Re: HP LaserJet CP1025nw hangs up

Doesn’t make a difference. It needs that hard reboot in order to get things working again. Powering off and on for example doesn’t fix it either. The only thing that would make sense is that the...

HP LaserJet CP1025nw hangs up

Re: Dbx 286 repair

you need some sort of a probe, either visual like an oscilloscope or audible like high impedance audio probe of some sort.

Re: Dbx 286 repair

BTW... on the block diagram there is a 6.5mm audio jack called insert on the...

Re: Dbx 286 repair

Re: Dbx 286 repair

no unplugging anything required. Just press the process bypass button on the front panel. When pressed, a red led should turn on.

Re: Dbx 286 repair

the 7815 should have +15VDC, while the 7915 should have -15VDC. For the 7815 only having +12VDC something is already off. Either the regulator is getting loaded down, or it is bad as it cannot handle...

Re: MTS70-0512ACW going into protection

Sounds like the PSU starts up, sees a short on the output, or something wrong with the feedback, then shuts down. Post some high resolution straight shot pictures top and bottom.

Re: Dbx 286 repair

The easiest way to troubleshoot this is to inject a signal on the input, then follow it through each stage with an oscilloscope and figure out where you loose the gain. Could be an opamp thats not...

Re: First oscilloscope thoughts

a Siglent here is also more expensive than a Rigol. It may be different for the USA, but here we get taxed stiff for imports.

Re: First oscilloscope thoughts

check out Siglent, they make decent scopes for the money. 100Mhz is all I ever needed. Of course 200Mhz is better, but so far didn't need it.

Re: Yaesu FT1000MP mk.5 receive issue.

RX/TX relay RL6451 bad if it is doing that on all the bands (Tuner Main Unit). It's a sealed unit, so just replace it. Download the service manual and read page 4-1.

If it is only doing that on...

Check the second mirror that reflects to (and) the AF senor. Maybe their position changed?
