a lightbox!! ....brilliant!! (pun intended)
my brother owns a T-shirt silk screen biz (1988- 30 years), I used to do a lot of the artwork back in the true cut-n-paste b4 winblows existed daze, this would have been a cheap alt... good one ...
your LED TV's display screen puckered from that well placed beer bottle shot??, Or is it gonna cost too much to repair??...
simply need more light??
fret not frustrated friend, simply make your own shop light or area light from it.
I tried this as a joke, but dang it...it worked. I just gutted this 42" Vizio I found on the curb (made 117$ off it selling the boards on fleBay) then added a 24v PS from an ancient HP to it, kept the diffusers in it, and Ta-Da!! ...instant bright light source!!
added a couple handles and a kick-stand ... whole thing weighs...
Absolutely nothing.... 1st off, He's a close friend...
...& 2nd of all
He's now building another bar near this University... he's going to need someone to install/wire up the 15 monitors, multiple sound systems, camera/security system, and the LAN connected, multiple cash register system
and Internet ...
Got a tight-wad buddy (owns 4 bars, 3 rental properties) brought me 2 ancient monitors, a 13 year old HP, and an 18 year old Dell to fix, lolz I asked him, "[I]wazzup with these?, U have that deep a relationship with these that ya can't let 'em go??[/I]"
...and realize this guy drives a beat-up 1985 ford truck as well.....lmao
The Dell (E173Pf) lost it's backlights (happened to have one here, quick screen swap out, problem solved), but the HP (a vs19d) wouldn't even light up the power button. Soon as I had it apart, I saw the culprits....6 [B]Capxon's[/B] with the...

anybody knows where I can get these LED strips (not jimmys high dollar shop) drop me a PM, fleBays got squat, amazon's iffy, ali babba or whatever its called is scary,
thanks in advance
Re: P&F (Philips) 55PFL6900/F7 Turns on 3seconds then Off
Well after sitting here staring at this sipping the morning Joe, I ripped it down...can still sell the working boards after i probably kill this display glass...lolz
-First Picture-
There's a total of 8 strips, 4 w/ 7 LEDs, 4 w/ 6 LEDs,
layed out in 4 pairs of 2, (1 w/ 6 leds. 1 w/ 7 leds)
52 LED's total
CN1201 drives the middle two rows
CN1101 drives top roww
CN1401 drives the bottom row
-Second Picture-
Red stars indicate the burnout...
Re: P&F (Philips) 55PFL6900/F7 Turns on 3seconds then Off
well I rigged up a couple outside LED strips from another Set and plugged them into CN1101 & CN1401
I then took the end plugs from CN1101 & CN1401 and connected those into CN1201.... Hit power button and....see pics
Everything is staying on, R_J, you were spot on sir, bad/burnt LED array within the CN1201section....which normally I would rejoice, but as I stated, I have a 0% recovery when trying to replace LED's, I ALWAYS end up breaking the displays, I dunno if it's because I'm a bull taking...
Re: P&F (Philips) 55PFL6900/F7 Turns on 3seconds then Off
well if its LEDS, this TV's still screwed, I have the worst record of removing the displays and breaking the sh*t out of them...bummer. Guess the Boards going on flEbay I reckon
Re: P&F (Philips) 55PFL6900/F7 Turns on 3seconds then Off
ya, I resurrected a couple Nvidia GTX 8100's & a 9500 that way, just wish I was 100% sure this is the problem here, PS board seems to have all the right voltages, cant see nothing physically bad on this main board, those two huge heat sinks soldered clamped to the board tells me they had issues with that wonderful BGA solder technique here maybe ...
Re: P&F (Philips) 55PFL6900/F7 Turns on 3seconds then Off
I'm thinking it's a fakked main board, these huge heatsinks make me think it's a BGA lift failure
still not sure, don't have pinout voltages labeled nowhere nor a service manual
Re: P&F (Philips) 55PFL6900/F7 Turns on 3seconds then Off
Here's what I got voltage wise from CN657 off PS board
see pic for pin out
pin5=3.3v stby
pin6=0v stby - 3.3v power On
Pin8=0v stby - 3.3v power on
Pin9=3.3v stby
Pin10=3.3v power on
Pin15=12.9 stdby - 21v Power On
pin16=12.9 stdby - 21v Power On
pin17=12.9 stdby - 21v Power On
Pin18=12.9 stdby - 21v Power On
pins 23,24,25,26 all same= 8v stby - 12.8 power on
PS: All Power-On voltages drop to 0 when SPDIF light goes out...
