I have toshiba TV 51H84, is not powering up the tv clicks but in wont come on. please help.
I have had my TV get into this state twice and both times it ended up being a blown transistor. Cost $300 each time to get fixed though shopping around for part numbers I think the transistor was only about $20.
Symptoms were a click sound when trying to power up but the power light would not go on and no picture or sound.

I have this same problem and replaced the entire convergence circuit board with the IC's included and the problem was not fixed. The convergence board costs $181. at Vance Baldwin electronics. I now have two and still have a tv that won't turn on.

I would not replace the convergence ic's just yet. first, pull off the CRT sockets off the picture tubes and lay them aside, making sure they are not touching anything. Next disconnect the Plugs off the convergence board, where the STK IC's are. Next see if the set will turn on now with sound. if it does, replace the convergence IC's. If it does not check the sweep power supply and or the main regulator IC and circuit. Good Luck Please do not forget to rate this thread.
