type in the code 319753 followed IMMEDIATELY by the MUTE button. The number sequence and mute button must be done within 20 seconds of each other. Once you hit mute a new menu will appeal click on CHANNEL INPUT (should be the third one down) then a new menu will come up and click AUTO PROGRAM at the bottom, this will go through all the channels (up too I think 90?) and unlock them one by one.
I wish someone would bring a suit against any of
these manufacturers using the term 'universal.' At best, they are 'multibrand' and, with the
proliferation of 'brands,' there never will be one that can rightfully claim to
be 'universal.' There may never be a code for your brand
available in every remote.
The instructions for searching for a code are pasted below stolen from another site:
steps for programing the rmc10 sentry really big universal remote
1, Manually turn on the device(TV, VCR, etc.) to be controlled. 2. Press and hold the code search button until the red indicator stays on, then release the code search button. 3. Press and quickly release the desired mode button (TV, VCR, ect.). The red indicator blinks off once. 4. Press the Channel up button repeatedly(up to 300 times) until the device to be controlled changes channel. The red indicator blinks off with each button press. If you accidentally overshoot the code required, press channel down button to backtrack through the library until device changes channel. Pressing Channel up changes direction forward again. 5. Press and release Mute to install code.
there are two things that can cause this, 1 there is a muting transistor on the bottom of the PCB that is a surface mount transistor that goes short. this is the channel mute transistor. when you change channels it is designed to mute the static between channel changes. if it shorts then it mutes. 2 the EE-PROM is defective and needs to be replaced. i'de go with the transistor first. if you are unequipped to do this repair have a tech do it.
Push in and hold code search button until it stays lit, then pushed the
TV button, it flashes quickly. Then hit the number zero once, then hit
channel up button until tv finally changes channel. Hit the mute button
once to get it to store the code.
I want to thank whomever suggested the following...it works. I had been trying for days. Here is the solution:
Turn off the cable box and hit the menu button on the universal remote. The screen with the closed caption selection appears. Scroll down to the line regarding subtitles and turn it off.
I know one code please try if it helps
1 press mute button once on remote control handset.
2 once again press &HOLD remote hand set mute button.
3 while keeping mute button pressed press menu button on tv set.
WHen I hit the mute button again to bring up the volumn the sound remains muted. I have tried all other channels, direct cable and even a dvd player connected. No sound. I unplugged all the boxes and tv and then plugged in again in a attempt to reset what might be wrong. Still no sound.
1 while operation mute button has got demaged or pressed more.
2 sound section might have gone defective in tv
3 no supply to sound section
4 or speaker defective or ic got demaged.
OK...I paid a whole $50 for an Apex AT2702 that had [undisclosed] vertical zoom, horizontal shift, vertical shift and width issues. Before I raised hell for the person who sold it to me, I decided to first exhaust all alternative solutions.
I found that in order to tweak these settings, you have to be in service mode and must have a service manual which I can email upon request.
BE SURE TO DOCUMENT YOUR CURRENT SETTINGS SINCE ANYTHING YOU CHANGE WILL AFFECT YOUR SET'S PERFORMANCE !!!
1-Reduce your tv volume to 0 2-press the MUTE button on your original tv remote [you'll see "Mute" in red on the screen] 3-AT THE SAME TIME, press MUTE on the same remote and MENU on the tv controls. This set your tv into service mode [there will be a red "S" at the top-center of your screen.
You'll need the table in the service manual page 47 where there are V-SHIFT, H-SHIFT, V-ZOOM, E/W WIDE default values that will need to be changed. WATCH YOUR SCREEN as you change the values to ensure you don't over do it.
If you have news ticker and sports scores issues, you'll want to be tuned to CNN, FOX, ESPN or whatever to see how your changes are applied. If you have tv guide problems then tune to that channel or press info and see what happens when you make the changes.
BE SURE TO DOCUMENT YOUR CURRENT SETTINGS SINCE ANYTHING YOU CHANGE WILL AFFECT YOUR SET'S PERFORMANCE.
This has worked for my set and you may attempt this solution on yours at your own risk. I'm no longer pissed off that I got a bogus tv because it now works just fine and I can see everything!
