I was at the flea market, and I found this neat Portable LCD TV
It’s a Lenco TFT-700. It wasn’t working, my best bet is that the power supply died (no power led, no backlighting).
So, you guessed right, I took it appart to see if I could use the screen. As suprising as it seems, I found datasheets for the various elements.
You’ll find the datasheets here :
The LCD is a Prime View model PW070XU4. It’s connected to a driver board via the 26 pins cable described on the datasheet. This board have a PVI1004D LCD controller chip and is connected to the motherboard via a 20 pins cable. I still have to find the pinout for this 20 pins cable.
On the motherboard, near the cable, is a SHARP IR3Y26 Video processing IC. I only have the datasheet for the IR3Y29 but they should be relatively close. The main IC on this device is a Renesas M61260 TV signal processor.
I just want to drive the LCD (via arduino or with analog signals), so I think that the Renesas and Sharp chips won’t be much of use to me.
I’ll continue to post here as soon as I discover more things. Cheers.
