I have a proscan 42LA45H 42 in television that has started making a buzzing noise from the back. What is causing this, and what do I need to do to fix.


Hi
If picture and sound is Ok, and only this buzzing sound is heard from the back of the TV, It should be due to core soose of some ferrite cored transformers inside, especially to the power supply regulator board of the TV. Open the back cover of the TV and swtich it ON. Listeen very carefully which transfromer makes the buzzing noise. Just trouch and press the core of the transformer suspected with some non-cunductive material like glass rod, or a stick of dry wood. You can identify the transformer that makes noise by this way. After identifying the exact transformer; switch OFF the set, unplug it from mains socket, apply some "Super Glue" like fast boanding glue to the joint of core of that transformer. Allow sometime for the glue to set. This will solve the buzzing sound problem of your TV. OK

Proscan 26LB30Q Vs PS2 = HELP


The red white and yellow cables are composite connections. The red/green/blue connections are component connections.

The playstation's composite connections consist of two audio connections- red & white, and a composite yellow video connection. The TV's white connection is the audio, and the red/green/blue are component video. You need an adapter that will connect the one yellow(composite video) to the three red/green/blue (component video) connections
