Good morning,
I am having a problem with my Philips 42" LCD TV Power Supply 715T2454-2. First started out with the 24VDC was missing, but with the help of this forum trend I replace IC TEA1507P, the 24 VDC is now there. But now I am having another issue.
Just powering up (plug in the AC) the Philips Power Supply 715T2454-2, using a Multi-meter I can read the 24VDC at connector J13, pin-1 and pin-2 but after awhile you can see the 24VDC dropping (counting down) 0V; this is with the Philips Power Supply still connect to the AC power source. Here is where it get a little con fusing for me. At first I thought the IC TEA1507P went bad again, so i decided to change it again the next day.
The next day for some strange reason I decided to powered up the Philips Power Supply again before changing IC TEA1507P, and using the Multi-meter I could again read the 24VDC at connector J13, pin-1 and pin-2, and after awhile "again" the 24VDC begin to dropping and I watch it counting down from 24VDC to 0V. After seen this I let the power supply sit for 12 hours and once again I was able to read 24VDC then watch it count down again.
Can someone here direct me to the source of the problem?
