Re: Philips BDS4231R/00 PDP S423D-YD07
It says PDP Module (S42SD-YD07) then has Model : S42SD-YB05 but is a Samsung Manufactured 2005
I suspect one of the Sustain boards.Last edited by notallbad; 05-30-2013, 04:08 PM.Comment

Re: Philips BDS4231R/00 PDP S423D-YD07
Any tips for what to look for or how to troubleshoot?
I have found a couple of swollen caps on PS bd in the Buffer power supply area, what should Va be reading, 70V?, the 2 swollen caps are located under the heatsinks (one each side) seen clearer in the second photo, pictures to follow:

Swollen caps could certainly cause your issue. Will await pics.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Philips BDS4231R/00 PDP S423D-YD07
Thanks, added pictures and also changed the suspect caps, both 680uF 50V which were slightly lower than rated and tolerance allowance 511uf and 323uf.
There are 2 boards that have constant flashing LED's I'm guessing fault indicators,
Samsung LJ41-03075A
LED labelled LED2000
and
Philips 3139 123 6093.1 Wk509.2
LED not labelled but its the only LED on the board that I can see.
The screen is also flashing on and off, this occurred before changing the caps.Comment

Hi, please attach your images to the forum not using external image hosts. It ensures the images will not disappear at some point down the road, increases security, and generally makes it easy for us. Thank you

Re: Philips BDS4231R/00 PDP S423D-YD07
Sure, sorry.
PS bd: LJ44-00101C PS-424-PH Rev 0.7
Connector SY
D5V measured as 5.1v
Vg measured as 14.93v
VScan measured as 188.3v
Vset measured as 196v
VS measured as 204v
Connector SX
VS measured as 204
Ve measured as 108
Va measured as 14.93
D5V measured as 5.1v
Cn8005 (Buffer)
Va measured as 69.4v
D5v measured as 5.1v
I could be reading the label on the connector SY wrong, is there such a thing as Vg or is that Va, in which case 14.93v is considerably low as Va should be 70v according to the label on the Panel which reads
Va 70v
Vsc -190v
Vs 209v
Ve 110v
Vset 198vLast edited by notallbad; 05-30-2013, 08:33 PM.Comment

Re: Philips BDS4231R/00 PDP S423D-YD07
It is in fact Vg and should read 15v so that is ok.Comment

Re: Philips BDS4231R/00 PDP S423D-YD07
Following this manual there are no error detection codes on the PS alarm board, the LED just comes on solid as do the 2 leds on the PS board.
i.e remove all connectors except mains input, place jumpers on relevant pins on all 3 connectors as indicated and power up.

If LEDs are on control board these are NOT fault indicators but in fact status OK indicators.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Philips BDS4231R/00 PDP S423D-YD07
I have found an issue which is the cause or at least not helping so shall resolve before proceeding further.
It appears that there is a wiring harness that goes to the logic board with burnt out wires, LVDS perhaps?.
Not sure I will be able to repair as its immediately next to the connector so may have to source another.Comment

Re: Philips BDS4231R/00 PDP S423D-YD07
So having removed the shroud it has revealed further damage to the wiring insulation.Attached FilesComment

Re: Philips BDS4231R/00 PDP S423D-YD07
Having repaired the wiring harness the tv has no change on picture.
Now I'm getting 8 blinks from the Error Bd on the PS bd, No Ve, and yet when I do the PS board test according to the Service Manual it all checks out ok. So it must be logic bd playing up.Last edited by notallbad; 06-01-2013, 07:01 AM.Comment

Hello,
I've got a really strange issue with the speakers on my Philips 43PUS7506/12. It makes this awful loud buzzing now. It happened after it was attempted to be wall mounted - I think the back got squeezed and something broke.
I thought maybe the speakers got damaged, so I replaced them - no dice.- Using the internal speakers, it always happens.
- Using the headphone jack, it never happens.
- Using the digital/optical out with a soundbar - it happens after about 2h/movie runtime - it's never as drastic, it just pops in and out, but I didn't want it to damage the sound bar

Hello Team,
New issue on LCD panel where I need to find out the cause and the potential solution.
This is on the Philips 50PUH6400, the LCD panel is an INNOLUX V500dk2 xrs1.
I have image, on the right side, the image is more or less normal even if there is a small blur on edge, on the left there is an issue.
When moving up and down in the menu on the right the image is slow to disappear, and is darker, like red/brown.
I've checked voltages, no issue found comparing right and left side of the panel driver.

Hello partners.
Could someone tell me how to make this Philips TV source work without the mainboard being connected? The model of the board is EAX65423701 (2.1) and the model of the Philips TV is 40PFH40009/88.
The TV is dead, there is no standby light, however there is a voltage of 12v on the pins ( included 12v VAU ) and 3.2v on the PS-ON pin (see photo) when the power board is connected to the main board. If I disconnect both boards I only get 8 volts on 12v pins. I would like to rule out a fault in the main board by making it work, but so far no one has been able to tell... -
i have a philips for repair 55pus7909/12
fault is no display but the white logo philips lit below of the screen
No display
No backlight
no sound
power supply the standby voltages are ok
Any Help regarding this problem?
Thanks -
TV is Philips 40PFT4101/12, power supply 715G6934-P01-000-002M, motherboard 715G6947-M002-000-004Y (703TQGPL068).
The problem is that when it is plugged in, the TV turns on by itself, the Philips sign appears, the backlight turns on and off a couple of times, and the TV turns off, and so it repeats itself in a circle. It does not respond to the remote and nothing is written on the screen, the red light does not blink.
A few weeks ago, it used to turn on by itself about once a week, but after that it worked, now it doesn't work.
I checked the power supply, voltages are fine,...
