Re: Mag LT916s Model 900p 19" LCD dropping like flies

Great News!!!! It works!!!
None of my caps showed sign of excesive heat, bulging or oozing...
First I replaced the 6 470uF Fuhjyuu 25v caps with the radio shack Xicon 470uF 35v caps. And still only powered on for 2 seconds. So then I proceeded to replace the other Fuhjyuu caps (the 2 x 100uF and the 220uF) with 3 more Xicons, and now it runs perfectly. Thanks so much for the help, I had bought this monitor on craigs list with out testing it first and spent $50, im glad it wasn't a total loss, I ended up spending...

these are the pics to the trnasistor... (i think the flat black thing with 3 progs at bottom,) on back of board the solder points are discolored where as all other are shiny

I just noticed one other thing on the inverter board, in the center, grounded to the heat sync looks like a transistor, (3 prongs at the bottom) when i flip the board over the 3 connections look a little tarnished and not shiny like all of the other IC connections. ???I can post a pic of that too if you want?

temprature rating says up to 85º C on the package, guess i should install a CPU fan on the back too. does tolerance have anything to do with its ESR rating?

Re: Mag LT916s Model 900p 19" LCD dropping like flies

BTW the radio shack brand are XICON the match the 470uf rating, and are 35v instead of 25v. it doesnt give a temperature rating but says ±20%

My caps look ok...?




this looks odd though, but looks almost factory... ?...

Re: Mag LT916s Model 900p 19" LCD dropping like flies

Re: Mag LT916s Model 900p 19" LCD dropping like flies

My screen comes on bright for 2 seconds just like everyone else, so I doubt it is my CCFL's but all my caps look perfectly fine. they are the crap ones so i guess iwill replace them anyway, im headed to the 'shack now. can someone please verify that the transistor on the bottom input IC board #13 which has 3 pins only the two outer pins are soldered to the board the middle one is cut, but the soldering job on the IC undernieth it does look like it was from the factory and done by a machine so this is probably suppose to...
