Check for an HDMI port
Check the back of your television for an HDMI port and refer to your owner's manual for your television's resolution. A resolution of 1080p offers the highest quality.
Most PS3 systems support 1.3 HDMI, but older systems may need a software update from the 1.1 or 1.2 version.
Disconnect all the cables and adapters from the back of your PS3, and then unplug your TV to reduce the risk of shock as you work.
Connect HDMI cable
Connect the HDMI cable. Reconnect the power cables on both the TV and the PS3 system.
Hold power button
Hold down the power button until the PS3 beeps and continue holding it for an additional five seconds until the system makes a second beep.
The Playstation 3 should detect the high definition cable and automatically adjust the settings to give you the best picture and sound possible.
Test the connection
Test the connection. If the HDMI cable isn't working, turn everything off and reconnect the original cables to manually change the settings.
Adjust the settings
Turn the system back on, select Settings, Display Settings, Video Output Settings, and then HDMI. Repeat the process for your Audio Settings. You can now experience your games with the highest video and audio quality available.

It is possible that the Low Voltage power module is defective, however I would first check the High Voltage power supply for bad capacitors (they tend to go bad first). In fact check both boards for bad capacitors (they will look puffy in appearance if they are really defective).
