    Philips 42PFL7432D/37 CCFL flicker with new Inverters Installed.

    Hey friends!

    I have been sitting on this tank for awhile and since I never have worked on a Philips I took it in.

    The panel was a victim of toasted IC's on the inverter boards (LG) I found a set of new compatible ones for the same price as the kit so I took a chance on them.

    They use the NEO magnet mounts as they do not fit the original mounting locations.

    When I powered on the Panel the backlights came on and the screen illuminated and when I hit the menu button the panel looked good but when light sensor (was turned on) brightened the screen the CCFL's or CCFL started to flicker/Strobe.

    It wasn't terrible but after turning off the Light Sensor it helped a little but there was still noticeable. After turning off all the other picture boot options like DNR/MPEG Color Boost and Perfect Pixel HD, no changes. It wasn't till I got to Dynamic Contrast is were I saw the flicker go away when I got to the DC option it was set to Maximum I turned it off and the flicker was no more. It would flicker in Medium and Minimum too.

    The basic level contrast on the panel was set to 100 with no flicker and DC OFF. When I start adjusting the basic contrast lower then 95 it starts to lightly flicker again.

    Is this a Bad CCFL or is there some sort of voltage problem with the new Inverter boards?

    I have photo of the insides but I left my Lighting cable at home for the iPhone...

    I don't even know if its worth dealing with as I have kinda hit a stone wall on reselling, I have 9 panels all up for sale and not one bite...

          Sounds to me--They aint the right ones, ie--Not as compatable as you were lead to believe....
          Especially as you say, the mounting points dont line up.

          What are NEO Magnet Mounts? --Are you using Neodynium Magnets to hold the boards in place or summit....??

                  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...

                  Design of CCFL Backlight Inverters with Frame & Bar Cores

                  Summary

                  Portable devices, such as notebook computers and personal digital assistants are developed rapidly nowadays, which places an increasing demand on display technology. The LCD with cold cathode fluorescent back lighting satisfies the requirements on display performance, size and efficiency.

                  The backlight inverter plays a crucial role in supplying the power to the lamps of these flat-panel displays.

                  The frame and bar ferrite cores, described in this brochure, are especially designed...

                  Samsung flicker - BN44-00932T board or else?
                  by fixit007
                  I picked up this TV that the prior owner said - just died.

                  Tested the fuse - burnt. A dead capacitor is visible too on the hot side (CP801). Got the replacement power board (cheaply - used). Replaced the board - the TV turned ON!

                  Now, about a month later (yesterday) I noticed the left side of the screen was flickering from time to time. That was already happening with the antenna input, not through HDMI.

                  Also, some glitchiness with a Fire stick on HDMI3 - I hit an app with quick dark screen in stick, the TV goes - no input. Then I had to choose the stick...

                  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...

                  Philips 8200 series 65PUS8204/12 stuck at Philips Logo
                  by G33RT
                  Philips 8200 series 65PUS8204/12 stuck at Philips Logo, it does not reboot it just stays on the logo.

                  It does power up when pressing the power button.

                  I already try the power button while plugin the plug with no result.
                  Also put the latest firmware autorun-TPM191E_R.001.004.100.000.upg on a MBR/FAT32 USB stick at USB port2 with no result either.

                  Could this be an PSU or eMMC issue ?
