hey,
using the following parts, I am building a projector that uses a 15" lcd hdtv:
dukane 680 overhead projector
POLAROID FLM-153B 15" INCH LCD TV
and 4 80mm computer case fans ran off a 230 watt AT power supply for cooling
the lcd tv's native resolution is 1024x768, so technically 1080i on this thing will just be a compressed image since the resolution of the lcd isn't high enough to be a true 1080i. but this monitor does have a built-in tv tuner (just regular cable, no built-in hdtv tuner 🙁 )
this monitor also has component video, composite video, and svideo input ports. which will make this projector into one hell of a gaming/tv viewing/computer projector.
however, I currently have two issues with this setup:
- the projector blockes the corners of the image, this could make for parts of the image being cut off.
- the lcd has the classic ribbon cable that I have seen in other lcd monitors, basically there is a circuit board that sits to the side of the lcd that is attached directly to the lcd, i forget what it is called but it is obviously responsible for putting the image on the screen. i have seen monitors with only one board, but mine has two, and has a very short ribbon cable connecting them, so short that I can't move the boards away from the lcd itself, thus blocking part of the image itself. i notices however that the contacts for the ribbon cable on each board just happens to be the width of a individual cable on an 80 pin ide cable (80 pin are the newer ones designed for 1.33 gbps speed, not the older 40 pin design commonly used for cd/dvd drives)
however, I doubt conventional soldering would be wise for such small cables. has anyone ever tried using the lcd without the second board being connected via the ribbon cable?
