    tv dump questions part 1

    Hi everyone.
    I don't have too much experience on electronics.
    I'm a amateur.
    But is better if somebody give right answers to die trying

    1. Can I check a electrolyte capacitor (basic the main one) with the tv in on? and what voltages expect on standby mode and power on?
    2. When you check a transistor need to be the tv in on or off ?
    3. When you check you power board and make short between vs and ground, how many ohms need to be consider for detect if my board have a short.?
    4. how turn on power board on plasma tv with ps_on, standby, ground, vs_on?
    5. the 5v standby is generate after main capacitor?
    Thanks

    1=167 volt DC on main filter cap in standby,around 394volt DC when PSU is active(depends on make/model if there is voltage yes/no)
    2=TV needs to be off and unplugged
    3=mega ohms when healthy,better ask resistance between Vs/Va and GND on X and Y board
    4=Depends on make/model of TV,state your Tv brand and model(pictures a BIG plus)
    5=On most LCD TV's yes,on plasma depends on make/model(see #4)
