      Replace the PWM in the power supply (common fault). Optocouplers also suffer.​

          HP x360 Chromebook 14A-CA, DA00GIMB6H0 REV:H, flooded, restored, slow and stuck in tablet mode
          by modtool
          Dear colleagues,
          I've entered the repair of the chromebook machines just one month ago and I've found some significant differences from the classic laptops or macbooks, so I'm searching some advices.

          The owner of this chromebook gave it to me after it has been left flooded by water for almost a week, so chances of repair were not so high, the mainboard was oxidyzed in many spots but I made a nice cleaning, resoldering and component replaging work and now it is almost working.

          Among other things I've cleaned many spots from oxyds, reballed CPU, EMMC, EC, replaced...

          Philips 40 PUK6809/12 Backlight turns off after 10-20 seconds
          by alpersen
          Hello
          Mother called and said TV turns off after switching on. So after turning on Philips logo shows and probably 10-20 seconds image disappears, sat receiver is connected and sound is heard from source. So I turned on my phones light and I can see the image it seems backlight was off after some time. I dis assembled the cover hoping to see a distinc cap blown or leakage. Here are photos I took (I was after 22:00 pm and maybe some of them are dark). Should I order and change caps on the power circuit or what would you recommend? Thanks...

          HP RP7 RP7800 from 2012/2013 worst fault - has "character"
          by Rayblaster
          Hello friends, I've got a nice toy to play with - it is an HP RP7800 All-in-one POS system. I got it for free and it has one problem - it turns on very rarely, and just for a few seconds. After that it dies and doesn't come on if I don't leave it unplugged for at least 2 hours. I've repaired motherboards before, this is not my first one, but problem with these types of faults is that everything you check on the board will usually be fine. This is the case for me here.

          I dissassembled it completely, and got my hands on the motherboard. Model No. is PIQ67H/Higgins 11047-I 48.3GD02.011....

          Philips 58PUS7805 Menu working but no/weird picture from video sources
          by Ierwin
          Hello everyone,

          I got a 58pus7805 that shows some weird behavior.
          The menu and remote work fine and the picture is looking crisp and flawless while navigating the menu.
          However, when a video source is displayed the screen either goes solid green (HDMI), solid black (SAT TV) or shows some fragments on mostly green background (AVI Playback from USB).

          I tried to reinstall the firmware through the menu which was rejected saying it already had the latest version.
          I managed to install the latest official firmware by holding the control button while plugging...
