How to re-set all the Option Codes found on the 'secret' Technicians Menu?

After entering the 1397139 number on the remote,I got to the'secret' Service Technician Menu. I did this to make the player Region Free,which was sucessful( I changed Option 5 to ff ). However, I had nervous fingers and accidentally changed some of the other Options as well. Now the player fails to accept any BLANK media such as DVD+r or +R/W. It says"unknown disc" and ejects it. It won't allow initialization either. But it does play finalized media. I think i basically just need to know what the original factory set Option Codes were so that I can reset them. Dave p.s. I tried to make credit card payment but it keeps being rejected because it says the expiration date of the card is not valid....they ARE valid !!!

Jvc tv tuning without remote

If your TV has no 'Menu' button on its front panel controls, it will be difficult to make an auto-tune to it. Anyway, try to enter its 'Menu' option, using the remote control you have. If can, you will win. Otherwise, buy an other universal remote control, which will help you to enter the TVs' Menu option. The one more thing you have to try is, to set an other code to your TV with this remote control. If it too do not help you, think of buying an other remote control.
If you wish to buy a genuine remote control, you have to contact the authorized service center. If you wish to buy a universal remote control, you should know about, which brand remote control have set-up codes to your TV brand, and buy that one according to availability. The first thing you have to do is, to confirm the number of digits in the setup codes to your TV brand. There are 4 digit, 5 digit, 3 digit and even 2 digit codes. You can make it sure by entering '0s' at the code enter window the TV dispays, and asks codes. Enter 'Zeros', and count how many zeros can be enterd. That number will be the number of digit of setup code, the TV/Device need. If you can enter 5 zeros, the number of digit in the set-up code to your TV is a '5' digit one, if only 2 zeros can be enterd, the number of digits in the set-up code to your TV should be a 2 digit one, and so on.. If you wish to get more details about this, try the sites linked here. & Both the sites have setup code list, and setup procedure to many popular brand remote controls. Check the site in 'Mosaic' view. It will make search easy.
It will be preferable to buy its genuine remote control by any way.

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:

--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.


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:

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)

Jensen VM9412 Video BYpass

You can try the procedure for the VM9311TS model (the one I have) - I don't know if it'll work but it's worth trying. Put in a DVD, and let it start playing. Then hit STOP on the remote twice, and enter the code 1264. If you were able to see the actual movie at this point, you'd see a menu pop up. Push down twice, then ENTER. At this point the blue screen should clear and you should see the movie itself. You'll have other options on that menu, like a macrovision option to allow you to see burned DVDs. Set what you like, then on the remote, hit SYS SETUP twice to lock in your choices.

While having one too many beers my friend managed to use the remote to get to the 'secret' Service Technician Menu for my LG RC797T DVD recorder to make it Region free. This he did mange to do, however his...

In 480p resolution, you highlight the 16.9 aspect ratio from the TV Aspect menu option in Setup and then type 1397139 on the remote. This brings up the service screen with all options and machine information.
Optimal (best) settings are as follows.
1 : f 2 2 : 35 (this is DivX)
3 : 93 (macrovision?) 4 : f f (Vcd/Svcd)
5 : f f (region free) 6 : c0 (c0 = LG logo)(ce = Insignia)
7 : 04 8 : 15
All I can say is Keep these and and dont mess around or you can kill it....
