Question about Philips Magnavox 27MS343S 27" TV

TV Volume goes up when channel is changed Philips 20S240

My father in law has a Philips TV, model 20S240 C122. When he changes the channel on the TV either with the remote or by changing it directly on the tv, the volume briefly (for about 1 to 2 seconds) increases significantly, then returns to normal. Also when the mute is pressed (again, either by remote or on the unit) the volume goes to full blast.

What could be causing this? Is this a relatively easy fix? Does anybody know where I can get a service manual for this? My father in law talked to a tv repair shop and they said the IS sensor (I think he meant IR sensor) needs replacement. Does this make sense?

Thanks
Mike

I don't think the IR sensor has anything to do with it. It sounds like a surface mount micro processor to me...

Phillips 19 inch TV/VCR combo --no remote--can't change channels


Hi,
I cannot be sure of the exact model but... Press and hold the TV's volume up and volume down buttons simultaneously. On many older televisions, this opens the device menu without the use of a remote. Otherwise, use the menu button, which you can navigate in a similar fashion.
Also, somewhere should be an input button. Press it multiple times times to switch between various inputs (the input must match whatever input you are using). Usually after these menus are opened you can use vol up vol down to change things.

Philips Projection TV Bulbs need changing


Buy a new television. The "bulbs" are actually small picture tubes, also referred to as CRT's or guns. There are three of them, Red, Green and Blue. The cost for the tubes alone will probably exceed the original purchase price of the television. If the new tubes do not have the lens assembly attached, then you will need to transfer the old ones. This involves draining, cleaning, and refilling the coolant chambers. Once installed in the set, there is a series of mechanical and electrical adjustments required, to get the picture aligned or converged. This procedure is not recommended for the inexperienced. If cost and time are not an issue, then everything can probably be found on the Internet. Simply search the web for your model number. You will need the remainder of the model number first. There are at least eight models starting with 46PP9302. You are missing three additional characters.
