Probes touched together what do you see?

Re: Need help figuring out whats wrong with my LG 50PJ350

It stays on 1 unless i can manage to bring the very tip of one probe to the very tip of the other probe,and then it will flash random numbers between 80-180

Your meter is faulty then. Replace it.

Re: Need help figuring out whats wrong with my LG 50PJ350

That, or your probes are corroded. Try other probes first.

Ok so I brought the TV to a TV repair shop and they are saying that there is 10 bad resistors on the PSU and that they cant solder on new resistors,they have to replace the whole PSU , for $170.....does this sound like something that would happen with the signs I listed?Is it that hard to solder on new resistors?

thanks

Re: Need help figuring out whats wrong with my LG 50PJ350

Sounds like utter nonsense.
It's not hard at all to replace resistors...
10 bad resistors?? I'd be very surprised if that were the case.

Re: Need help figuring out whats wrong with my LG 50PJ350

Well needless to say after a bunch of B.S. the repair shop came up with,They said they made a mistake and there was only 2 defaulted resistors( The exact 2 resistors tom mentioned at the beginning of this thread before I even took the TV into repair, Good call tom!) ... I decided I didnt want to do business with them so I told them dont repair it,and they only took $70 instead of $170...

Well I know the parts I need,and that I need to remove the current resistors and solder new ones on.Can anyone give me any guidance on the removing/and soldering of the new parts.First time doing this...if I need to get behind that psu how do i disconnect the cables that prevent you from pulling the panel back very far?Whats the easiest way to remove the current resistors?. here is the pic of the panel and the 2 resistors in question (as posted previously in thread)

thanks

I bought a 60 in. panasonic,so this is going to be my backup tv

Here's the part you'll need.

I would not give that TV shop any further business if they lie to customers like that, and seriously, it takes less than 5 minutes to replace those...

Enjoy the Panasonic. Nice choice. This LG is also pretty decent apart from some reliability problems, though more reliable than Samsung... :/

Re: Need help figuring out whats wrong with my LG 50PJ350

Ok thanks.Any tips for removing the current resistors?

[tom66]

Re: Need help figuring out whats wrong with my LG 50PJ350

Soldering iron & fresh solder applied to each end for a few seconds, wiggle the original out slowly, swapping from side to side with the iron (no more fresh solder once the stuff starts to melt well.)

Re: Need help figuring out whats wrong with my LG 50PJ350

Ok thanks , and will I be able to do this without dismounting the psu?

Hi,
I have lg 50pg25. It has similar problem. Power on for about a couple of seconds to a couple of minutes then shut off. Could this be same problem?
It has three white resistors on the top right corner.

You will need to remove the power supply from the chassis to do work on it.

Unlikely -- see my prior post.

Re: Need help figuring out whats wrong with my LG 50PJ350

Hmmm..you see those sets of insulated wires going into the psu ?How would you discconnect those so you can take the psu off the TV??

When I unscrew all the bolts holding the psu down,the wires are the only thing preventing me from pullling it all the way off.

Press down firmly on each side of the connector and lift it out. Do not apply excessive force.
