Re: Lg 23lx1rv

Thought I would update. Caps arrived in mail today and I went ahead a replaced the two that I suspected were the cause. Turned it on and voila it's fixed.

Thanks again selldoor for the help and PlainBill for finding the fix.

Re: Lg 23lx1rv

Went ahead and ordered the four since price isn't really an issue. Now just have to wait for them to arrive.

Thanks again for the help.

Re: Lg 23lx1rv

Thank you selldoor for that great tutorial. Had some time to check the regulators and their values were very similar to PlainBill's. The 3.3V regular was reading a 3.29V but the 1.8V regulator was reading 1.745V a tad bit less than what PlainBill was getting.

If I'm not mistaken I believe the 47uF 16V caps that PlainBill replaced include the cap under the bottom left corner of the gm5221 chip and the cap on to the bottom-left of that one. Looks like there are 2 traces coming out of the 1.8V regulator to those two caps.

Please let me know...

Re: Lg 23lx1rv

Oh sorry, the issue looks to be the exact as what Plainbill was experiencing. I meant to ask where to find the power regulators so I could test them and in turn find the correct capacitors to replace.

I have used digikey before but I would like to test the regulators before buying the caps.

Here's a pic of the power board in case it is needed:...

Re: Lg 23lx1rv

Hi guys I'm trying to find the capacitors that I need to change for this fix. I found the gm5521 chip but not sure which caps are the ones needing to be changed. A bit of a newbie so any help would be much appreciated.
