Remote with TV stopped working for vol, AV, and mute. Only power button works. Used new Batt; no change. Used buttons on TV; none work there too. Is there something broken on TV?

Power problem are cause by many reasons, i.e Power supply circuit, Lamp driver circuit and most often the TV detects an error cause by power surges. To protect TV from further damage most LCD TV have protection circuit built internally. If this is the reason of your LCD TV not powering On, an error data must be reset back to zero.
To change data you will need to access the service mode and change the value of lamp error code to zero (0). Entering service mode requires a trained TV technician. Changing data can cause more problem to your television. If you are not qualified to service your television, please do not go to service menu codes. Moreover below are the process, pls do so at your own risk.
* Unplug the TV * Press and hold the {VOL -} + {CH+} buttons located on LCD TV unit (not in remote control) Note: If above didn't work, alternately use (VOL -) + (TV/AV input) buttons located on LCD TV unit (not in remote control) * While holding the above buttons, plug in the TV. * The TV will turn on with the "K" or "K123" appears om screen. * Use {CH+} {CH -} buttons to go and display the service menu. Note: If above didn't work, alternately use (VOL -) + (CH -) buttons. * Search for "LAMP ERROR menu" from the displayed service menu by using "up or Down cursor" from remote control, or alternatively use "CH - or CH+ to select "LAMP ERROR" * change it to zero (0) value, using {VOL+} or (VOL -) on remote control. * Turn the set off to exit the Service Menu.

Hello

If you are looking for its service menu, there is no code, but some doings is necessary as follows.
Two proceedings are given. One amoung them will surely open your TV to service mode adjustments.

To enter the service menu do the following. Most of the sanyo sets will get positve results with this.

Unplug the power cable.
* Press and hold the {MUTE} button on the remote control while plugging the power cable back into the outlet.
* Keep pressing the {MUTE} button until the TV powers on with the Service Menu displayed.
* Use the {CH+} {CH-} buttons to select menus.
* Use the {VOL+} {VOL -} buttons to change settings.
* Some menus might have sub-addresses. Use the numeric buttons {0} to {7} to adjust sub-item data.
* Press the {MENU} button or turn the TV off to exit.

i have a goodmans tv GTV69RFDT and i have brought a one for all remote urc-3920-urc 3940. All the codes dont work, i have tried the seach method and still nothing is working properly, i get the number buttons and volume but no up channel and down or menu button. Need help

Dan

Some of these remotes are also made to run other components,so be sure to press the "tv" button and try the vol and channel again!

I used 0178 to program my universal remote. You can also try 10056, 10178,10864,10885,11756,10056,11758, and 11499. Then you can try by dropping the "1" from the front of these codes.
Most good remotes have a programming function if this does not work, where the remote will "learn" the proper code.
The actual button remote codes are as follows:
0 00117
1 00121
2 00119
3 00123
4 00116
5 00120
6 00118
7 00122
8 00245
9 00249
Vol + 00183
Vol - 00187

The solution is so simple!
Press the POWER (RED) button and the TV/AV button simultaneously - hey presto! the child lock will switch off and you will have your TV back working properly.

There is a button lock in the menu of the television. Using your remote access the menu screen and unlock the buttons.

I had the same problem. I hooked up the DVD player and then got into the set up. I used the add/erase feature to go through all of the channels. At channel 91, I saw the logo for the dvd player. I added that channel and now the dvd player works.

I had similar problem when setting up the YAMAHA remote control for my NEC LCD TV. At the end I found I did not follow the YAMAHA manual properly. Did you hold down the DTV/CBL button, and AT THE SAME TIME press the AV POWER for 3+ seconds? You should be able to "REMOTE SETUP OK" displayed in the front panel of the YAMAHA AV receiver. Hope this helps. BTW, only the TV POWER, TV MUTE and the numeric buttons work in my case.
