Philips LED TV 40PUT6400/12 With Powerboard 715g6677

Hi people.

got another TV i'm stuck with

Philips LED / LCD panel Model 40PUT6400 NO POWER OUTPUT

I have done all the basic testing, fuses, ac input / dc output etc.

I found no DC out to the main board, but I have never worked on a Philips TV before, and I'm not familiar with common faults on their boards.

Before I really rip into it, are there any common issues with philips TV power supplys?

thanks for your help

It's always a good starting point to have some photos of the circuit boards as well as the measurements you have taken ie those in the red box.

Pin number, Label, Voltage
Pin 1 BL_ON xxVolts
Pin 2
Pin3
etc

HI
yes i have checked all the pins, I get no DC voltage on any of this section of the board, all the diodes seem to be OK, fuses OK, rectifier seems ok (on a dead test).

I can do compoent testing but it takes time, hoping to just be pointed in the right direction of common faults on these boards if there were any

thanks

Looks like it's going to require some work, do you have any lights on the front panel coming on as in standby light if tv is totally dead, usually the standby circuit of the powerboard is where to start. Maybe try unhook everything from the powerboard then plug power cable into powerboard and see if you at least have the standby voltage. Good clear straight on pictures of each board and one of the whole back as requested will probably get you more help, so the forum can see what they are dealing with as remote troubleshooting is not easy.

May not be your problem but one example there of a dead set repair which had one bad electrolytic cap: https://www.youtube.com/watch?v=UtVtd62owGE

If this helps anyone just done one of these boards with exactly the same problem - no voltages at all - turned out to be D9311 ( SK510C )
