Well, I got a denon 2000f mkII very cheap and I assume both lasers
needs replacement. This unit are using the SHARP laser RCTRH8147 which

Also, hooking up a pair of "expendable" speakers, there is distortion
in the channel that measure dc voltage...and the other channel sounds

I noticed my 1992 KV27-XBR35 color quality had taken a decided turn
for the worse.  Turning down the color control all the way reveals an
image that appears bright blue/green in color.
It used to have a pretty good grey scale.

I have a vintage lathe that needs to have the cross slide
thrust bearing shimmed.  I'm not 100% certain, still need
to get more light on the subject and blow the hole out with
air, but I think the handle might be mounted with a blind

My cordless phone/charger uses a 9volt DC 200ma power converter, I was
wondering if I used a 9 volt DC 100ma power converter if there would be any
big safety hazard. being a 100 ma less, i was thinking would this only allow
my phones batteries to charge slower, or would the power ...

Keep in mind that I have schematic for this model.
Will not power up with PC connector plugged in (this is power for 40V,
-40V, 15V, -15V and few grounds) for the convergence board.  Like I

I am finding it not much worth it anymore
Unless its just dirty or object ( kids ) removal .

....And on top of that the remote is lost so I don't know how to access the
Serviceman codes without it.
TV was assembled Jan 2000. Cost over $350 and hasn't had a lot of use.
I hate to spend $45 on a new remote just to find out that there's more to it

I own a 20 y. o. GE TV, model #25PP5859K. [It was built in Nov. 1984.]
The original GE remote control <that came with this set> just broke.
I'd like to find some replacement but I'm concerned about the special
programming feature of the old remote. I figure that modern remotes

Found this set by the side of the road, it is stuck in the /demo mode,
is there a way to get it out of this mode?  I do not have the remote.

Strange problem, wonder if anyone knows what it could be.  I am in
Europe and have a Grundig television.  I get my local channels from an
antenna and also have a satellite system.  It seems that especially in
the winter for some reason, I get a vertically rolling screen when

I have an Electrohome Projection TV (Model: PROJ45) made by Mitsubishi
in Aug 1990. When you turn the TV on, it is asking for a Personal
Code. I don't know what the code is and the original remote no longer
works. Is there a way to clear this code. One site I found suggests
