my son has a PS2, version 4, I think, (eight screws in the bottom). It
stopped loading and sometimes freezing, getting worse over a period of
weeks. I've done all the usual stuff - cleaning, increasing the magnet
strength, adjusting the angle of the laser (turning the little white

Are they still around?

I have an older (10-15 years) Magnavox 19" color TV that is serving me
well.  Recently, however, it has developed a sort of nervous tic.
Something within it is vibrating enough that it produces a noticeable
buzzing noise.  If I put a dictionary on top of it, the housing is

I have a Mitsubishi CS-35313, from around 95-97, don't remember.  I do
not have the original remote, not sure if that matters.
I have my audio out on the TV going to my receiver, but I get no
sound.  All my other peripherals work.  I just get nothing over the

The little PSU brick for my old Toshiba Satellite S300CDS laptop just
decided to keel over - no DC output whatsoever. (should output 15V)
Has anyone any experience of these and know of any common failures?
Checked the usual stuff - fuse is ok, bridge is ok, chopper transistor

I just bought a used Sharp 32" TV (32N-S350, made in 2000) from an
individual.  The image is very good, better than my new 32" Panasonic
which I'm going to return if I can solve a problem with the Sharp
on-screen display.

   A friend and I both bought the same model video on the same day.
It was the Panasonic NV-SD400
About three times a year one of them jams
and half the functions are lost until unplugged from the mains for about a

Mounted on the PCB of the Marantz model 2216, there are two lamps
soldered directly to the pcb.

info. I am trying again. this amp is missing TR1 and TR2. If anyone knows

Does anyone know the defaults codes in the service menu for a

I was wondering when checking a cap for ESR, how do you determine good
or bad? Do different type caps have different acceptable ESR limits?
Should all caps have infinite ESR? I am still a beginner in repair.
Also I am purchasing a sencore LC101 that will test for ESR. Any help

Traced intermittent shut down to bad coil in main power relay. Is there an
on-line lookup that'll give me the part number from the RY601 component
number? Relay has SPST NO contact rated for 15A @ 250VAC and 100VDC coil.
Thanks.

picture. is it a simple fix or something much worse? if simple how do

   My Mitsubishi has a series of black dots spaced at regular intervals
running diagonally across the screen and then repeating again on the
lower part. A tech that came out said it was burn-in and would not be
covered under my warranty. I've seen burn-in on TVs and monitors ...

Does anyone know of where I can find this manual.  I found a site that was
selling them for 75 USD, but I feel that is a little high. Ideally I'd like
to be able to D/L a pdf from the web.
Thanks!!!
