    How to fix this distortion on the display? Picture inside.

    Sorry. Just noticed that. I would try to push the yoke a little closer to the tube if you can (with the power off) and see if it will straighten it out. You can use the magnets to adjust the corners, but I would try and make sure your yoke is in the right position first.

    How to fix this distortion on the display? Picture inside.

    There are some magnets on the yoke that adjust the geometry of the tube. I would assume snce the top right is out if alignment you'll need to adjust the magnet that is in the same quadrent. (I.e. the one on the top left looking fro the rear of the tube)

    Acquired a IIfx (yay!) Issues (boo!)

    Probably a little above mine too, but just to check.How is the 5v on other places on the board? Is it just low at the floppy drive? Are you testing the voltage at the drive, header pins, or at the inductors that feed the drive? Is the low voltage with the drive plugged into the board? If so...

    Acquired a IIfx (yay!) Issues (boo!)

    Your welcome! Yeah. I would replace all the electrolytics (power supply and motherboard). Only reason i said the motherboard first is because you said everything else was working fine. It only takes one bad cap to pull a line down. I would replace all electrolytics in the system and clean...

    Acquired a IIfx (yay!) Issues (boo!)

    Don't know much about the iifx. Saying that.... it sounds like everything else is working except the floppy's 5v. I know everyone says it, but since you didn't address it in your description. Have you replaced the electrolytic caps on the motherboard? A bad cap could be pulling down your 5v...

    Apple IIe Resistor

    That's just a dcap (not a resistor) . That wouldn't prevent it from booting. Most issues I've found with 2e's have been ram related (4164's)

    LCIII Recap - Apple design fault -47uF reversed!

    I can confirm you have to change the polarity of c22. It's -5 rail and for some reason the mask has you putting it on backwards. They must have installed the cap reverse of what the mask says or used a bipolar cap at the factory. It would have never worked otherwise. Saying that... it's...

    IIGS high speed scsi

    Congrats! It's a must have for the IIGS! That and a Bluescsi (or your favorite - zigzagjoe's tinyscsi is amazing too!) makes loading things a breeze.

    SE/30 subject to analog board recap but decided not to...

    You can confirm that by just tugging (lightly) on the anode wire (with the machine off, obviously). You will feel the resistence from the cap if it's secure in the tube.

    SE/30 subject to analog board recap but decided not to...

    Yeah. It sounds like you didn't plug the yoke back in correctly, or you might have fractured solder joints the connector. It's a 4 pin connector on the top left of the board (closest to the monitor). You'll find it under right under the capacitors an inductors right there.

    SE/30 Focus Control?

    I would make sure you haven't bent any pins on your tube / check you neck board. Also check for cracked joints on the connectors header pins.

    My GS died today

    Input to the adb will be high. The adb will then trigger reset low for everything else.

    My GS died today

    Looks like it's at the ADB chip. The RC circuit at tp74 does the initial reset on powerup (thanks robespierre). The ADB also handles the ctrl-reset. Also... if you haven't done it yet I'd recommend capping your motherboard. One of my rom 3's definetly needed it.

    Hello, new here - two SE/30s, big mess, no video

    I know this is obvious, but check your brightness too. If the pot on the front doesn't show your screen getting brighter you need to adjust the pot on the analog board until you see some raster on the screen. That way you can see if the computer is doing something. Bad caps will prevent you...

    vertical line se

    W6 is just a jumper. I belive you talking about the width coil. As long as the ferrite core isn't broken it should be okay. Make sure if your adjusting it you only use a plastic adjustment tool. If you use a metal Alan wrench it will mess with the inductance of the coil and will make the Alan...

    Sorry... that's meant to say your your yoke connector doesn't have any fractured joints.

    vertical line se

    You don't have vertical deflection. Remeber... the tube is essentially on it's left side so the line you see from top to bottom is actually horizontal deflection. I would check the pads aren't fractured from the traces you'd been. That and make sure yournypke connector doesn't have any...

    vertical line se

    Verify your yoke us good. Check the resistance of the vertical and horizontal yoke of your old monitor and compare it to your new monitor. You want to make sure they're close to the same to verify there isn't a problem with your new yoke (broken wire, short, etc). If they're good odds are good...
