    Tips or tricks to identify cracked LCD panels on dead units?

    Tips or tricks to identify cracked LCD panels on dead units?

    Anyone have any tips on spotting cracked LCD panels on units that wont power up?

    I recently bought a lot of a couple dozen flat screens and discovered there were more cracked displays then I was originally able to see, which is ok, I am still money ahead.

    Now I have a handful of units sitting here that are dead due to power supply or mainboard issues. Starting to second guess myself weather to sink the money into them for replacement parts only to find out I have more cracked panels.

    About the only tip I know is to look at them very carefully at all sorts of different angles using various bright lighting.

    Just wondering if there were any other tricks I could use to spot them?

      1) get them in daylight ......... sunlight is better you will see patches where its broken sometimes a camera flash shows them up

      2) look to see what else theyre selling, boards and working tv's steer clear theyve had a go at it and knows the screen is damaged

      3) look for chips on the screen

      4) vertical lines on screen cant be seen until you get the unit working

      the above have saved me money

        Sell or Shim Solar panels?
        by eccerr0r
        Well, due to my grid tie inverter not accepting high voltages, and the fact that the lions in my solar panels are 36V (72-cell) I think I need to stick with 72-cell.

        However I have a few smaller panels that are 36, 32, and two 30-cell. The 36 and 32 together run at 75% efficiency (and subtract more with additional inefficiencies) when running in parallel with the 72-cell panels. The kicker is that the two 30s... generate 0% power when connected in parallel(!)

        So now what to do with these small panels?

        I could sell them...

        Or I could shim them....

        Soldering flex cable - tips & tricks
        by Prott
        Hello fellow badcappers,
        I have to solder a MacBook (A1708) screen flex - one of the two data flexes got slightly torn (2 broken traces). I've seen some videos on youtube where people scrub the coating and then simply apply flux and solder to the exposed copper traces (and then run a jumper wire). However no matter what I try the copper does not take the solder at all - the more flux I add the more it actually stays only on the iron itself.

        I am practicing on a spare flex cable and it's gettiing quite annoying - to a point I am actually thinking I have to be doing something...

        2004/05 AGP GPUs: Repair Tips and Tricks
        by SapientLion
        Hello, everyone!

        This is my first actual post on this forum. I don't know anyone here nor have any knowledge on proper etiquette that is supposed to be applied here... So, bear with me and my mistakes. I'll try my best. Regardless, here's my story.

        A few days ago, i discovered and managed to purchase two AGP x8 GPUs (ASUS Extreme N6600 [NVIDIA GeForce 6600] and ASUS AX1650PRO AGP [ATI Radeon X1650 Pro] ), from a trusted seller, for dirt cheap, which were released way back in 2004/05. They were primarily used for graphics design and 3D modelling. As far as know,...

        by corrize
        Hello, I have a solder iron pen (50w) with tips « 900m » (hollows ones, standard). I'm searching to replace mines because it's impossible to tin, they remain black and impossible to unsolder a mini SMD capacitor with. Bad ones.

        I'm looking to replace the iron tips but, on Amazon, Ebay… all no names, the sames. Sold by 10, 15 or more at low price and « pro » websites only one Hakko tips sold 20 dollars. I'm lost.
        Do you have brand of qually tips pls ?

        Same question for Kapton (for my other hot air iron), do you have brand or good place to buy, the true...
