    Replacing CCFL - Now only halfway lights up

    Hello all,

    I ordered a couple of CCFLs to replace two broken ones and have finally wired them up. The entire setup has 4 CCFLs in the circuit (two of the original four are fine). Now my problem is, the 2 new CCFLs are only lighting up about halfway...I'm not too sure why this is happening. Anyone have any suggestions?

    Thank you!

      Do the new pair light half way up on any pair of the lamp connectors?

          Perhaps they are designed for a higher voltage and don't have enough to light completely?

          Just my guess, I may be completely wrong!!

              maybe they are not connected right.like no return lead?
              plug that pair into the other channel and see if they work.i have gotten an occasional dud like 1 in several hundred but doubt you got 2 duds.

                  hp elitebook 840: lights up halfway
                  by byroberta
                  Hi, I have a problem with a hp elitebook 840: connecting the power supply, only the LED lights up. And from the button does not turn off. The CPU heats up. Screen is off.

                  -I replaced a cracked capacitor on 3.3v
                  -On the motherboard there are only 19v, 5v, 3.3v 1.05v
                  -I reprogrammed the two bio chips.

                  But nothing has changed.

                  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...

                  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.

                  Assuming...

                  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...

                  Christmas lights - Something I am doing wrong
                  by Francesc V.
                  Hi:

                  i am trying to repair this Christmas lights from my parents. They are incandescent lights, no led lights.

                  I have tried with 12V a 24V small lights that I found in Aliexpress but is obvious that are not the right ones. They last microseconds connected. Do they blow because of Amps or Volts?

                  If I measure the Amps in the string........it's only 90mA. If I measure the Volts in the "green box"......it's between 0 and 190V, but doing a little bit of maths from the number of bulbs in series.......it's only about 6V per lamp.

                  Could...
