Hello dear people.
I have a Philips 43PUH4900/88 tv set that a few days ago blew some of it's backlight LED's. Other than that, it worked all right. Before i dissasemble the panel i measured that the PSU output voltages checked ok. I ordered replacement LED bars and after installing them, the tv set will no longer power up. The pilot lamp on the front stays dark. I measured the voltage on the main filter capacitors C9802 and C9803 and they read 320VDC. I think that's a little low. I think it should be around 360-370VDC. The output reads 0V on all pins. No standby voltage, nothing. The PSU model is : TPY 715G6677-P02-001-002S
Here is a link to download the PSU's service manual from EleKtroTanya
It is weird that it stoped working right after replacing the LED's. What can i say...
What sould i check next ?
THANK YOU !
