Re: DELL GX280 problem-help!!

Finally found the culprit, the LCD screen, dell 1901fp. it may be capacitor issue again. LCD screen flicking then blank. I need to open and check it.

Just got one from auction, after power on, can see DELL logo, then screen has little flick and become blank after 10 seconds. Checked google, and opened the case found three nichicon 820uf, 6.3V caps near RAM slot, they all bulged. all other capacitors are fine, they are panasonic or rubycon with flat top. I replaced three nichicon caps with other three caps which are 1000uf 6.3V, 105C, but still has same symptom-blank screen after boot up.
Question is, do I need to sold the exactly same parameter caps? Do I need to sold a some kind of low ESR caps? Because the size of new one is even smaller...
