Question about LG Flatron L1951S-SN 19" LCD Flat Panel Monitor
I turned off the room power for a few hours, turned it back on, and everything came on as normal except this monitor. No LED, no indicator what so ever. Have trested cord, and there is power. Still, I changed cords, and changed outlets. No operation. Monitor working fine this AM. Someone mentioned a power board/inverter? There is also a slot in the back that has a lock symbol and "K" stamped in the lock...???
Can't find anything on this monitor.
Pls advise! Thank you!
I C Power PA192D Model 900G, Mfg Sep '05 19inch LCD
I purchased this monitor at Goodwill not working for $20. The 900G power light failed to come on and there was no video when turned on. To fix, first pull the 2 screws at the bottom of the back side of the monitor_ note this face is NOT removed by prying with a screwdriver like other monitors, it IS removed by sliding the face plate Upwards. Remove the LCD screws and remove the wires to the backlights carefully noting what goes where. Remove the metal cover and remove the 110volt power board. I found smoke trails under the cover and a swollen 470uf25v capacitor number C206, and replaced C110, C211 all were 470uf. Reassembled and found no change. Tore down again, used the ESR meter CapAnalyzer 88a and found C114 47uf25v to be 30% working, the volt ohm showed the cap to be good, that's why the ESR meter was needed. Replaced the 47uf25v C114, tested the large 100uf 450v capacitor, it tested only slightly under spec , could not find a 100uf at Radio Shack so did not replace it. So in this attempt the only thing changed was the 47uf C114. Reassembled and now works perfectly.
i'm not an expert at anything...x'cept maybe dumpster diving. God Bless
