why would anyone pay close to $125 to repair a set that can be bought
new for around $100 by the way rca and ge are now owned by the chinese
goverment and they are sticking the rca-ge names on even cheaper made
sets and flooding the market with them I saw a 27" rca flat screen at

just got a replacement mains filter for a dishwasher and am a little
confused as to the wiring. it is not a direct replacement for the one
already fitted. it has four tags two labelled L and N which are self
explanatory but the other two are both labelled U. Does the U mean

TPG 17" monitor Model TP785XE
No HV, led comes on, heater glows, HOT ok.
i tested the resistance from the flyback anode(big red wire) to chassi
and got a reading of 2.68M ohm.

I've seen a this type of problem in the circuit boards of other
Tektronix equipment, this time it's afflicting two of my DM44s.
The problem is semiconductive and resides within the glass composite
of the board itself. I have identified two 1-5 megOhm instances or

hi everyone. in about 6 months i'm going to relocate to Canada /BC.
i'm in a process of thinking to choose a new career as a

no specific informations on the net about this career in canada.i would

My xbox was damaged due to lightning.  It appears that one capacitor was
quite thoroughly fried.

Hi, it's me again, the guy who asked here about a vertical image
distortion and I fixed it with your help!
Now, that I gained a little confidence, I wonder if I should tackle
another issue I have in this TV set.

Does anybody have a good source for flybacks?
I need a TFB4132ed

I just purchased a Panasonic PV-27DF64 DVD/VHS combo TV. However, the
image is really distorted and I think I need to adjust the pincushion
on my set. Does anyone know how to enter the "service mode" on this
model?

I did some searching in the news groups but didnt quite find what I was
looking for.  I would like a project for me and my 10 year old son,
he's quite crafty with his K'nex and legos always making some weird
contraption along with the old pc parts and vcr's.  So I thought it

following your great advice my friends, I replaced the capacitor in the
vertical circuit (c455, near the IC LA78xx) and now the image distorion
at the top is gone. I ran the set for over an hour, it *seems* fine.
However, here is the puzzle: the TV set was off (unplugged and open ...

I have a 7-year-old 15" CRT monitor that is connected to a standard PC.
Lately I noticed that the size of the monitor's onscreen image is
affected by changes to the image's brightness (the brighter the wider).
For example, my Desktop background is dark. If I click to maximize a

I rescued an old Zenith SF2795W from the trash and the power supply was
making an audible whine noise. After swapping out most of the caps the
problem was cured and the supply was silent.
Now the other small issue is when text appears on the screen its a bit

It's probably a new defective generic flyback. I couldn't locate an HR
Diemen sub for this chassis. Parts replaced: FX3403, C3406, C3402,
QX3201, QX3208. QX3401 & flyback. Any suggestions are greatly
appreciated. I'll order a rebuilt chassis only if I have to because

I need an electrolytic capacitor, 100V/35uF. I don't have one right
now... can I use two in series, let's say 50V/68uF? The equivalent
capacity should be 34uF, and since they are in series, the maximum
voltage 100V.
