If this player, which is identical to my LDX LD-696, is working, you better don't touch it if you don't have corresponding firmware.
This player which is of 2.2" screen have been used by lots of manufacturers to mount lots of different configurations, which my vary small details enough to bring you a wonderful Blank screens as it in my player (faithful dog).
I have had it with blank screen for months trying every possible firmware to make it return to light... not succeeding yet.
Your firmware version is rather old
00.00.0004
Date: 2006-11-14
I've seen new version of it dated 2007-06, which make more difficult to find proper firmware.
Just an example somebody here saves the same player with Walker firmware, downloadable here, I just can't with the same firmware.
Anyway if you still want to try and take the risk of spoil your device... in this site is the latest version of Firmware Update for rockchip and a couple of firmware that fits your device.
I do have a original firmware for this player too. I can upload it..
Let us know what you decide to do... we always want to know of people who take risks.
