eric foster: So if the anode of the picture tube is charged with HV wouldn't the pins on
the flyback be charged too? In other words it would be prudent to
discharge the pic tube and any large capacitors before doing anything else
on the set.
ColumbiaTerrace84: Hello, I wonder if you could please help. I have an old CRT TV which works
fine EXCEPT when you turn it on the brightness and the color goes up and
down erractically. It might be just the knobs on the front need cleaning.
Do you have a video which explains how to fix this problem? Would love to
hear from you or anyone else who knows how to solve this problem. Thank you
unlokia: Just a point - you USE a technique, you don't "do a technique". Grammar
point. Thanks for video.
Amra: You commented below, in all caps, that these videos are for people who
already know what they are doing... if they knew what they were doing, why
would they be watching a 'repair 101' video? Then, you spend almost the
entire first three minutes explaining how to check a fuse and then you have
a tendency to use the wrong terminology (diode checker instead of
continuity checker, volts of power, etc etc). I have difficulty believing
these videos are made for people who already know what they are doing...

Ray Haynes: I know meth addicts that tweak on their tv, Do you recommend this?
MultiTechnicss: Annoying voice and a bad way to discharge a CRT!.... sorry
ThePAracer: Volts don't hurts you. AMPS do
FaZeFrost: is there a way to replace parts like the glass screen and the rca cable
inputs and anything else to make the picture quality look new?
FaZeFrost: this is cool (:
John Forzuelo: what digital tester did you use sir?
StuntyMe: my d2102 transistor and resistor for power supply is blown but my fuse is
intact what is the cause. what should i check?
chrisstv1979: @TrueBlueAustralian Then you will see fireworks! I knew someone who used a
twisty tie and they blew out the entire power supply. I recommend not using
foil as further damage will result. These tips must remain serious and
proper safety devices used to prvent shock or fire hazzard. Safety is no
camlpg: I have a 2002 Akai CRT TV CTS2550 and there are red blue green horizontal
lines on one section of the screen. Above the R-B-G distortion white
horizontal lines appear periodically. I visually checked the chassis of TV
and there is one capacitor that is bulged. It is the largest cap on the TV
and the only cap with a rubber top casing. Do you think that the single
largest cap is defective or are there other caps or components that could

trying to teach it.
GLaDOS488: my tv will burn out if i play my tapes on it

MrHammadmossop1988: I don't know if anybody can help me but quite a few years ago in 2010 my
uncles television which was a sony profeel sadly stopped functioning
correctly I pushed the power switch in and it completed the circuit and the
green pilot lamp lit up on the television however after 8 seconds or more
the TV didn't start up and I noticed the TV was dead but I don't know what
could have happened in order for the television to stop functioning
correctly I don't know if one of the components in the TV failed
chrisstv1979: for sure replace that one. Then recheck to see if it works. If so you are
done, if not, check all caps with a cap checker if you have one and replace
any that appear bad
devilmecare: I have a Toshiba 27AF44 replaced 2 caps. Picture rolls up halfway with a
black line 2 inches wide horizontal across the screen mostly does it on
commercials. Any ideas to fix it?
Enemorio: 0 ohm means continuty. Infinite ohms is open circuit. You can deduce the
latter from Ohm's law V=IR.
chrisstv1979: I need a brand, model and year of the TV. It sounds like bad caps in the
horizontal section and the CRT might be weak. Please upload a video of the
TV if you can, I can better assist you.
apdd2003: I have akai CRT color TV.. it power on starts with compressed screen with

annoying!! any tips to solve the problem. 2) how to discharge EHT section
before starting any repair?? i have read that it can store few KVs even
andre palmer: how test a tv yoke
BugsWisely: Ohms show continuity. 0 ohms = no continuity. A fuse is not a diode.
electricity can flow either way thru a fuse.

Wilma Williams: I have A 50" panasonic projection HD TV that is not working any moore. At
first when I would turn it on the power button would just blink. I'd have
to unplug and plug it up a few times before it would come on. As time went
on this problem got worse and so did the color quility of the picture
colors bleeding and out of focus. Please tell me what could be the
problem,it is an older TV so if it's going to be expensive I'd rather not
even try to fix it.
133MHzz: Some things I'd like to add, a severely trapezium shaped picture can also
be a sign of a bad deflection yoke, and as you said if you replace the yoke
on a CRT it might be impossible to get the convergence right. Also, I don't
particularly endorse your method of discharging the CRT using the neutral
on the plug, mainly because relatively modern CRTs (mid 90s) have an
isolated chassis, thus no connection between CRT ground and AC ground.
Older TVs and non-US TVs might not have a polarized plug.
John Liddle: Tv go down with titanic or what ??
IzzyGamer: Magnavox 32', got it some time in 2000, when the tubes were being pushed
out and the flat hd's coming in. My problem is the screen turns off, and so
goes the sound also, but the light that indicates the tv being on, is still
on. So I have to hit the power button to turn it off then turn it back on,
it works for a little bit then off it goes again. Any idea that might be
why it does this?
devilmecare: Thanks so much. Your videos help slot.
ChiTownWrx420: @Miketar2424 hannobisschoff1 is 100% correct. morons
Aldrin Marquez: thats great! I've learned alot about your finger...
devilmecare: I meant a lot.
whiskeyify: I have never seen any tech discharge a picture tube like that...and I don't
recommend you do because you might damage something. Just slip a
screwdriver under the cap and then use a wire cord with clips on each end
and touch one end to the screwdriver and the other end to the silver ground
strap on the pic tube. In the old days we would discharge the tube to the
metal chassis of the tv, but that was back in the 1960's when we had tube
sets. I'm 61 years old and have been doing this for awhile.
