Re: Sony Vaio VPC-SB26FG cannot power on

OK ! My MBX-238 - THE SAME shorted capacitor ! Thank you for hint. Now both power connectors are NOT shorted anymore. Unfortunatelly, its still doesnt power on. When i plug both black connectors to mobo i can measure 19v. But just when i plug DATA BUS connector (beside both power connectors) i lost 19v imediatelly and system not power on. What is wrong ? Thank you for help.

(just for info, im testing that mobo WITHOUT shorted capacitor as i have no spare for exchange, but i hope its not my source of problem)

Re: Sony Vaio VPC-SB26FG cannot power on

Hi all. I didnt find bad caps on my mobo, so i bought newone mbx-237. It seems to be ok, both black connectors are NOT shorted. When i connect, i can measure 19V with no prob. Unfortunatelly, system wont boot. When i press power, i can see cdrom short start (about 1sec) but imediatelly stop. No green light. But system is charging battery (one lucky point I can still measure 19v after it. May be BIOS is wrong. I have VPCSB, and bought mobo for VPCSA fyzically are motherboards identical, also both is MBX-237. Anybody has hint how to flash...

Please send it to this forum to everybody. I found another post [url]https://www.badcaps.net/forum/showthread.php?t=28627&highlight=mbx-237[/url] with simmilar dead problem. Im working on it may be also SN0608098RHBR problem... i will desolder it to check short problem.

My short problem is, that both power conector going from docking module - 6pin and 10 pin are shorted. so i cannot measure anything.Re: Sony Vaio VPC-SB26FG cannot powe... to everybody....

Re: Sony Vaio VPC-SB26FG cannot power on

Anybody find the solution? Now im also in the same situation, Capacitors near the small 6-pin connector are all shorted, so there is problem somewhere with shorted component. Capacitor? semiconductor ?. Please if somebody find the fix, let us know on this post. Thanks to everybody
