    42LG3000 2 seconds to black

    Hey

    i've got a 42LG3000 with the typical 2 seconds to black issue. Picture is still visible with a flashlight. I already tried to replace the inverter boards, but the issue remained the same. I then suspected the CCFL and opened it backlight up. The CCFL seem fine, but i found 2 broken ceramic cap and various others that seem quite dark and at the brink of breaking.

    My Problem is now, that those caps are 15pF/6KV and i have trouble finding some for a reasonable price. I found 2 sources, but they want 3-6€ for each cap. i would need 20-26 to replace all caps that are changed in color to be safe, which would way to much to fix such a old tv.

    I did find this one 22pF/6,3KV for 0,393€

    My main question is now, if i can use this one instead of the 15pF/6KV. As far as i've understood, a higher Voltage should be no problem. Is a higher capacity ok as well for the ccfl caps?

    Greetings

    The general rule I've always followed is that a replacement cap should be no more than 20% higher in capacitance than the original. So, I wouldn't go higher than 18pF.

      Samsung ccfl tv powerboard clicks every 5 seconds.
      by nomoresonys
      Having a problem diagnosing this old tv, seems to be a powerboard problem, trying to trace the problem from power in at ac cord to power out to ccfl lamps but not doing very well in the attempt, power board there: https://www.shopjimmy.com/samsung-bn...w-605563813499

      HANNSG Hi221 -- 2 secs to black feat. CCFL flicker & "burn" marks on power board
      by ttmi100x
      Greetings everyone,


      I have a HANNSG Hi221 monitor that exhibits two seconds to black issues (backlight goes off, display is still on as confirmed by shining a flashlight on it) with some additional oddities...


      The monitor failed on me with a standard "2 seconds to black" some time ago prompting me to initially replace most of the electrolytic capacitors (some of them were bulging/leaking).
      Things kinda sorta worked for a night, then the problem returned along with some flickering and "buzzing" noises.

      Upon closer inspection...

      Lenovo Legion 5 high fan spin turns off after 34 seconds
      by twonk9098
      Hi all,

      I have a Lenovo Legion 5 with a Ryzen 7 series CPU and RTX 3070 GPU. My issue is that it turns on and all seems fine except after a few seconds the fans spin up high and the laptop turns off after 34 seconds.
      I can get into bios and can even boot and login to Windows however after 34 seconds no matter if Im at the bios screen or booted into Windows it will just turn off.

      I have managed to run HWmonitor and the temperatures of the CPU and GPU are fine, I can also touch the heatsync which is warm but not hot.

      I have tried a few new bios but exactly...

      Help on Samsung Syncmaster T220 dead ccfl lamp
      by mikey5791
      Hi,

      This monitor previously is my main working monitor which i have been using for 8~9 years. Yesterday, when i switched on my pc from fresh to power on, the monitor is just black no display. I started dismantle to look inside the monitor power board but nothing looks suspicious or burnt. So i took my external ccfl inverter to try to power the monitor ccfl lamps which consisted of 2 lamps on upper part and 2 lamps on the lower part.

      Found out the upper ccfl lamp which is supposed to connect to cn304 on the power board did not light up. Then i installed a used working...

      Lenovo 15iml05 Power led lights for 12 seconds then off 12 seconds
      by liquidzorch
      Hello. I bought a faulty Lenovo ideapad 3, but it turns out the 3Valw buck converter burnt a hole through the board. I was able to clean it up, and remove all the shorts. I now can power the 3.3v rails from a bench power suppy while connecting the laptop to its psu, and I get the additional 5valw, 1.8v, and 1.05v, form what I can tell in the schematics, those are the only 4 voltages I should see before turning on, and they are present. When I hit the power button, the power indicator on the left side turns on (not the one on the power button), stays on for about 12 seconds, then turns off for...
