This is a nice easy mod to install. It greatly increases the battery life. Highly recommend if you are not ready to go for the McWill screen replacement.
I remember reading somewhere that this kit was used to backlight a TI84+. I couldn't find where I saw it so I decided to poke around for some voltages on the ribbon connection and found what I needed. I had to modify the backlight a little bit to make them fit, but everything worked out as good as it could have - bright screen, powers on and off with the calc, relatively simple to install. If you want to check out what I did you can find it on my youtube where I tried to make a decent "how-to" video for it. https://youtu.be/3apdGCHpDwo
Excellent product and costumer service !
What you can expect:
x2-x3 battery life in the Sega Game Gear
Reduced temperatures aid in longevity of other components
Traditional install may be intimidating to beginners
Traditional install will be a pain for all skill levels
My first install was preformed using the instructional video provided for this backlight which requires cutting the LCD away and butchering the diffuser. If you haven't installed one of these yet traditional methods aren't fun and requires an exacto knife, dremel, a lot of patience and plenty of potential for an OH S*** moment leaving screen modding your only option if that happens. Your mod could instantly jump from $10 to $100+
So I made it easier and now the only challenge is the 4 florescent tube components to remove. No cutting of any kind and your diffuser remains 100% intact leaving it free to do its intended job; diffuse your backlight.
Backlight no longer takes the place of the diffuser resulting in a more authentic look.
Screen alignment is no longer a "fiddly" process. Provided spacers allow use of reflector shield screws without further need for the reflector shield itself.
Regardless of which route you intend to go, traditional or with the mounting kit, the screw posts on the diffuser are very brittle. Colin points this out in his installation video during the cutting process. The screw posts are no different and, in my experience, they can fall apart simply by removing the screws. If this happens do your best to put the pieces back in place using super/krazy glue. If glue fills the entire hole take a toothpick and gentle thread it through the hole to prevent it from becoming filled with hardened glue. I would also advise applying glue to the exterior of any non broken screw posts. This will help reinforce them down the line hopefully preventing them from cracking altogether. Allow the glue to fully dry before proceeding.
