Hi there, If your psu is making sounds I would try blowing it out with a bit of air. If that doesn't help I would replace it since there are no servicable parts and with out properly discharging the HV components it is very dangerous to open the unit up.

Hello there! Got an old Philips plasma tv 42PF9945 with Samsung power supply LJ44-00049A that seems to be dead. LED's are off, there's no stdby voltage, all it's doing is a very silent sound...

Kris are you sure of that model number... That supply is most commonly found in a Philips 42FD9935/17 but they could have revived it for your model too I guess, neither were high-end units.
You would need several pieces of test equipment to properly check the supply and if you're not a tech I doubt you would have made such an investment. Best advice take to a qualified tech or just replace the supply. Try ModusLink, Tristate Module or Shop Jimmy for a replacement.

I have problem about over heating of my p4 procesor specialy in summers, my motherboard is 775i65G ... in summers the temp. of processor reaches 62 degrees and cpu fan runs on high rpm which results in...

all fans in time will get louder. The power supply unit has a fan and if you don't already have a fan on the CPU then you can add one to help cool it The fan in the power supply can be upgraded to a quieter one if need be. Any dust on in the case on on the circuit board will retain heat so getting some dry air and cleaning them should be performed. Be sure to ground yourself to the medal case when working with the case open.

Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.
Please post back what you find. If the tech installed a used power supply, it may be bad also. 3 years are typical for capacitors to go bad.

The set has developed a short either in the power supply or the horizontal/high voltage circuit. The power supply makes a weird noise when it gets overloaded. This can get complicated so have a repair shop check it out for you. Thanks

Compaq Armada e500 refuses to start!

An immediate boot fail normally either indicates a flat cmos battery or a faulty processor. My advice is to take to a qualified repair shop, as notebook are not as easy to work with as desktops and finding the cmos battery alone can be a headache.
