Toshiba PB8014-1 no vertical deflection.

Look at that blue line! The day this happened I could small something burning.

And look what we have here! one bubbled up LA7838 vertical IC

So I put a new vertical IC in location Q306 and turned the monitor on and still no vertical! Tested pin 8 for 24 volt power and nothing. I tracked the problem down to a fuse FQ03 you can see the empty spot for it in this picture.

Fuse FQ03 125v 5A brand SOC open.

Wanted to fix this monitor today so I rigged up a new fuse with a connector from Radio Shack.

After installing the new fuse wa la that monitor is working again!

Components changed two, cost $5.00
