This problem is not depending on a kind of LED or bulb. The reason is that the display is a VFD (Vacuum Fluorescent Display) with no additional illumination.
The most common problem with VFD is, that the heater of the VFD is going bad. You can't change it because it is built-in. For experienced repairman it is possible to higher the heater voltage or the anode supply to gain the brightness a bit. But thats a tricky thing.
Sometimes it may help to clean the display cover from inside. This is what you can do first. The reason for getting dark by dust inside the cover is that the VFD is working with a anode voltage wich is a bit higher (about 30V - 50V). This sucks the very fine dust electrostatically into the casing.
To clean up the protective display cover from inside, remove the casing and also the cover in front of the VFD and clean the dsplay protection cover (the VFD istself is usually clean). Maybe that's it - but maybe not (that means the VFD is going bad).
Hope it helps.

The light of LCD (liquid crystal display) is not working


Most likely your inverter board has gone bad. Really the only fundamental difference between LCD and LED TVs is the back light technology. They both use sheets of LCD crystal cells that open or close what are called shutters, to allow colored or non-colored light to pass through, the only difference is that LED TVs use light emmiting diodes(LED) to create the back light that causes the TV to display the picture and LCD TVs use compact fluorescent bulbs (well tube bulbs usually) to create that back light. CCFLs need a high voltage to vaoprize the mercury in the bulbs to start working and since the AC in your TV transformed into dc when it enters the TV that dc needs to be transformed back into AC because those bulbs need a high frequency to operate. This is accomplished by an inverter board. Most likely if you cannot see the picture of your TV then your inverter board has failed. You can easily check this by turning your TV on to something with a picture(broadcast TV, a DVD player, your computer playing a video, a video game console, etc...) and placing a flashlight up against the screen itself. You should be able to see part of the picture. If that's the case you most likely need a new inverter board. eBay is typically the cheapest place to get that board, but unfortunately, sometimes Electronics are poorly engineered or manufactured, causing the vast majority of a certian model or several models (if the manufacturer has a habit of using that same board in a bunch if different models they produce) to fail, and so aourcing the boards you need to repair your set may be difficult to downright impossible. The only thing you can do is to figure out what that board's part number is and search it online starting eBay and then moving to google. It maybe easy as doing one simple search on ebay, it may take hours of research on the web, or all the available spare may hve already been snatched up by other consumers who also had their sets fail. If that's the case, there might be somewhere that is selling board refurbishing services. You send them your board, they test and replacing a failing components and they ship it back to you.

Good luck and please give me an up vote if yoj found any of this helpful.

How do i change a bulb on a zephyr verona range hood


I could not turn the bulb, and the rubber glove approach did not work. I unscrewed and removed the middle cover, which meant I could easily reach inside and turn the whole light bulb fixture.

Display is faint and to light to read


Turn the calculator on. Hold down the "C" key (just above the ON key) and press + to darken the screen. If you go too far, use the C and - keys to lighten the screen.

The LED display on my console is starting to become unreadable from lights burning out can I fix or do I replace? If so where?


You cannot replace bulbs in the led display you will either have to buy a new one from BMW or get one from a scrap yard. This is a common problem with all the BMW's with the led displays.

The display light doesn't come on to indicate what the unit is doing (frequency, mode, etc.)


I assume that it plays, you just can't see the display. It may just need a new display bulb, that back lights the display.

Display is so light that I can barely read it, I've replaced the batteries and no change


Have you attempted darkening the display on the calculator through the function keys? Push "2nd" and then push "up" a few times. After resetting the calculator, this setting will always revert to a lower, unreadable setting. I'm sure TI knows about this, but they probably arent too inclined to fix it.
