    Samsung t220hd buzzing sound after repair

    Today i fixed my old lcd monitor (2sec to black problem), replace 2 ccfl's that wer bad, the inverter and all the capxon caps with lets say Panasonic caps, i dont trust my local shops but this was all they had ! So now the monitor is working fine but whenever i try to change the color tone from dynamic to typical or movie mode the monitor is making a buzzing sound this also happen when i lower the backlight and some other things to the menu. The monitor is working fine only under dynamic mode :/ Im too tired to reopen it right now but the sound is definitely coming from the psu so probably something is broken there is ther a possibilty that the new caps are making this ? I dont have the old ones to try them :/ but i will try to purchase sometime soon quality brand caps. Can anyone give me an idea as what the culprit might be ?
    Thanks in advance

    Re: Samsung t220hd buzzing sound after repair

    I just disassemble the monitor, and found out that the noise is coming from the 2 ccfls i changed but now with the case open the noise is decreased to a minimum. Any ideas ? should i change the wiring (do i need a special type of wire or a wire with similar thickness will do? Or this indicates an even greater problem ?

      HannStar Hanns-G HC194d LCD monitor repair
      by momaka
      Normally, I never post repairs this quick after I do them, because… I am usually very slow. But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

      Samsung UN70NU6900F no picture and no sound
      by jchang
      Hi all

      I was just given a Samsung TV with the issue. I read various threads and videos and attempted the ribbon tape method to gain an image, but no luck.



      Symptom:
      No picture no sound.
      When I plug in the power cord, Backlight LED turns on for a half second and then turns off. The red LED next to the power button located center bottom flashes 2 or 3 times. When the power button is pressed after, it does the same thing.
      No sound at all.



      What I tried:
      1. I tried unplugging the left or right ribbon...

      Samsung UE60KU6079 backlight okay mainboard responsive, no picture, no sound
      by Ierwin
      Hello everyone,
      Ive got a UE60KU6079 on the workbench that is giving me some headaches trying to troubleshoot.
      The previous owner stated that there had been white dots on the screen which from the description sounded like some lenses fell of the backlight LEDs.
      He had opened the TV from the back, trying to get to the backlight, supposedly gave up, reassebled everything and gave the TV to me.
      I expected the worst like ripped COF cables or a cracked panel but could not find anything like that yet.
      Anyway I still fully expect that there has been something seriously damaged...

      by ChaosLegionnaire

      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...
