    Sorry meant to say that on screen display does come on and using remote does 'fight' the volume going down and cause it to stop at whatever volume it is at when volume up on remote is pushed

Well depends on how far it turns the volume down as to what the cause is and if the volume bar on screen display comes on when the vol. goes down. if it just goes down a little you probably have the "smart sound" setting turned on in the audio menu turn it off and see if prob. goes away. if the vol. bar comes on the screen whenever the vol. goes down the you most likely have a bad button on your front panel and it doesn't have to be the vol. down button. it you think it is the button it would need solder work to be changed most likely shop job.

    Yes this is a common problem in this model and it's almost always a bad tact switch, omne of the front diplay buttons,it won't seem bad to the touch but they make internal contact intermitantly and cause an outward symptom like the volume going down. confirm for me you do see the on screen display bar for the volume going down.also if you try with remote to turn up while it's going down does it seem to fight to try to turn back up the volume usually just causes the volume to stop as long as you hold the vol/ up button down. please confirm these things for me.

    OK you have a bad switch very common problem in this model and very repairable--when i do these i change all 4 switches on that panel.. now the model number you gave did not come up on the philips web site. I am an auth. service center and have full access to manuals and parts listed. my guess was 27pt6341/07 if that is your model# then the location numbers for the switches called "tact switchs" you will be able to use the model number and location number to order parts from a dist. vol+ loc#1011

    VOL- LOC#1012 CH+ LOC#1013 CH- LOC#1014

    These parts are solder work to change. Good Luck

    ps if you confirm you gave me a good model # than it may be an overseas model not listed on the North American web portal which ever when you order parts use your confirmed good model number and location numbers

Remove all batteries from your remotes. Unplug the unit for several minutes. Plug unit in and use the controls on the set to turn it on and adjust the volume. This will eliminate the remotes. They could have a button stuck. If this does not work you may have a legitimate problem and need a tech.

Usually on a universal remote (after programmed) the volume is controlled by pressing the cable button then adjusting the volume. When you turn your tv on by pressing tv power---then flipping through the channels by pressing cable--channel up or down.

I had this problem once. unplug the TV and place it on the floor with its face down. Make sure you put it somewhere where it wont get stepped on. And let it be like that for a day or more. This happend on my old tube tv, not sure what type of tv you have.

How to re tune a 20 pt 4673/75R Tv without original remote. Thanks John

That has a PLL tuner that retunes everytime you change channels so there is no fine tuning.

If it is out of tune, then the tv needs repair. If you need to switch from Air to Cable or Cable to Air and then Autoprogram, that would be in the menu.

The model number does not appear in my Philips cross reference. Generally, the Menu is a seperate button or pressing the Volume Up and Down together until the Menu displays.

To make it easy for you - you should have original remote.
Then through the menu look for channel set up then make sure you select cable or antenna then you do autosearch(sometimes called autoprogram).Unless the tuner is defective,you should be able to program withe the original remote.

Instructional program for Magnavox won't turn off, and can't use the remote

I just did a search today because my kids have the same tv. I found out if you push the volume + and channel + at the same time for about 5 seconds, the tv shuts off and resets. It is in factory mode. Give it a try, if that doesn't work try volume - and channel - at the same time.
