How and where to locate LCD inverters
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 ! |

How and where to locate LCD inverters
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. wrote: Hello 1 I have 6 dead LCDs on my hand, all due to backlighting problems.

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. |
