Recently one of my customers was disposing some dead HP LA2206x monitors that were out of warranty. When I say “dead”, it just means that they were not powering on. As an electronics geek from the 80’s I knew it was highly probable that this is just a simple power supply issue and well within my abilities to repair them. So I took them home and soon found that there is a common problem with the power supplies in these monitors where a diode is faulty.
The following photo shows the ILPI-263 VA 491A013G1400R power supply unit with the D854 and D855 diodes highlighted.
