why wont the focus work on my sony vplw400q?
Your cry for help doesn't say whether the focus ring turns or not - maybe because the focus mechanism is stuck...... you could try a little dismantling to investigate, equally useful if the ring is turning but the focus is not changing. If you don't feel comfortable dismantling stuff, then be warned, if you fubar it it's your own doing.......
A little more info in your post (and the title) might elicit more advice..
sorry... the ring will not move at all its solid...it has worked prior 2 this happening
krusty, your PM inbox is full .
Unusual that. I assume it wasn't turned for quite a while?
TBH, it shouldn't really have seized that badly. Not much heat at that point of the optics & the plastic used is heat tolerant/resistant - a modern type of "bakelite".
Only advice I can offer is to check it's not physically jammed - perhaps has become cross threaded. Shouldn't really happen though unless it's taken a knock.
Try moving it when the PJ is hot & again when cold. A drop of lubricant could help (shouldn't be necessary). Be VERY careful though as if it gets in between the lenses/optics, you'll find it near impossible to remove.
As theritz has said, don't "fubar" it unless you're feeling flush & fancy a new Z3/HS51 etc...
Another option, albeit an expensive one is your local Sony or independent service center.
I'll let you know if I unearth anything else that may be of use.
Best of luck with it.
