Re: Help With Bad Cap ID on LG M208WA
hi,sorry for late reply. wizard,the cable is ribbon style,i have been carefull with it.i took the cable off and checked for continuity,it tested ok.I havnt flexed any boards or bent any other cables.I didnt put the whole thing back together with screws i just placed everything loosely into the back cover to test,it was easiest way.Plainbill,il post some more pics and do more tests tomorrow.

Re: Help With Bad Cap ID on LG M208WA
Ok , ive measured the voltages.I only have a analogue multimeter though,i`l borrow a digital one if it has to be very accurate. The 5V voltages measure very very slightly over 5V , and the 15V measure very slightly under 15V .Leave a comment:

Re: Help With Bad Cap ID on LG M208WA
Ive reread what you said wizard and done a bit more research.To be honest most of what i read the first time went right over the top of my head.Sorry just laziness on my part. So , i need an inductor (coil with ferrite core),and a medium current diode.Am iright in saying that the 002A on the inductor means 2 amp ? and can anyone tell me what the DB712 means .Ive done a search on farnell and digikey and found nothing.thanksLeave a comment:

Re: Help With Bad Cap ID on LG M208WA
I put everything back together and im getting a picture now,vertical coloured (colored) stripes,backlight is nice and bright.Ive repaired a few laptops before and id say it was a bad inverter,i dont know why it wouldnt even show anything before,maybe a bad connection or something.Ive turned it on from hot and cold,does this now rule out the power board and backlight .Leave a comment:
