Usually the code on new tv's is 0000 (sometimes 3 zeros) or 1111. I did the same thing on my Hitachi 42in plasma and locked the parental control by accident. Give that a try and let us know if it works. If that fails, look up the customer service number online to your particular make of tv and ask them. Good luck.

Unlock keypads to a Soyo SYXRT4791AB 47 In. LCD TV


Not a solution but a suggestion, the 43 page user manual if you have it or can find it (I looked and saw only a reference to it being 43 pages) will almost certainly have the information on how to unlock the keyboard, find that and you should be able to unlock it.

Hi! Somehow got `Key Locked`on my 42LCD LG TV screen. Can not use remote anymore even to turn it off..Can not find manual to read what should I do in this situation. Could you help? Thanks!


From owner manual:


• If Lock is already set, enter the password as requested.
• The TV is set up with the initial password "0-0-0-0".

• If you ever forget your password,

key in '7', '7', '7', '7' on

the remote control. Then, the

password reset to '7', '7', '7',
'7'.

You should download the user manual: www.retrevo.com

We have a goodmans gtv14t5dvd without a remote control or instruction manual. my children have somehow managed to put the child lock on and now i cannot do anything with the tv as it just says child lock...


If you were to log on to the manufacturer's web site, I think you will be pleasantly surprised as usually one is able to download, by model number, Customer Instruction Manuals, list of Dealers for spare part supplies as required.

That may help

Just Google the manufacturer's name and follow the links. Make certain you are directed to the manufacturer's web site as some search engines direct you to other sites and they charge for the information that is normally free of charge.

I hope this helps.
