TV Volume goes up when channel is changed Philips 20S240

It sounds that the main system control memory IC is faulty. Replace it.

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.

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.
Discouraged yet?

I could still make out 68 over 2kv on the burnt capacitor. Replaced with a 680 pf 2kv that I bought at a local TV repair shop. works great.

hi there, you do have a power supply section problem, check the bleeder resistor which is 100K ohms or up. do some test. ty
