Question about Philips 42PF9431D/37 TV
Let's start simple. Have you tried, or are willing to try a new power supply board? I've had times where the read outs of all components are fine and finally before I was about to break it, I just stayed simple. I ordered a power supply replacement (new NOT "refurbished") and it corrected my problem. Secondly, your Ve is 110v?! That is on the sticker itself on the back of the panel? If so, and you were desperate, you could always run a line from the HOT main 110v to the XSUS that would supply the 110v needed (testing perposes only, not long-term use). Update me on what you find out.

Hi, i see all the time these people who think that every fault in a unit, is a capacitor, when it simply is not.
While caps do indeed go "Bad" just replacing them seldom will permanently fix anything. What most miss is that also there is "Other" damage done to "other' even seemingly disconnected componentry.
As said usually we have a fault, the cause, the damage done, and the co-lateral damage ALL must be found and repaired, or the fault will simply reappear, in one form or another.
Accordingly whenever we embark upon a repair the very first place we MUST start, as I tell all my students, is with the Power Supply.
Here we must check ALL voltages, as if they aren't correct here then NOTHING can nor will work correctly anyway.
So to check said supply one simply MUST HAVE a service manual.
