Hi pcaddict,
No Iam frm Hyd. At the time of registration to this forum I was studying in Chennai. And yeah, I know abt Ritchie street, but no chance of going there now. Thanks for the information.
By the way, is your LCD a 16:9 format? Coz the resolution seems to different from the normal 7 or 8 inches lcd panels!
FFCs seems to be a rarity in only Hyd it seems!

and, i managed to strip it successfully 2day. But I have got only one fresnel lens. And now puzzled how to proceed??
Hey Maestro...
The ballast is what drives the metal halide lamp. Those what we call as chokes used in domestic flourescent tubes is also a type of ballast.
Well, even I am looking for Fresnel and Triplet lens.... I am originally from Mumbai, relocated to B'lore. I am going to mumbai in another couple of days, and have collected some info of companies that provide OHP spares. If you are also from Mumbai, we can chip in together and search for the lenses. 🙂

If you can give me your email addy or just sent me an email on macx001@yahoo.com, I can mail you the file.

Finding fresnel!
pcaddict,
let me share some jugaad with you all
Dont get stuck with the single fresnelor no fresnel problemFresnel is required to intensify or collect the lightand send it to the Lcd then stop it from scattering once again and send it to the projection lens,it actually increases the intensity a lot you will have to buy a double power bulb if you dont use a fresnel which means double heat weight powerconsumtion and other problems.
The final image depends on the quality of the main fresnel this is the one in front of the lcd (between lcd and lens) Use your good fresnel for this.use an ordinary fresnel available in stationary shops in A3 size for about Rs 100/-!!!! as the lens required to condense light, these are called Page magnifiers or map magnifiers only problem is they are not very think so you will need to make a simple plastic or wooden frame to support it tight.
And Remember the most important thing-All fresnel grooves have to point away from the lcd (plain side towards the LCD) otherwise you are doing more harm than good ie scattering the light, instead of collecting it.

Hi cromaclear-crt
I got the parabolic reflector from the local lights shop, all light fittings whether they are fluroscent or halogen or metal hallide come with mirror polished reflectors in metal, you can even buy spares, but you might have to make adjustments for your bulb size.
