to this receiver too although it was switched off (not standby) and plugged into a surge protector at the time and the TM1500 isn't connected to the LAN network.
