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.

How do i turn off the closed caption on my toshiba 51h84 tv? i tried setting via the remote and changed the CC option to OFF but i still see the closed caption wording...it is driving me crazy!! help!
What is the source of your TV signal: Cable? Dish Networks? DirectTV? Antenna?
Many times the Cable/Dish Networks/DirectTV controller also has an option for closed captioning. Please verify that a controller is not setup to deliver the CC data.
Also, try setting the TV CC using 'C1' or 'T1' and selecting 'Enter' to accept the change; then come back and set CC to 'Off' again to see if toggling on/off helps.

It is your projector tub if you are getting alot of blue in the picture. Those guns are very expensive to replace. I am sorry to tell you that. It would be cheaper set from wal-mart for your kids to play on.

Help! Toshiba 51H84..Power light flashing, tv picture won't come on!
First thing that needs to be checked is the convergence IC's. Those IC's are located in the signal board and are really hard to remove. You need an experience technician to fix it for you :)
