Re: LG 50PJ550 Clicking

Ah that might explain it flocko I had a few black lines when I Resinstalled buffers but sorted that by finding a few ribbons out of line so fixed this but a few days later the white line appeared I'll look again

Thanks

Re: LG 50PJ550 Clicking

Hi Lee check Y buffer ribbon that lines up with it and give it a good clean,it could be Y buffer but would normally show as a dark line.but could be on its way out?

Re: LG 50PJ550 Clicking

The TV is still working fine but started to develop a faint white line going across the screen I know when I fixed it the to had a bit of image burn
So do you think it's the panel ?

Re: LG 50PJ550 Clicking

Nice one

Re: LG 50PJ550 Clicking

Well done Lee, did you upgrade to the ICE3BR1065JF current mode controller. I fit these now in all my power board repairs, LG and Samsung

yes mate thanks

Re: LG 50PJ550 Clicking

Update:::

Replaced all parts as described by Flocko and tv up and working now

Thanks

Re: LG 50PJ550 Clicking

The SMD resistor 680K (4) 620K(1) and 560K(1) IC 701 MC81F4316 and use 3BR1065JF gives it more head room, and is the same as used on Samsung power boards so always at hand

https://KIT363 EAY60968701 EAX613971...on=ViewProductThanks flocko was going to try this kit

Re: LG 50PJ550 Clicking

put in a new 3BR regulator and replace IC 701 also check on the back of the board there is a string of SMD resistor head to tail (in series )just by the IC about 11or 12 of them,I have had problems with these in the past, worth a look Flocko

Re: LG 50PJ550 Clicking

its strange because 3BR1565JF Regulator is showing as shorted again and the diode as well but i know if i remove the diode out of circuit its fine

Re: LG 50PJ550 Clicking

ok I've jumped my board on and it's RL-ON to 5v stby.

all voltages came up.

jumped RL-ON to 5v no voltages came up just one click

Re: LG 50PJ550 Clicking

Sorry Hamie your right i was measuring the legend wrong with main board unplugged RL-ON is reading 0 volts but with main board plugged in then the tv clicks RL-ON is reading 3.9 volts then drops to 0 Volts

[Hamie]

Re: LG 50PJ550 Clicking

You sure you've measured your voltages right?

I have a working board for this model, if the mainboard is unplugged RL-ON is 0v

Ac-detect, the pin opposite it, is close to the voltage you have stated you have RL-ON.

Re: LG 50PJ550 Clicking

RL-ON to ground.

Vs ON to 5v stby.

Give that a try.

hi hamie do you mean jumping

RL-ON to ground and M-ON to 5v stby ?

[Hamie]

Re: LG 50PJ550 Clicking

RL-ON to ground.

[sordids999]

Re: LG 50PJ550 Clicking

4.14 Volts

Re: LG 50PJ550 Clicking

What voltage do you get on RL-ON?
