Question about Apex Digital PF2725 27" TV
Picture and dvd player work fine.....there is no sound....i have tried the function key with the mute button...nothing seems to work
please help...i am going insane !
If the set is still in warranty I would get a shop to fix this. If not and the set is over 5 years old and had a good picture in the past, I would suspect failing capacitors in the vertical circuit. On older sets, you could adjust this out with controls located on the main circuit board. With these newer sets, you would have to adjust it via service menus using both the remote control as well as the video button on the TV itself. For instance, on a model PF2720 which has a CH-16CD chassis (may or may not be the same as yours) you would have to first decrease the volume to zero then press both the mute button on the remote control and the video button on the TV at the same time to get into the service menu then by using the menu select buttons on the remote control go down to where the symbols S2 VAM comes up, and that setting when adjusted would vary the vertical height of the picture. It might also be necessary to adjust the VSH to shift the vertical up or down so there are no lines at the top of the screen and you could still read the bottom. When finished, you would have to press the timer(?) button on the remote the key that looks like an apple with a stick in the center to get out of the service menu. Note that if you try this, do not tamper with any other adjustments, or you may never get the set back to normal again. Since I do not have the instructions for your particular set, you may not even be able to get to these adjustments by using this method. If you have a TV shop nearby, they may be able to do this for a nominal charge as they would not have to take the back off the set to adjust it. If you do decide to do this procedure, write down the values before changing them in case you have to back track to where they were.

Sounds like the power supply regulation has gone high volts, and the screen is blooming because of it. I suggest getting a tech to look at it, will probably have the usual issues of capacitors failing in the power supply. Cheers

Press the (function or F) button and the mute button at the same time. This will unlock the screen and allow you to view the channel as desired. • If your TV asks for a 4-digit code or password please enter 3308 or 6688 to unlock the screen or reset any preset rating levels..

Here's how to fix it - I have a PF 2425, and it's driven me absolutely up the wall. Videogames are useless because you can't even see the crucial gauges etc. Likewise, subtitles and credits in films are cut off. it's ridiculous, especially considering how easy it is to fix (if you know how).
1. Decrease volume to 0.
2. Press MUTE so the tv says "MUTE" onscreen.
3. Hold MUTE on the REMOTE and MENU on the TV simultaneously until the service menu appears.
It's important not to screw around here too much. Use your arrows on the remote to navigate, the first option likely will say "MENU.0" or something like that. Use that to flip through the pages. What you're looking for are values like V Zoom, V Scroll, etc. Same goes with the H values. Toy with these a little and you'll be able to get the tv scanning perfectly.
I can confirm this worked for me! So good luck.

You may have bad solder joint inside the remote and especially on the l.e.d at the front, happens often(remote dropped etc.). If you have a soldering iron you can open it a make a round of the solder joints, it should fix your problem. Hope this will help.
