Re: LG 37lc55 turns on few minutes later screen goes out
Damn not good anyway to be 100% sure its panel failure? Would explain why even with new main board the problem persisted

Re: Capacitor values for eay3306450
C225 10 v 2200uf
c216 10v 470uf
Lastly C151 450v 82uf
I thought I'd got one or two wrongLeave a comment:

Capacitor values for eay3306450
Hi guys I have a stupid problem after rushing in on a TV fix I changed some bad caps but in my haste and stupidity I didn't get the right uf ratings, so I'm hoping someone has the same board or can point me at where to look to find the answer the ones that stand out are
C204-205 both at 10v 3300uf
C208 50v 470uf
C207 35v 1000uf
C303 35v 470uf
C222 35v 680uf
If anyone could confirm which are the wrong values would really appreciate it -
Re: LG 37lc55 turns on few minutes later screen goes out
Anyone have a layout for this board as can't seem to find one to know which capacitors to changeLeave a comment:

Yeah brand new tcon I'm stumped unless main board I bought was dodgyLeave a comment:

Re: LG 37lc55 turns on few minutes later screen goes out
Thanking voltages of pins they seem to fluctuate a little
12v = 12.2-12.4
3-4v = 3.2-3.7
6v = 6.1-6.5
19v = 18.5
19v =18.3-18.7
These are the same when TV is working as to when its on blackLeave a comment:

Replaced the main board inside the TV but still the picture slowly brakes up then goes to black any ideas?Leave a comment:

Have you checked fuse? They seem to get damaged a lot and the connectorsLeave a comment:

Re: LG 47LM7600 Backlight works but no picture
Just my 2 cents have you tried seperating the upper and lower board to try narrow it down and tested all voltages?Leave a comment:

Re: Samsung le37s86bd
So just replace full thing? or possible to find what cause the problem?Leave a comment:

Samsung le37s86bd
Hi guys me again, I've been given a Samsung le37s86bd with no back light I've done the flash light test and there is picture just zero lighting so taken the case off and going to test power to back light board. Everything else looks good on the board but any other things I should check? I'll uploads pictures of boards shortly just -
Re: LG 37lc55 turns on few minutes later screen goes out
I took all voltage from the pins and they're all out by around 2volts higher then stated on the board also found few diodes and resisters that aren't working so going to swap them out and see where it gets meLeave a comment:

Re: LG 37lc55 turns on few minutes later screen goes out
I've decided to come back and sort this I'm testing main board first ex38425201\13 resistors on r100 is coming back shorted or open not sure on term what else should I check?Leave a comment:
