Question about Toshiba 57H84 57" Rear Projection HDTV-Ready Television
It was working perfectly, great picture and sound. One day, nothing, won't turn on, no visable damage, no smell or burnt spot or wire.
Please infrom on possible causesand parts needed.
This actually a very common problem with these televisions. If this continues to happen, the first thing you should try is a hard reset. Unplug the tv for about 6 hours. If this doesn't work you have an essential failure which will need repair. The two main causes of the type of problem you are having is either a poor solder connection , or the second a faulty power supply component. Either way it will need to be attended to by a technician if the reset fails. I recommend checking the warranty information that came with the unit if this continues to happen to see if there is any way you can recoup some or all of the cost of a repair which will be needed at that point. Hopefully the manufacturer will take care of it for you if it is within their timeframe.
If you wish to go for Service Manual that would help you to diagnose it in a better way, you could purchase the complete manual from :-
I don't think, 14 bucks is more than the value of the Television.
Let me know, if needed further assistance.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!

This kind of problem has something to do with the power supply board. But still, you need to check the following:
1. Convergence IC - $6.95
2. Power supply board - $76.99 up to $165.99
you may visit www.shopjimmy.com and type the component's name in the search field so that you could see the pictures.
You need to have a repair tech check which one is causing the problem and the service should costs $50 only for the technician.
Have a great day!
