How and where to locate LCD inverters

[penang]

Hello 1

I have 6 dead LCDs on my hand, all due to backlighting problems.

They are of different brands, from samsung to toshiba to whathaveyous.

They ranges from size 15 to 21 in.

Need to know where to get the inverters from them ? Is there a "one
size fits all" type of LCD inverter that I can use of all 6 of my dead
LCDs ?

Please help !

Thanks !

The one size fits all approach will get the displays working, but you'll
probably lose things like brightness control. If you can find one that
has an enable pin then at least the backlight should be able to shut off
when the display goes into power saving mode. Just google for CCFL
inverters or try ebay.

No, you need an exact replacement inverter, specific not so much to the
LCD panel as to the monitor or laptop into which the panel is being
installed. The only connection between the inverter and the panel is
two wires to each lamp (most smaller LCD panels have one lamp, most
larger ones have two lamps). The more involved connections are to the
controller for controlling lamp on and off and brightness.

Either get the inverter as a spare part from the device mfgr. (again,
the maker of the device that this goes into, not the maker of the LCD
panel that it's used with), or buy one used off E-Bay or from some other
source. Match up the part numbers, and/or be sure that the replacement
is physically identical.

Agreed. I've rarely worked on those but they are made on custom boards to
fit VERY exacting and confined spaces. Trying to bypass going direct to the
maker's supplies will cost more (in time, effort, plus cash) than paying
what they ask. So much so that this might be why they charge so much. They
know damn well they can get that money. And they might not cost that much
anyway, they can't fleece a repair person quite as closely and ruthlessly
as they can fleece a member of the public who doesn't know that a £90 PSU
is really worth £30 or less.

Look at the firm's product line though. To save money they might use the
same custom board in many machines. You might find a low-end version cheap,
and save money if you don't want a regular supply of bits. Still worth just
paying up front though, unless you've got the time and attention of a
repairer of laptops and such.
