    buying boards for TVs

    greetings. I am in the process of sourcing a board for my LG 50" plasma, and I have a question regarding part numbers. This board, the main, has 3 numbers - two labels and one masked. When I do the search I find that sometimes one may be correct but not another. For example, the EBR number may match, but not the EBT or EAX numbers (or some other combination - which leads to a large number of possible variations).
    The question, then, is which numbers matter, and which don't? Do I need to match all three? Are certain numbers critical and others simply workable/swappable variants? Is there even a generalizable answer to this question, or do I need to check every variant individually?
    This particular board seems hard to find, so I hope I don't have to match all three.
    A related question: is there a list of sources for boards/parts that has been found by people's experience to be reputable/reliable? The only places that I have found this board are sources with a pretty crappy web sites, with little or no info on where the parts came from, whether tested, returns, etc.. Makes me pretty nervous. Fortunately, I'm not in a big hurry for the part.
    Any thoughts or help is greatly appreciated.

        There is a sticker on that board and on that sticker it will say for example " EBT61875108 " , thats the board that you need.

        Why it says EBR/EBT/EAX i dont know but if you want to go for save then you must go for the number thats on your sticker.

          Re: buying boards for TVs

          Also , the differences are probably the screen size and a extra USB port. For example 1 board only works in 42" inch tv's or 50" tv's. ( Probably all work but need changing in the service menu ).

          Did you try Ebay?

          http://www.ebay.com/itm/EBT61855005-...item3a99b9592d

          You could visually compare your board with the one on this link. IF you search then use EAX64280507

            Thanks. I'll check out the match visually when I get home tonight.

            On my board there are two stickers (EBR and EBT numbers) and one masked number(EAX). That's why there are 3 numbers. Sellers seem to use any one or two of the three in their postings - I've seen all of them, but not all three matching my numbers on one board. Also, the fact that I have two stickers makes the 'sticker' rule ambiguous. That's why I'm confused.

            I just noticed that shopjimmy has a part number identification video on their parts pages. This is pretty helpful. I think they're saying about the same thing as you, plus some other good info.

              Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
              Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

              Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
              by Tynan Dill
              I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

              Upon bringing it home and plugging it up, it showed a standby light.

              I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

              The screen seems to blackout and stay black, but with a flashlight I can see the display.

              With my Playstation 4 connected via HDMI, and running a game I can hear sound.

              TCL 55S425 few horizontal lines, potential failure on both side of panel/buffer board
              by howardc64
              All left and right refers to looking from rear of TV (or looking from front with TV upside down)
              • TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
              • Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

              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....

              Insignia NS-LCD019-09 issue: Power light turns blue for 3 seconds, the flashes red before going solid read again
              by cajoeg
              Hello, I'm new to the group and to trying to repair a LCD TV. During the past few years, I've been collecting/repairing/restoring vintage personal computers (Commodore, Apple II, Atari, TRS-80, Texas Instruments, and Timex Sinclair). This has been my retirement hobby. Now I've gotten interested in trying to repair a LCD TV that I have and used regularly when working on vintage computers.

              The LCD I'm working on is a Insignia NS-LCD019. I've downloaded the service manual that I could find, but it must be a different revision since not too many items in the service manual match the TV...
