    Philips 37PFL9632D/10, appears dead but has power

    Looking for a bit more advice please.
    An ex-neighbour from about 10 years ago rang me up out of the blue, asking 'Do you know who this is?' Long story short, his old Philips TV had 'died' while his wife was watching it. It's one of those ones with the LED's that shine on the wall behind the set, ambipure or whatever- doesn't matter anyway.
    Up on the bench, back off & indeed, there appeared initially to be no signs of life, except for a faint click when applying or disconnecting the mains. Turns out the click was coming from the speakers which also whined very faintly when power was applied. I couldn't see any obvious capacitor problems, so went about checking some voltages. There was zilch at the cathode of diode 6B05 (an S6 7BA I think) and further checks revealed that it was indeed s/c. So too was the PHD38N02 FET next to it (7B06 on the board) which fell apart as I removed it.
    Getting components here is a right royal PITA, so before ordering a replacement "N-channel TrenchMOS logic level FET" (to give it its full Sunday name) I just wanted to check if there is likely to be anything else, or even a cause besides simple component failure.

      MAC Display A1316/A1407 appears to be dead even after replacing the PSU three times ?
      by Michale32086
      I have an older 27" MAC Display that I simply loved.. Sharp clear display.. Then it crapped out on me..

      Long story short, I assumed it was the power board and replaced the PSU three times.. STILL completely dead..

      So, I was wondering.. Would a bad VIDEO BOARD cause the same doornail dead symptom???

      The thing is, this MAC monitor doesn't have any indicator that power is on.. In the past, I have only known it's "ON" when there was a pic on the display...

      I haven't checked voltages, as I am not sure where on this PSU to check.....

      Philips 50PUS6503 - dead panel? Picture
      by Rubenlily
      Hey,

      I gave up on my last TV and got a new one to try.

      Only vertical lines. Sound is OK. Screen is black with a few white lines until I change channel, then these colors gradually starts filling up the screen.

      Is this fixable in any way or should I just give up on this one too?...

      How can I be sure that my EC chip is dead?
      by double_DD
      Hi all,

      As the title suggests, how can I be sure that my EC chip is really dead?

      I've recently gotten into this hobby of laptop repairs, and have successfully brought back to life a couple with some easy fixes, mostly shorted caps.

      Now I'm working on HP Probook 455 G8, that had some "devil" run around on 3V line, burning a bunch of stuff. Luckily I have a dead 455G7 (for spare parts) so I managed to fix it (swapped burned parts) to a point that it will charge (both on barrel jack and usb-c), but it doesn't want to turn on. There is a 3V3 on a keyboard...

      Philips 50PUS6262/12 (chassis TMP17.7E LA) no picture
      by HP32Sii
      This is my first post on this forum, and my first attempted repair of a modern flat-screen LCD-TV (though I have repaired a few LCD-monitors, all with Elco-problems (high ESR). I have repaired my fair share of TV-sets and VCRs in the past ('90s) and was fairly familiar with the different Philips chassis (KT-3M, K12, K2, K3, K7 are some that come to mind). So I have a fair bit of experience on old sets. Obviously, modern TV sets are quite a different cup of tea.... no HOT or flyback-transformer inside, for starters....



      The set came into my possession by accident,...
