CCFL distributors in Oz?
Anyone - especially you other Aussies here - know of any Australian distributors of replacement CCFL's (preferably more affordable than the Farnell type of place)? I'm more than a little leery of the risks associated with international shipping of what are decidedly fragile items.

Re: CCFL distributors in Oz?
most of them get the CCFL's from overseas anyway so I think you'd be better off buying from the direct wholesaler overseas? they might be fragile, but I'm pretty sure they're packed very well to ensure they don't snap on the way...Don't find love, let love find you.

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.

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... -
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...10-07-2024, 04:26 AM -
I have peltir element glued to heatsink with something thick and sticky like putty... it cant be separate with force or heat without risk of breaking ceramic or damaged semiconductor layers due to force (eg if try twisted, pulled, lifted)... method that I am using is a single thread for needle (thin and firm thread of pure polyester that cant break with bare hands without glowes), and using it like a saw between heatsink and peltir. I holding a heatsink with knee against table. It slowly cut throug putty and release glued parts. It is slow proces, but preserve undamaged component and heatsink....

Hello all! Recently one of my two LG Flattron W2442PAs kicked out with the 2 seconds to black issue. After coming across a thread with a similar issue and performing some tests using my other fully functioning W2442PA, I had determined that the issue was with the CCFL bulbs (as the board from the bad monitor would drive the good monitor's backlights without tripping the CCFL protection, and vice versa the good monitor's board would trip the CCFL protection when hooked up to the bad monitor's CCFLs).
So to resolve this issue, I ordered a LED Backlight Strip Upgrade Kit from ebay,...05-25-2020, 12:47 AM
