    What about a 7-watt ceramic?

    I noticed in the pics above that the resistors are on the far side, farthest away from the fan; maybe they get no airflow at all right there.

        Thank you for all the suggestions - in this case I've ordered both 120k and 150k 2w resistors as this was the closest I could find to the original items. I am assuming the ceramic ones will have a higher temperature threshold and therefore longer life?

            Yes, that is correct.

                That APFC circuit looks way too tiny. Might not be designed properly. I would say just get rid of the APFC circuit. The PSU uses an older half-bridge technology, so it should work fine without it.

                    Help with Dell Latitude E5470 that shuts down when moved at all. Powers up, but no charge, power jack has brown burn marks
                    by lowpost99@gmail.com
                    I have a Dell E5470 that powers up and boots windows no problem. Using a non-standard universal type charger, it shuts down immediately if moved, (power short in that charger or AC power jack) because the battery has no charge and isn't charging orange/white lights blinking on the front. When first powered up, BIOS power alarm stated that it could not detect the voltage setting and I had to dis-able the message to get past this. It got into Windows fine, as long as not moved, so I dis-assembled it looking for a cold solder joint on the power jack that I thought might be lifting off the MB, but...

                    HANNSG Hi221 -- 2 secs to black feat. CCFL flicker & "burn" marks on power board
                    by ttmi100x
                    Greetings everyone,


                    I have a HANNSG Hi221 monitor that exhibits two seconds to black issues (backlight goes off, display is still on as confirmed by shining a flashlight on it) with some additional oddities...


                    The monitor failed on me with a standard "2 seconds to black" some time ago prompting me to initially replace most of the electrolytic capacitors (some of them were bulging/leaking).
                    Things kinda sorta worked for a night, then the problem returned along with some flickering and "buzzing" noises.

                    Upon closer inspection...

                    Insignia NS-43D420NA20 backlight on no display - LCD panel burn failure
                    by howardc64
                    Eventually discovered a burn mark near lower corner of LCD. Here is a summary
                    • Backlight on, no image
                    • Disconnect right buffer board (view from front), left side display comes on
                    • Masked off pin 7+8 (both ~12,5v on both left and right buffer board) from t-con to right buffer board (view from front) display works but have some lines
                    • Buffer board is pretty simple
                    Removed the front bezel to examine edge of the glass. Found burn mark on lower right (view from front). Plastic bezel covering the burn mark region shows heat signature on the inside surface facing the LCD panel. Last 2 pics. Bright...

                    PowerMac G5 ACBel 614-0303 buzzing
                    by dcbw
                    The PSU works, but shortly after powering on (either in the G5, or by shorting the power-on pin to ground) it begins buzzing loudly. It also makes the LED lights connected to the same circuit flicker. It's definitely a buzzing, not a high pitched whine.

                    The buzzing seems to come from the high voltage side of the board, perhaps from the white relay. Could the relay be bad, or could the 5V supply be bad enough that it's unable to keep the relay on? Any pointers to help isolate the issue? Thanks!

                    AOC U27G3X strange burn-in
                    by Tom41
                    I have an AOC U27G3X 4K gaming monitor that I use both as a TV and for gaming on a Nintendo Switch 2 console. Recently, something very strange has been happening to it. After playing a game that has an on-screen timer for a few minutes, the last digit of the timer (the one rapidly flickering from 0 to 9) appears to burn in on the monitor. Going to a different source or power cycling the monitor does not help; there is a constant flickering area on the screen where that digit was.

                    It seems strange that only that digit would burn in, and NOT the other digits that are changing less frequently....
