GE fanuc Series 21I-M led light problem!

[tvvism]

I have no idea about these machines. My dad has a GE fanuc Series 21i-M controller and the led that lights up the screen has gone out. i was wondering if it was easy to replace the lights because its hard for him to see.

Also certain types of compact flash cards he puts in gives him a memory card error 1010.

any help will be much appreciated or maybe a company i can call or a person i can talk to that can come in and fix this type of problem in the los angeles, california area.

If it's a color screen, they are quite easy. Early i controls are finicky on which cards you use. Was like that for about the first year or so. Later ones would read ata flash up to 100 mb or so.

it is color screen. is there a manual or something? or is it pretty self explanatory? for example just take out the screws get to the led lights and just switch em out for the same ones i can find somewhere?

the fanuc controller is about a year old im not sure when the problem occured but sometimes it would read the card and sometimes it wont. he only uses compact flash card. ive read around google that maybe its the computer you save the file to, they said it didnt read the ones that were saved from a desktop but some that were saved from a laptop worked on the fanuc controller

It's not actually LED's. Its a tiny compact florescent bulb, usually right along the bottom inside of the screen. Do not remove the control, simply unbolt it from the back, slide it out enough to get to the bulb, remove the screw and slide it out. Should have a pink and white wire harness to it. Bulbs are available from Fanuc ~ 80 bucks. You will need to get them the part number off the control unit, should be something like A16B-####### or A20B-######. Remember on a I series, the panel IS the control, if your not carefull you can erase all the memory.

I usually get CCFL lamps from DigiKey, <than $20.00.
It is often either the lamp or the DC to AC invertor, this is a small long thin board near the back of the display that the lamp is plugged in to.
If you are careful and have a sensitive meter, you can measure the output of the inverter, they put out up to 1000vac for starting, if there is output at the inverter and no back light, then it is 99% the lamp needs replacing.
