    lg 60pb690v

    Hi

    I was wondering if I could get some advice regarding the top buffer from a lg 60pb690 plasma tv.

    With all boards in place, all the voltages are present apart from the 18v and the 187 v (which is fluctuating). But no picture.

    Once the top buffer is removed all voltages return and are stable inc the above 18v and the 187v. The bottom half of the picture is present.

    On the top buffer I removed a cap (c873 please see attached photo cap with red arrow) which I found to be reading short.

    I removed it but found that the short is on the cap pads.

    I have done the buffer test and cannot find a faulty chip on the buffer board.

    Any help would be appreciated thanks in advance

      Found the short - it was c865.
      Just wondering does anybody know its value?

      I was going to use a ceramic 4.7 100v cap?

              MacBook Pro 14" A2442 Short on PPBUS_AON but no short present when injecting voltage!
              by Stephen
              I check PPBUS_AON and there is a short present on the line, the computer shows a short when testing for short to ground, so when I inject voltage into the line, I get 0AMPS so no short is showing up. I have replaced a blown cap on this board that exploded and tested for the short and it is now removed. Any suggestions? I tested voltage at the line when the fuses are connected and I am getting 1.2 Volts at the line.

              Extreme High Current & Low Voltage Short Killer ??
              by DynaxSC
              Hi Folks

              I'm looking for a extreme high current short killer solution for a reasonable cost.

              I have an LGA1700 motherboard (ASUS PRIME Z790-P WiFi) where I exchanged the LGA socket already 3 times, and every time after the socket exchange I get a short of power supply lines VCORE (V variable) and VCCIN_AUX (1.8V).
              After taking off the socket, the shorts dissappear again.
              The soldermask on the socket is already partially demaged from the heat, so I have reconstructed the soldermask by manually painting the missing soldermask parts with a very small top of a...

              Problem

              This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

              Help me find the short circuit on this WORKING Nvidia GTX1650
              by aaronkatrini
              Hi all,

              Recently picked up this GTX1650 at a local flea market for a low price and wanted to use it on my secondary PC. I first tested the card and saw the fan spin for a split second and then nothing. Immediately I thought of a short circuit. Disassembled and found a shorted SMD capacitor, injected voltage into it (1V/4A) and two Mosfets got hot immediately (QN3103 & QN3107). Desoldered these Mosfets and the card turned back to life.

              Bought replacements from Aliexpress and replaced them afterwards. Tried the card but still the saw the fan spin for a split second...

              Lenovo IdeaPad 3 NM-C961.no display
              by lapfix
              Hello everyone.
              lap and motherboard : IdeaPad 3-15IGL05 Laptop - Type 81WQ
              NM-C961.
              Behaviour : connect charger it power on automatically ,reach 0.170 amp than down to 0.74 amp...no display.
              with battery connected it reach 980 amp than 870 ...no display
              No short ; no corrision no intervention before.
              Try 2 differents bios versions same behaviour.

              Some measuremets :
              PL 1600 = 5valw present
              pl 1100 = 3 vlalw present
              pl 100 = 0.221 v without battery and when battery connected 7.8 volt
              pl 6602 = 1.2 v
              pl 6603 = 1.056v...
