    Westinghouse TX-47F430S, weird colors and popping sound now nothing

    Got this 47" tv a while ago. It powered up and I saw the W logo on the screen so I bought it for 15 dollars at the recycler.

    Finally got around to looking at it today. Powered it up and hooked up a source to it. The colors were off. It was like looking at a 3 gun RPTV that has the alignment of the guns off so you end up with that weird wrong colors and so on. Even the colors in the menus weren't right.

    I then tore it apart and looked at the mainboard and the power board. Everything looks good. No leaking caps or anything. I didn't touch either of the boards on the left/right (Inverter? Driver boards?).

    Put it all together and powered it up. The W came up and it still looked odd. I then and moved the tv a little bit and heard the distinctive zzzz sound of a short circuit. Unplugged it and looked, could't find anything.

    Plugged it back in and saw a spark coming from the left side inverter/driverboard. Unplugged it and opened up the cover to the untouched driver board to see if i could see anything. I then noticed that the high voltage power cable going to the CFL bulb was barely inserted. That is where the spark appeared to come from. I plugged everything back together and powered the tv back on. No zzzzz sound and everything seemed to be okay except now I get no picture. What did I do?

    Find your Tcon as well and put up a good clear picture of that.

    Test all fuses and tell us which you have tested so we know.
    Please upload pictures using attachment function when ask for help on the repair

      (Weird) BIOS info for HP Pavilion Aero 13-be1021AU
      by Loki_Fido
      Hi folks,

      This HP Pavilion Aero 13-be1021AU came to me for a repair. And it seems to have a weird BIOS chip. (Pic attached)
      I asked my CH341A to read it and doesn't even know what to do with this. We are both very confused.

      BIOS - XMC 25RU128CH10 (1.8v)

      What the heck is this? I looked all over the MB. This is the only bios.
      When I asked the NeoProgrammer to detect it, it just pops up an empty screen, and asked me to enter the bios number. And when I did, it doesn't do anything. NeoProgrammer showed me just this SPI ID: 204418. Don't know what...

      Philips 70PUS7855/12 bad colors when applying the tape fix on teh T-con board
      by silikon77
      Hi!
      Got an 70 inch Philips tv model 70pus7855/12 from scraps and I decidet to give it a go. I'm an enthusiast but no porfessional in the electronics.
      Found some advices watching youtube nad came up with this:
      It came with no picture, after diagnosing it I found out that the right side of the T.con board was faulty.
      I taped down the clock signals and I got a picture but the left side of the panel has less pronounced colours. Only the right 3rd side of the panel has good colors.
      See attached picture.

      I tried a few combinations to block individual clock...

      APC BR1000G battery backup has a weird issue sometimes a bad battery icon and making a weird sound for about 30 seconds
      by sam_sam_sam
      This started a few days ago and does this about every 8 hours

      After it does this it goes back to normal no bad battery icon and no weird sounds and it goes to battery backup mode so I am not sure what is going on with this battery backup

      The battery backup is about 3 or 4 years old

      Dose anyone have any idea on how to troubleshoot this issue I have never had a battery backup do this kind-a thing before so I am not sure exactly how to troubleshoot it and where to start

      820-02020 Super Weird Issue: Keyboard Input Character Map "Wrong"?
      by ugamazing
      So, I have a really bizarre issue that I'm struggling to identify the cause of. Working on an 820-02020 board with some bizarre keyboard/input-source character mapping. My suspicion is a possible damaged SPI ROM (U1970), perhaps, but I'm really not sure in this case:

      1. The issue is pretty weird, but when installing MacOS, I noticed my WiFi password did not work. I quickly realized the special characters (!@#$%^& etc) were not mapping correctly.

      2. I noticed the keyboard layout/input-source is defaulting to JAPANESE every single time I restore the board. I am not...

      AOC 2216Sa monitor displaying weird colors.
      by PopcornMobo
      I found this monitor at the dump right when i was in the need of one.
      The monitor is not smashed and works fine.
      The lack of "LED" stickers on it tells me that it's got CFL in it.
      One thing about it is that it's displaying colors wrong.
      It's like there's these very rough transitions between various shades of colors, almost as if there's only about 32 colors.
      Also every second vertical line of pixels is darker where the image is also dark.
      The only example to describe this i can think of would be maybe a compressed image.
      Now that i think...
