fresnal selection
hi guys,
my pj work is in process.
not getting enough time to do it. i come by 11 at night from ofice and work on it.
i want to ask can we put the fresnal of 216mm fl in between lcd and lens instead of 343mm. would there be any difference in projection, as the work of fresnal is to collect all the light and direct it to a single point.

lcd problem
guys iam into some real trouble.
i stripped my lcd today.
the circuit at back of pcb wouldnt just come out, the screws were jammed, some how managed to bring it out.
while the front of lcd is matte black but the back of lcd has some shiny surface ,it shines like miror.
while looking from front i can see things behind but very faintly, but from back it is very shiny just like one way film used for car doors and sliding windows.
please advise what to do.

Can you plz tell me the panel spec.
I belive you purchased LCD Panel + controller board. If you are not able to get/find the spec, atleast tell me from where or from which model you got.
Is that an Antiglare layer, check the panel spec document
Also look at the Antiglare removal guide thread in diyaudio to identify that layer
super tv
it is super LCD TV.
i am afraid . i think my LCD is dead.
the back connector screws wouldn't just come out, which connects the ff c cable. i used some force ,after that i powered up the lcd to check.
but there was no display on lcd ,
all money gone to waste. now i will have to wait till i gather enough money for another tv.
can we get just the lcd. ihave the tv controller. the lcd is hitachi.

Hi guys i've decided to build a projector using an XGA lcd and this will be my first build. spent most of last week reading all the lumenlab posts and this one. i contacted lensel, pune today. they sent me a catalog for the fresnel lens but seems like they stopped producing triplet lens. does anyone know a different source for the triplets in india?
i also searched for the lcd panel and found the super 9.8" lcd tv somewhere in burma bazaar (Bangalore) he said it'll cost 4.5k. I'm bit hesitant to go with the chinese lcd when we can get a branded 15" monitor for the same price. the only disadvantage is the need to go for a bigger fresnel which looking at the lensel quote is only about Rs 200-300 more. i think its a fair choice to go with the 15" monitor. what do you guys think?
