Re: 7834 Missing Trace

It's my turn to be the idiot! I had forgotten that the readout is still working. If the readout is in the right place and in good focus then all the high voltages are in good order and the X and Y amplifiers are working OK. You then need to check the sweep and unblanking signals are getting through so I would still say, turn the readout off completely, and tweak the grid bias. Beyond that a second scope really would be an asset.
