Re: LG L1717 Monitor cap failure

ah okay, i was suspecting those parts because they look different from all the board, there are alot of blue thingies but none has that glue and i thought maybe it leaked or something. Ill just see what i can think of next. thx alot for your advice and for your time ! ill try finding a multimeter

Check and reseat the cable between the LCD panel and the logic board, if still problem, then check the SMD fuse on the T-CON board of the LCD panel assembly.

ok first of all thank you very much for the reply, i appreaciate everyone's patience with me. I managed from a no power monitor to get to power on but only white screen. I looked on the board then and i saw some fuses. I replaced some, some i just wired. Anyway now its powering on and its showing rainbow on display. What next ?

Re: LG L1717 Monitor cap failure

Wire replacing fuses is not the way to go. The fuse is there for protection and if the wire unsolders and drops onto the circuit - finished.

Have you got pc connected?
If you move the LVDS cable do the lines move?

Sadly no, i do not have a multimeter, i just moved in a new rent place. Also by foamy i mean leaked i guess. I did manage to take pics of the board, the c102 and another leaked one which says th101. i also took a pic of the whole board. im attaching them. Thx for your reply !

I see your c204 is bulging, maybe thats where your problem is.

it was indeed, i did buy a new one and replaced it. after replacing, it did power on but it was showing white only. i replaced some fused and now its showing the rainbow (attached earlier in the thread). I guess the best thing right now would be buying a multimeter and see maybe i missed some fuses, i have no other idea

The fuse on the T-CON Blown? It looks like the panel is damaged by short circuit.

Re: LG L1717 Monitor cap failure

hey guys, would this be a good setup of the multimeter to verify the continuity in the fuses ? i really wanna fix this monitor it became a goal thx !

Re: LG L1717 Monitor cap failure

Just a quick message to say that LG L1919S is the same kind of construction as the 1717. Toughest part of the job is removing the bezel, it's very hard to pull off, don't hesitate to pull hard. I broke some of the clips with no impact on remounting.

I just changed one cap: 1000uF 16V. The replacement one I found has same length but much bigger diameter, just enough room for it coming in contact with a nearby heatsink. It works fine now.
