Have a Philips 50pfp5332d plasma, that will not power up fully. Its not the ssb board, all voltages on power supply are good except for the VG voltage which is erratic. I am getting 7 blinks on the led on power supply, manual says "PFC" protection. Where do I go from here?

Re: Philips 50pfp5332d protection led
Will you post a picture of the top and bottom of your power supply? -

There is no bulging caps on the board, I have checked about a dozen times.Attached FilesComment

Re: Philips 50pfp5332d protection led
Try unplugging the y-board connector from the power supply and see if it turns on without the led flashing. Is the led on the front of the tv flashing or the led on the power supply? It also appears that some caps on your board have been replaced. Did you pick this up second hand?Comment

Re: Philips 50pfp5332d protection led
Well I have tried that with both the y and x boards, sometimes it will power up othertimes it won't but I never get a picture on screen. On the logic board I have the 2 steady leds on as needed, one stays on until another starts flashing. The flashing led runs for about 5 seconds, I can hear power charging the y sustain and display flashes for a milisecond then it all drops out. Sorry Im not in around the tv to give you exact led number locations. It does not always go into protection, but when it does I get flashing light on front and power supply. Yes picked this tv up broken, got it home worked fine for two weeks. Now I got this issue.Comment

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump
One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy... -
OLED Cells over all OLED brands are easily its drooping more currents will be increase which it trick the SOS signal which T-CON driver boards will send to the Mainboards... the NVM software on the Mainboards will shutdown the PSU..
not all fault at OLED are bad-- some issue can remain working with minimal issue at displaying generate
Philips OLED TVs. we can switch the protection code to off via binary.

I have been working on this concept for quite some time now with limited success but recently I found a switching power supply that is setup for the voltage that this soldering station needs to operate at however it also needs part of the secondary circuit from the original switching power because you need several voltage rails
I once tried to get a ZD-915 desoldering station to work on a 18 volt battery power supply but unfortunately things did not go well but I did find a work around but I might try this idea again but going at a little differently more about this another time...
