This dvd player is having a problem with the video input /output circuits. This could be a minor problem with a loose connector or some over expanded solder joints. It could also be a problem with the video ic have a problem with its circuits. The connector problem and the possible cold solder joint problem can be repaired. The dvd player must be taken apart and the connection cleaned and repaired. If the problem is with the video solid state components, you will have to have it repaired by a service center. The video has a main ribbion connector that connects the laser lens to the main board video inputs. This ribbion cable usually will run under the laser transport mechanism. It is connected to the main board and laser transport by clamping connectors. You can look and see if this connector is loose or bent and has lost its function. Try cleaning the contacts points of the connectors and the connectors on the main board and laser transport.Also look for bad or cold solder joints in the areas of the connectors. Try to resolder these points.Use new solder to insure a good connection. Remember to only work on these dvd player with all power disconnected. Always wear anti-static wrist bands and gloves when working on the dvd player to prevent further damage. If the cleaning and repairing the of the possible cold solder joints do not repair the problem, you probably have a bad video chip and should replace the dvd player.I hope this information helps you with your problem.

LG RC797T Region Unlocking Codes

Purchased two of these VCR/DVD recorders (for the ATSC-digital tuner) in March 2007 at Best Buy. They play PAL/region 0 out of the box. To enable region-free playback I used the CD-ROM previously made for my LG LST-3510A. Visit this link for the files to burn your disc:

http://aiwaownersnetwork.tripod.com/pages/lg/5000_series_firmware.html

Next:
--Power on the player and load the CD-ROM
--In a few moments a text box appears displaying current DVD region and a second line to change DVD region
--Press the number you wish (most likely "0") on the remote control
--Press "Enter" on the remote control
--In a few seconds the player will eject the disc. Remove the CD-ROM from the tray and power off

Upon powering on the player my region 2 and 4 DVD's play fine but Macrovision still remains.

OR

Click the HOME button on the remote with the unit in 480i resolution
Click the setup page
Click Start
Click TV Aspect
highlight the 16x9 wide aspect ratio
enter on remote control this coded sequence:
1397139

Edit specific "Options"

Option 2: 35 (enables Divx/Xvid playback)
Option 4: ff (enables Vcd and SVCD playback)
Option 5: ff (enables region free playback (region 0) DVD playback)
Option 6: ce (enables Insignia brand startup logo on boot)
Option 6: c0 (enables LG brand startup logo on boot)

Mintek

The part that reads the DVDs is defective. I would suggest to try cleaning it using a lens cleaner, hopefully that works.
If the cleaning does not work, it might just be cheaper to buy a new one instead of repairing this one.
