Re: Philips 32PFL6606T 32" LED no back light

Right then folks.......FIXED!!!! WHOOOO HOOOO!

took the complete screen out and the glare sheets,

1. set my meter to diode check and went through all LEDs at there test points = all were fine

2. went from the connector that plugs into the board to the first and last LED and check them set at a time (A1 to Led 1 test point and C1- to LED 14(something like that))

3. found that the connector block on 2 of the LED boards had come away from the board

4. re-soldered

5. tested again on diode setting to check the first and last LEDs were working to the connector.....BINGO

6. re-assembled and tested.....didnt work.......forgot to put the t-con ribbons back in for the screen

7. put ribbon cables back in.....powered up and there she was in all her glory!!

this looks like it could be a common fault because the connector blocks on the LED boards dont seem that great, the tv i would say is brand new, so i guess when its been delivered it must have took a small knock and bust it off its soldered joint

THANKS EVERYONE FOR ALL THE INPUT, WITHOUT THIS FORUM I WOULDNT HAVE DONE IT, I HOPE THIS TOPIC HELPS SOMEONE ELSE OUT IN THE FUTURE

I've got the same model TV with the same fault.

I read this very useful thread and attempted a DIY fix. Pulled the screen off and found the top LED strip connectors to be loose. Tried to re-solder them (a bit ham fistedly) and now when I power up all LEDs flash on for less than a second before going out again.

Can anyone help?

Thanks,

could it be a bridged joint on your soldering? pictures may help us to see whats going on and advise you.

its a very tricky job, i ended up doing it about 3 times, before i got it right and its still working now

i agree with vinceroger69.....sounds like youve got solder where you shouldnt have, try desoldering then redo it, be careful not to get the solder touching the metal plate the boards mounted on!

and make sure its solid before you put it back together, nothing worse than it coming off again on reassemble!

Hi guys, you were absolutely right! Had a bit of solder on the metal plate that the boards are mounted on. Re-soldered it and now the TV is working perfectly. Those tiny little soldered joints are a right pain to get a good connection without flooding the area with solder but hopefully they'll hold up for a good while!
Cant thank you enough for helping and posting this thread to begin with ... probably saved me the best part of 400 squid!
Thanks!
