A new hobby for me; Gathering Information

[Yamiii]

Hello, My name is Travis. I've gotten an interest in repairing TV's and i can get a pretty good constant flow of "damaged" Tv's so i thought why not.

I have a few questions that would be great to be answered by this knowledgeable forum.

1) Can you guys point me in any direction to videos/guides to repairing TV's.
2) Interchangeable parts for TV's and how many parts can be swapped out and replaced by other parts
3) I've invested in a Multimeter any vids/tips on using it.

I just want to feel more comfortable around a TV and to get a better understanding

Would like to thank you guys for providing such great information and thanks for replying to someone who may seem a lost cause

For videos/guides i just use youtube there are some very good ones on tv repair also some very good ones regarding using a multi meter for boards that can be swapped out i use shopjimmy and see what they list as alternative boards that can be used in your tv but they have banned uk ip address so you need too use something like anonymox to view there web pages they also have some good pictures you can really zoom into so you can sometimes check parts/trace etc on the boards.

Once you get past the bulged caps videos. I would highly recommend norcal715 on youtube. Most important first step HOT side of power supply is most dangerous part of tv. Use care when making measurments. Also your ground point for measuring is different than the rest of the circuit. Also uk guys might want to know were you get your tv's

Never understood that. Why exactly?

A few posts from the guys in the UK say they have hard time picking up broken tv's

That's completely fine , I try to be very careful when entering a TV i stay away from metals when plugged in and when testing i try to ground myself with the main metal on the board.

Some decent text book advice when using a multimeter to check voltages:-

Voltage measurement is perhaps the most common function a multimeter is used for. It is certainly the primary measurement taken for safety purposes , and it should be well understood by the operator of the meter. Being that voltage is always relative between two points, the meter must be firmly connected to two points in a circuit before it will provide a reliable measurement. That usually means both probes must be grasped by the user’s hands and held against the proper contact points of a voltage source or circuit while measuring.

Because a hand-to-hand shock current path is the most dangerous, holding the meter probes on two points in a high-voltage circuit in this manner is always a potential hazard. If the protective insulation on the probes is worn or cracked, it is possible for the user’s fingers to come into contact with the probe conductors during the time of test, causing a bad shock to occur. If it is possible to use only one hand to grasp the probes, that is a safer option. Sometimes it is possible to “latch” one probe tip (onto the circuit test point so that it can be let go of and the other probe set in place, using only one hand. Special probe tip accessories such as spring clips can be attached to help facilitate this.

Thanks for the info from now on i'll try to latch the negative to something rather than holding. Is there anywhere specific you can point me if not i'll continue to browse
