Did this video help you?

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

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?

John Forzuelo: what digital tester did you use sir? 

FaZeFrost: this is cool (:

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 JOKE!!!!!

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 be defective?

OneCoolDude08: 13,000 volts of power? No watts is power. Learn basic electronics before trying to teach it.

GLaDOS488: my tv will burn out if i play my tapes on it

extended004: i have a same problem but i hear the sound but no image just one vertical or horizontal line. I found that crt have an some coil that is bad solider and the burn wire.ill cut that wire and solider that coil on his place and turn tv on and i works :D

chrisstv1979: SAFETY IS MY NUMBER 1 PRIORTY AND NOT TO BE TAKEN LIGHTLY. PLEASE DO NOT COMMENT ABOUT BY-PASSING SAFETY. IF YOU DO, YOUR COMMENT WILL BE REMOVED. THESE VIDEOS ARE NOT FOR ENTERTAINMENT, THEY ARE FOR EDUCATIONAL PURPOSES AND ARE INTENDED FOR SOMEONE WHO KNOWS WHAT THEY ARE DOING!

rotesil: do you repair arcade monitor?

MrHammadmossop1988: Well Chris you have really helped me thanks for this

gungonjayson: How about may goldstar 21" crt tv....the voice on channels are clear and ok,but the display are no picture shown only but black and white lines....

TheCRTman: Thanks for the tips!

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

hannobisschoff1: @chrisstv1979

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 black bars at top and bottom.. after 5 mins or so it is normal on bottom but top portion is still compressed with faces looking funny..actually very 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 when OFF

andre palmer: how test a tv yoke

CrackKillzWeedHealz: I have a tv that was struck by lightning. What would that more then likely affect on the tv? I've tested the power supply area and everything seems to be working there. Please help If you can

BugsWisely: Ohms show continuity. 0 ohms = no continuity. A fuse is not a diode. electricity can flow either way thru a fuse.

icec64: I got a Crt, T.v set and the colour is screwed. It uses blue to display the colour black. It also got some horizontal line running across it, this is not seen when the display is showing a picture. What do you think is the issue?

Miketar2424: @hannobisschoff1 stop being an assburger

Jerome Cabral: I have had 26 years of vaccum tube/soilid state tvs.this is very intersting

jhorix oraiz: hi what is posible problem of my samsung CRT tv.no power at all totally dead.i check already fuse its working.

cecilia frederick: hello i have a 20inch daewoo tv and while watchin a tv show the television went off and has not come on ever since not even the standby light is on, but i keep hearin a ticking sound coming from inside the tv

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.

TrueBlueAustralian: if the fuse is blown use foil.!!!

icec64: thank you for the reply

Jusitn ha: u fail

chrisstv1979: @hannobisschoff1 Lets get this straight: I am a technician of over 12 years and know my tech terms. It is a volt meter or a multimeter, so both terms are correct. And as far as diode check, its diode check. When you put the meter in diode check it shows the diode symbol on the display. Do not knock my videos or knowledge please or I will block you from leaving comments.

chrisstv1979: no it can remain in circuit for testing. Remember approperate comments only. Do not ever call me an idiot or you will be not able to leave comments on my channel.

Josh1001w: dude the only way to be sure that the transistor is good is to take it out then check it because sometimes it is parallel with an inductor or transformer that would make it appear bad

whiskeyify: @chrisstv1979 using the diode check is a quick & easy way to test fuses and those large white resistors. I find those large wattage resistors usually go open. This is the way I do it when I'm on a housecall it saves you time. Good. video.

dhanedhar: hello i got a lg CRT monitor when i switch on the computer it does not work i want to repair it i have got a soldering gun,soldering wire also i would like to request you to keep the camera in such a place that the whole circuit board and the process of repairing and in which part is to be repaired is visible thanks for such tutorials
