Re: KONICA MINLTA C250P (laser) all prints have unwanted vertical CMYK lines

I've*been doing more test prints and the various PURE cyan magenta and yellow vertical lines seem to be random not appearing in the same place and interestingly cover the entire length of the paper, while some faint (mixed with subject color) lines only appear where there is an image. So I no longer think it's a wiping blade issue on the image drums.

Hello I'm a rookie tinkerer hopping to find some knowledge about these big color laser printers and copiers.

The specific model I would like to fix.
KONICA MINOLTA C250P this is the printer only version of the full office photo copier. I have a one of the full office copier version for part too (that one gives an error for the yellow laser).

Re: WACOM CINTIQ 24HD DTK-2400 no power.

Thanks for letting me know about the data codes, I've been wondering about matching ALL the numbers on other burt mosfets and the tip about the fuse.

Also if do replace the mosfet, should I add a heatsink to the upper part? or maybe stand it up and add a heat sink top the metal back for more heat distribution? I think the back part distributes heat back to the power input board, but it doesn't seem to help cool it much. I have another one of these wacoms same model made in 2012 (one year later) and the power input board and big...

hello I have a Cintiq 24 hd dtk 2400 manufactured aug 2011.

it has no power. Tested with known good power bricks. The green light on the power brick dims when connected to the Cintiq. this is a WACOM display that takes pen input for illustration and the like.

I dissembled it and located the power input board and noticed a heat damaged component. (see pic)

Re: Help! Sharp LC-70UE30U 3 long flashes + 3 short flashes.

I couldn't open up the rar service manual file it says it's not a rar file.
but the attached pic was very helpful.
my flashing code is "MAIN PWB FAILURE" (Communication failure)

The FRC board did not fix it, no surprise.
So the problem seems to be in the main power board.
there is only one big power board.

replacing the power board should fix it this time right?

Re: Help! Sharp LC-70UE30U 3 long flashes + 3 short flashes.

Unfortunately the "power button reset" did not work.
I went and ordered the FRC board. I get the same blink code with the FRC board disconnected (no screen logos on any screen activity with it disconnect of course)
I don't even know what FRC stands for just taking a chance.
I will report if it fixes it.

Hello, I'm new to this forum. I like to tinker with Sony electronics, I have been lucky trouble shooting sony stuff, But I can't find much info on this Sharp TV.

The problem; plug to power>white led power indicator light is on>it turns on to the red Sharp logo>
then the android logo is displayed, lit fine then the android logo brightness varies, then lit normal, then the tv restarts and does the same startup logos over and over for 5 times then it turns off and the power indicator light flashes the trouble code 3 long blinks plus 3 short blinks .
