    Philips 47PFL8404 intermittent inverter

    Dear all
    Philips LCD model 47PFL8404 had a blown high voltage cap across the inverter transformer output (33pF 6kV). Replaced and inverter operates.
    Unfortunately it won't operate continously. It stops after 1 minute to 1 hour.
    Is there a modification or service bulletin available to fix this?
    I have measured the other 2 HV caps and they are spot on value.
    Perhaps they have intermittent shorts?
    What does the expert panel say?

          Vizio E55-E1 bad backlights or bad inverter?
          by x_orange90_x
          I just got this tv today and it appeared to have no backlight on. After taking off the rear cover and checking again in the dark I can see that MAYBE one quadrant is lit.. But still it's quite dim. I was going to check the LEDs with my tester, and I found LED 1 and LED 2 + pins on the wire from the inverter, but I couldn't identify a ground. Nonetheless I tried using a mounting screw on the inverter board and also the chassis as ground but regardless my tester reads 300 which is what it reads when there is no voltage draw.

          I don't know how exactly to test the inverter itself. Is it...

          MacBook Pro 15" 2010 820-2850 intermittent charging
          by protocold
          I would like to get some help on a 820-2850 logic board with intermittent charging problem. Sometimes the battery will charge all the way and sometimes magsafe would be cycling between green and orange.

          I have already tried replacing dc-in board, swapping good battery, swapping genuine 85w chargers. None of that helps..

          when it is not intermittent:
          PPVBAT_G3H_CHGR_R is 12.07v

          when it is intermittent:
          When the light is green, PPVBAT_G3H_CHGR_R is 12.99v
          when the light is orange, PPVBAT_G3H_CHGR_R is 11.62v

          data line on the battery...

          Philips 8200 series 65PUS8204/12 stuck at Philips Logo
          by G33RT
          Philips 8200 series 65PUS8204/12 stuck at Philips Logo, it does not reboot it just stays on the logo.

          It does power up when pressing the power button.

          I already try the power button while plugin the plug with no result.
          Also put the latest firmware autorun-TPM191E_R.001.004.100.000.upg on a MBR/FAT32 USB stick at USB port2 with no result either.

          Could this be an PSU or eMMC issue ?

          APSINT3636VR 3600W APS INT Series 36V DC 230V AC Inverter/Charger schematic
          by Gentian
          I have a tripp-lite aspint 3636vr inverter charger which blow some of mosfet transistors. I replaced them repaired also the driver circuit and tested but the mosfets burn again.

          It work very well as inverter and also as charger if I let the rear switch in auto mode (inverter) and charger only(charging) but in auto when I connect the feed line 220V AC first time it pass ok to line and start charging the batteries but when I remove the feed line it pass to inverter mode and if I do it again the second time when passing from charging to inverter the Main transformer start making a...
