      1) What replacement caps did you use?

      2) See "A guide on how to troubleshoot 2 seconds to black"

      https://www.badcaps.net/forum/showthread.php?t=10419

      look at transformer section, but read through everything to doublecheck.

      3) Post clear focused pictures AFTER reading

      https://www.badcaps.net/forum/showthread.php?t=1868

      Take your boards to a window on a sunny day and use macro mode. Take a top down view of all your boards (front and back).

          Hi thanks for reply
          The caps have no name that i can see
          220-16PHT 220uF 16V 105'c have NA and
          100-16PHT 100uF 16V 105'c have a large H
          Bought from little diode

          Look again and they dont say low esr but assume they were
          The inverter board is a seperate from the main board and is new
          Will upload picture of board later as its dark here (UK)

          Took this on cam phone not very good but gives some idea of board

          Paul

              Is your external PSU putting out the correct and stable voltage?

                      Sometimes it just takes a pair of fresh eyes!

                      I remember one university assignment where my friend spent 4 hours debugging his assembler code. He asked for my help and in 2 minutes I found the problem. It was something pretty simple, but he was so buried in details he forgot to check the simple things.

                              hey Im very new to repairing electronics with capacitors as well as using a multimeter so I need so help/guidance fixing this issue

                              recently I was handed a family members old NAD C320BEE that they had in their loft for storage for a few years but when powered on it went into power safety mode due to a problem on the protection circuit somewhere before it went into storage I was told it worked fine I found lots of people online talking about how the capasitors are known to be pretty bad in this model and can cause this issue the only problem being I don't have much experience sorting...

                              Hi all, I've spent the past week digging through the forums and guides to try correct my foolish mistake of changing hidden settings while tinkering around, and to be honest my heads overloaded so I'm hoping you'll be able to help.

                              I used a tool called 'Smokeless-UMAF' to access usually hidden settings in the bios. I tweaked one or two 'safe' things but made the mistake of tweaking a lot of settings under 'USB/Thunderbolt Configurations' when I didn't know what they did. For...

                              Xerox Versalink C505 bad printing in color mdoe
                              by pc_okay
                              Hello friends,

                              I have a problem with this printer Xerox Versalink C505 , printing perfectly in B&W but bad in color.

                              There is a little yellow ghost printing around color print.
                              So little text in color is unreadable.

                              I already change drum cyan & yellow with no success.
                              I try (i think) all avalable calibration in printer menu..
                              (black drum is dead but it's not the problem i think)

                              I'm not a printer specialist,if anyone has an idea?

                              Thanks !...

                              Samsung LS19A100, slowed down, colors changed, lines not very crisp
                              by panoss
                              In the above mentioned monitor, I removed the plug a few times and this resulted no power.
                              I opened it, soldered the dc jack and worked again.
                              But since then colors have changed, too bright (or something like this) and lines, eg letter, are not very crisp as they used to be, they are vague, like faded out.
                              I checked voltages on the main board, they look ok (according to the service manual. It' attached at the bottom):
                              IC600 (D9329)
                              pin 1 (BST) 9.6V
                              pin 2 (VIN) 13.5V
                              pin 3 (SW(Switching output)) 4.8V
                              pin 7 (EN)
                              pin 8 (SS) 2.6V
