Hello, Today while hooking up my SRV-2000 the input meter was slammed, I turned off the unit and turned down the input. When I turned the unit back on the display wouldn't work and the unit no longer passes signal. I could smell something burnt (maybe a cap blew ?)
I didn't realize a unit could blow up from a +4 input (Perhaps distort if the input gain was set to high but blow up the unit?) Any input would be appreciated.
Thanks for the reply. I am thinking something in the power supply blew, but the bypass function (and the bypass led) still work. I looked at the schematic to see what would have to blow to allow this... Guess I will just have to open the SRV up and see...
Most power supplies have multiple voltages, so one may still work when others have failed. This is common with devices that have, say, a separate voltage for LEDs and relays etc. So you can get that "lights are on but no- ones home" sort of thing.
yes, I noticed the bypass switch, but I thought it strange that the led for the bypass switch still worked. What I can't fully understand is how an input (+4dBu) could cause a failure? The input meeter on the SRV was in the red for a brief time but I have never seen a piece of gear fail from this..
I had an SRV2000 which had a fault in the power supply where it put +15 onto the +5 rail and wrecked the eproms. The fault was in the pcb in the middle of the power supply, a cap failed. Check that you have all power supply rails at the right voltage.
I just bought a broken SRV-2000. It had a bad tantalum capacitor on the analog board that shorted the -15 rail to ground and blew a fuse. Losing the +15 or -15 supply (for whatever reason) can cause the input meter to light up.
I haven't replaced it yet, I just found the problem a few minutes ago, but I'm hoping that will do the trick.
Edit: yes, that was the problem, it works great now.
If this is the small inverter transformer used to power the display, I had one fail, went around in circles for a while, and found I could do without the centre tap I think it was. The display was showing up very strange.
