Anyone know when LG warranties a plasma panel, what parts/boards if any, come with it? Thanks!

Cledus Snow: Can I ask you a question?
Bo Darville: Sure, ask me what?
Cleedus: What the Hell do we want to go to Texas for and haul beer back here? What is that?

Re: LG plasma panel warranty
Panel is supplied (typically) with Y-sustain, Y-buffer, Z-sustain, control, and address buffers. Whether or not they are covered under warranty is a different matter, I would guess NO.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. -
Re: LG plasma panel warranty
A warranty Claim for a faulty Panel if upheld, will supply ONLY the Faulty Item, In this case, The Panel itself with nothing else at all.
--You'll be lucky to get even the top and bottom mounting-brackets let alone anything else on a Warranty job!
What Tom is referring to is when LG or anyone else supplies a Plasma Panel to another manufacturer to build a set with....
Like, LG supplied Sony at one time, and Fujitsu/Hitachi supplied Philips and Sony, but they supplied the complete 'Plasma Engine' for want of a better description, complete with SUS boards, Buffers, Controller and PSU, but no main-board. Often the PSU was sourced from a separate Co. such as Mitzumi, in which case, only the SUS boards, Buffers and Control board were fitted....Last edited by Alastair E; 10-19-2014, 12:42 PM.TELEFIX

I recently found myself the proud owner of a later-model Samsung plasma (the PN59D7000 for those keeping score at home) whose panel was, unfortunately, damaged in transport. I'm now preparing to part it out, but am curious as to whether or not any damage would have come to any of the components by attempting to power it up with the panel being broken. I read in one Avsforum thread (for whatever that's worth 😂) that the "scan driver boards" (by which I assume he means buffer boards) could be impacted by doing so. Is that actually the case? If so, since I don't intend on selling bad... -
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... -
TV flashes backlight then reboots over and over. no image. Client said it used to have image for a bit before rebooting. Got worse over time.
tcon is built into mainboard.
Only one cable goes to panel boards.
there is a cable from one panel board to the other that links them.
cost cutting measure that results in us having harder time to diagnose.
removing the link to the second panel board allows TV to stay on with stable backlight but no image.
used cut off tape method to mask 1 maybe 2 pins on the side of the cable that goes to that second panel board.... -
I had a the above tv qn55q60r that had a bad panel but everything else good. I had another panel here from un55nu6900 with bad leds and melted diffusers.
I put the nu6900 panel in and powered it up and it does work but there are lines vertical lines.
I was trying to change the panel type in the service menu but don’t see my exact panel. Anyway to fix this or someone have similar experience.
the clear picture is the panel type from the service menus on the nu6900. The other 1 is the panel type that was set for the q60r with the bad panel....01-13-2024, 01:57 PM -
I have a TCL 55P6US with sound and backlight but no picture. This model does not have a T-CON board, and the right (rear perspective) panel board is fed from the left panel board. I have not been able to induce any change by disconnecting the secondary panel board or the tape cut-off method on the primary board.
There are a bunch of voltages missing on the panel boards. I can't find any shorted caps of the panel boards, and all of the missing voltage rails read in the kiloohms, which leads me to suspect the issue may lie on the circuit board, rather than a short in the panel.
