Re: toshiba cf32c50 tv will not turn on
This is a typical condition if the power supply has failed or a power-consuming circuit the supply services has exceeded a predetermined current draw. The relay you hear is preventing further damage or even fire. You will need local tech help with this.

check circuit board for contamination. looks like white powder. if there is, clean with alcohol let dry. before plug set backin. if you can't fix you can use a stereo to get your sound thur.just hook up your cable box or what ever through the audio video jacks on box to audio in aux. jacks on the back of srereo
distorted sound sometimes accompanied by buzzing is caused by detuned circuit in the SIF amplifier and sound detector circuit. a distorted sound alone is caused by a breakdown in AF amplifier circuit so try to change the sound ic since its the only options left. good luck!
Electrolitic Capasitors in the power supply going or being bad will cause this. At some point a low value resister also will start to run hot or burn up. I believe it it a 16v 1500 uf cap near the relay. I would also replace any 10uf 160v caps in the powersupply too.
Hope this Helps,
Unplugged the unit the power outlet for about 60 sec.Then power it on again. If you have surge strip along the line. You should directly switch in on power outlet only. If this doesn't help.
As the relay is working you have power in standby mode. Check its supply voltages if its ok. Secondly you can check the the B+ supply it is in DC, If this is a crt type tv, check its horizontal output transistor, Check its flyback for short circuit. Capacitor near to it rated almost 800V, and deflection coil.
I would try a power drain: Unplug the TV's power cable so the TV is not grounded to the house. Then press and hold in the TV's own power button for one minute to drain the capacitors. Plug the TV back in and see what happens. If the TV will still not turn on, I would say you have a problem with the TV's mainboard as a dead power supply will not light any LED's for you.
you have damage your tv micro chip, regulator ,or horizontal output with static current when you plug out your tv from th plug,what is clicking is the relay trying to power up your tyv but due too the damage it cannot power have a tech repair your tv good luck
