Discharge TV CRT (Picture Tube) - Descargar TV TRC (Tubo)

The issue with CRTs is that the glass dielectric, having been kept at many tens of kilovolts for years, will store charge deep in the glass, and this charge cannot be eliminated quickly.




El TRC (Tubo de Rayos Catodicos) de una TV o Monitor puede almacenar decenas de Kilovolts por eso que no es recomendables abrir una tv o monitor sin experiencia.



Lo que se ve es la "chispa" cuando uno descarga un TRC - no se alcanzaron a tocar los metaLes.

¿Are you sure who is the TRC?, may be is one capacitor.

[jimi57]

my tv is making a hissing noise like at the tube could it be it need deguassing or what.the noise is right at the connector wire part can anyone give me idea.i was a tech a long time ago.

[omgitsonlyme]

there are more sparks since the first contact?

[ChilenoCL]

The first contact if for discharge the TRC but isn't sufficient - the TRC is how a hug capacitator, and acumulate voltage, the discharge is for work safety - nada más

Discharging a CRT info would be useful to know.

I have to run a check up on my PC monitor. Do u ground one screwdriver to the boby of the tube and stick the other screwdriver in the high voltage cable Connector?

[ChilenoCL]

One wire go to inside the CRT, this wire is cover whit a plastic plug - be careful this plug have over 1.000v.

(UNPLUGED AT AC POWER) To discharge connect a wire at the chasis, i connect there to a screwdriver, is because the chasis is grounded and then i use the screwdriver and connect under the plug in the CRT and ready :)

Use a screwdriver because the plastic protect to you and the CRT discharge in the chasis and not in you.

hhahaha recorded from yahoo cam while showing to sum lolzzz

@ChilenoCL Wow man you must have been talking a lot of photos to make the slideshow this smooth.

glass does not store the charge directly the aquadad (black / grey external coating on tub funel) and anode plating inside the tube are what store / hold the charge, the glass (known as dielectric) keeps the 2 apart so the charge can remain, and not short out, basic capacitor 101.

good, i didn't see nothing, but good, good shit

Awesome video. Keep on with that good work!

[weeardguy]

To me, the spark seems a little small from a discharge without a resistor. I learned to use a fairly high resistor value for discharging a CRT (I have read about 1 M ohm )

[benjiexy]

i dont agree on this procedure..it may damage power ic's especially scr..this is the old days of discharging crt

una punta va a cualquier parte que haga "tierra" (la parte oscura de la pantalla o alguna parte metalica del monitor) la otra punta va debajo del "chupon" del flyback en el ganchito, luego haces que los dos desarmadores se toquen en su parte metalica correspondiente.

HAHA!
