Got this 8 years ago for 10 euros, seller said he tried to repair psu and destroyed it but panel is OK.
Used panel to fix another LG 20" model LG Flatron L204WS that found near dumpster with broken panel.
Used panel of L207 on L204 and kept L207 for parts.
1 month ago troubleshooted Samsung 20" I also found for free, turned out the Samsung had mainboard bad. Tried to reflow, no change.
So, I decided to use the panel of Samsung and try to fix the LG L207 too.
I attach pics after repair of the power supply that the previous owner tried to fix and did more damage than good.
Noticed that he recapped entire psu board with Jackcons
And to make it worse, he installed the small starter cap with reverse polarity
So, I removed all the Jackcon capacitors and carefully inspected board for broken traces / cold solder joints / ripped off smd components / lifted pads etc, then recapped board using a mix of good caps and mediocre caps like Teapo and Taicon.
I also tried to reinforce some solder traces that act like heatsinks, preventing PCB from overheating.
Monitor works!
