      Definitely panel, any time you get a bar with one or more fixed lines it's pretty much guaranteed to be a bad plasma panel.
      Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
      For service manual, schematic, boardview (board view), datasheet, cad - use our search.

              Panasonic 55DX600u second fault - panel brightness pulsing on right side
              by fixxy88
              After getting the backlights up and running a second fault has emerged on this TV. I was going accept defeat and move on but thought I'd have a quick look at it in case it was something simple. The right side of the display exhibits a panel brightness (not backlight brightness) pulse every 2-3 seconds in a stable timing.

              I poked about on the TCON test points and found one voltage that is fluctuating in the same pattern. VGH-ODD (Pin 47 of U10) is sitting at ~-6.5v then goes up to ~28v when the brightness pulses then goes back down to ~-6.5v again in a repeating pattern.

              Panasonic SA-MAX770PU SMPSU board fault....
              by Rictech
              Hello everyone. 😀

              As per thread title, this unit has a serious SMPSU fault. It blows F1001, which is a 10A M205 in the phase from the mains input.
              Very first thing I tried, was simply replacing the fuse, but the replacement ceramic fuse blew immediately.

              Looking at the schematic for this PSU, I then removed what I thought was the next likely candidate: D1001 - the HV main bridge rectifier.
              This isolated the fault(no longer blows the main fuse), but does not point me to the actual fault.
              There are no devices that have exploded or otherwise show signs...

              Samsung QN75Q6FNA backlight no display, red LED blink 2x, fault in panel
              by howardc64
              • Prior owner tried a replacement main board. No difference.
              • Samsung 2x red blinking standby LED = panel fault
              • Jumpered FB_TRDY_1 (pin 1 CN1300 left. main tcon->left side buffer boards) and FB_TRDY_3 (pin 95 CN1301 right. main tcon->right side buffer boards) This allows testing individual T-Con (on main board) connection to panel on this Samsung. Found fault on left side (viewing from rear of TV)
              • Each side has 2 buffer boards, disconnected left side flex between 2 buffer boards. Fault is on the left most board.
              • Tape masking eventually isolated to CN1300 pin 15 (CKV4_GOA) Display

              what i went through dealing with my mobo with dead onboard sound!
              by ChaosLegionnaire
              so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!! what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol!

              i had to blow some dust off the board and heatsinks with the datavac as i didnt clean it up before putting it in storage. after finishing...

              LG 49UJ6500 LCD panel lighter band that goes away
              by howardc64
              49UJ6500 LCD panel has a lighter band on top when first powered on. Goes away (or gets much fainter) after TV on for a few min. After powered off for awhile and power back on, same band appears. If powered on immediately after powering off, no or much fainter band. Running the latest firmware.

              Disassembled the TV and lifted the LCD panel during testing. Band is on the LCD panel (can see the band on the panel as I lift it slightly) Backlight is perfectly even at the top edge. Double checked LCD panel alignment in the frame and is perfect but since band moved with the panel, its on...
