Just replaced my navigation LCD screen with one from Ebay for $130 shipped (seller was in Minnesota). I had a constant yellow hue and one spot of dead pixels.
My original screen was a 51U. I cannot tell a difference externally from the two LCDs. For some reason they cover up the "SHARP Made in Japan" stamping with stickers that say "Made in China".
No dead pixels on the new LCD, but my image was shifted off about 1 cm to the right. Bummer. Had to disassemble the whole thing and then reassemble with the LCD hanging by the ribbon cable so I could adjust the H-POS potentiometer on the back-side. I also noticed some ghosting, but adjusting the VCO potentiometer solved that issue.
Last photos shows before and after.
Comments:
- Don't forget to remove the protective film from the new LCD
- Place the LCD and electronics into the front plastic frame (has the buttons) first, then tuck in the 2-wire cable for the front light sensor, and lastly press the rear plastic frame on
- turn the H-POS counter-clockwise to shift the image to the left (about 45 degrees for me)
- turn the VCO in very slightly in either direction to remove ghosting and fine tune the image
Someone else who had the image shifted to the right:
