Re: Denon AVR-X1000 MCU Shorted

not sure whether you can... but in the DC detect / protect /activate circuit at the bottom of the main board diagram, there is a jumper (j5675)... which appears to bond the surrounds detection to the...

Re: Denon AVR-X1000 MCU Shorted

have you checked the diodes in the connection jumper "pack" d5701 at the power input area. Perhaps the +B is shorted, resulted in a higher incoming +B causing a "differential".

Re: Denon AVR-X1000 MCU Shorted

OK... I see the "soft start" function for the pre-amp that RJ is alluding to... :-)
maybe doing some simple resistance tests at each amp (strategic / accessible points) and compare the results to...

Re: Denon AVR-X1000 MCU Shorted

can you also check the input powers at cn503... just for comparison sake at the "source". I still think your "negative observation" is a good clue.

Re: Denon AVR-X1000 MCU Shorted

One question, where did you measure the +B / -B values that you reported? I am not sure I understand RJ's comment about the q5702... if I read the schematic right, it is dealing with the -B side of...

Re: Denon AVR-X1000 MCU Shorted

I was just poking around with interest. don't know anything about receivers much more than recent efforts on a crown and onkyo, but I do have a couple of denons, hence my interest. I was looking...

Re: brother hl3040cn color laser... output gone to worse :-(

I got a new reman drum in for the black. It has corrected the "fogging" even on first print although a test of tomorrow might be the confirmation. Thanks for the hints, comments and SM as I have...

Re: brother hl3040cn color laser... output gone to worse :-(

this was a replacement for my old monochrome but it hasn't been good. I am not really into collecting / reworking although, at this point, I am stuck between two points, give up and cycle for parts...

Re: brother hl3040cn color laser... output gone to worse :-(

tried a 10 page print out of basic black text / diagrams. Attached, you can see the first page along with the 10th page. As you can see the "fog" seems to disappear as the pages are printed. ...

Re: brother hl3040cn color laser... output gone to worse :-(

new toner cartridge didn't solve anything. :-( perhaps the drum has an issue. Attached is the printout from a plain black text file. Its about the same with either cartridge in the unit. ...

Re: brother hl3040cn color laser... output gone to worse :-(

Re: brother hl3040cn color laser... output gone to worse :-(

I am not clear on the terminology :-( The roller that is outward from the cartridge that "touches" the "exposure" drum (that has the optical sensors on it)... is that the "foam roller" that you...

Re: brother hl3040cn color laser... output gone to worse :-(

yes the magenta likely needs some attention (likely low / getting low). The conductive roller (transfer roller???) is with the toner cartridge, right? it is the roller that gets "biased", right? ...

Re: brother hl3040cn color laser... output gone to worse :-(

thanks. I switched the toner/drum "pair" from the black location with the cyan. when I do that, a "blue print" (ie. text) which uses the cyan location / now the black, prints a relatively good...

Re: brother hl3040cn color laser... output gone to worse :-(

OK... I don't see it in the driver (mac) so perhaps some default somewhere. It still seems strange that an assembly moved from one area (slot) to the another, changes its output characteristic so...

Re: brother hl3040cn color laser... output gone to worse :-(

Re: brother hl3040cn color laser... output gone to worse :-(

You are probably right.... and I wasn't very observant as there is a similar window on the opposite side of the cartridge. So there are two "windows" on each cartridge along with sensors and / or...
