Re: 50PK350 Repair Log

Yeah thats a common issue on them boards, such a shame

Re: 50PK350 Repair Log

Ohh well, now you have two choices:

1. Sell it with lines out cheap.

2. Smash the living shit out of it in whatever way you want. (my normal choice)

Re: 50PK350 Repair Log

i would rather not sell it as is, i would rather keep the boards worth more money in parts tbh

i plugged it in expecting the click click click but it clicked then i saw the logic board led flicker my heart raced and sunk in secs lolol
never mind im always learning

Re: 50PK350 Repair Log

Re: 50PK350 Repair Log

Just picked one of this up,but the psu was a bit of a disaster,missing parts etc..
could anyone identify what ic 801 is?,it's missing,and from what I can gather it's a L6599AD,but the psu schematic isn't covered in the manual I have here...
google gives conflicting views over this chip!

Re: 50PK350 Repair Log

I have a 50 pj350 with the same problem and I looked up the fet and found two FQPF16N25C_NL and FQPF16N25C_ND with the same specs except one says tube and the other says rail. Does anyone have any idea which one is the correct replacement?

[ReeceyBurger123]

Re: 50PK350 Repair Log

Either will work.

Re: 50PK350 Repair Log

Thank you for replying so quickly and is there a better choice or should I just pick one?

[ReeceyBurger123]

Re: 50PK350 Repair Log

No worries, also either will work just as good. The specs are basically the same as well as the other parameters.

Re: 50PK350 Repair Log

Alright and should I use the 7watt 22ohm resistors or the 5 watt 22ohm? Just making sure because I have both

Re: 50PK350 Repair Log

I have this one as well as the 42 inch..... spooky, similar fault, stand by light, but when switched on it goes off all rails are up , the main board digital out is red, but no picture, I have replaced every board except, the ysus, got that to do next, if that fails it has to be the panel,

The 42 inch needs a new Z us, but I can't find one, it has been one of the most frustrating tvs ever...

Allen man calm down ! Take time to diagnose it. Does the screen light up in a dark room ? Doubt its the panel unless its cracked it so then its not fixable but if the panel isnt then it is fixable.

Re: 50PK350 Repair Log

As of right now I have had the 7watt 22ohm resistors on the power board along with a repair kit for a few weeks now. The tv will work fine for awhile then turn off and constantly click. Is this the fet, cap, and the resistors or something else?

Re: 50PK350 Repair Log

About to pick up a 50" LG Plasma on friday evening.... Not sure of the model number yet as they didnt know it or where to get it from.... Other than the Panel thickness difference, what are the pitfalls of swapping out the panels in these 50" models?

Symptoms of this one are that the set takes an age to come on... but i am told it can be anything up to an hour....

I am hoping and praying that the panel is the same as my 50PM670T that i stupidly dropped when i was decorating and put a crack in the corner of the panel.... It now screams when it comes on and then powers off....

Will Start a thread on the Repair when i get it picked up....

Re: 50PK350 Repair Log

If the panel is cracked thats not fixable. When Plasma panels crack you short the electrodes in the screen out which is why it hisses. You might have killed your sus boards by turning it on. Its trash basically

Re: 50PK350 Repair Log

I was absolutely gutted when i dropped the TV as it landed on the corner, i knew it was toast as soon as it hit the floor....

been searching for a faulty Plasma thats a similar model since cos as far as i am aware the boards in mine are fine.... once i find one with a panel thats fits then i am sorted and ahve my 3d Smart Tv Back up again....
