Hi,

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!

    I searched for the exact part number of the convergence IC and power supply board for your Toshiba 57H84 but I can't find it anywhere.

    I'm sorry, but the best thing to find it is by checking the components itself.

    Thank you!

Samsung flatscreen tv model LN46C600F3FXZX has sound but no picture


Video section has become compromised and no longer functional. Audio being separate from the Video may work perfectly, but the Video portion sustained damage to the circuit board or the inline safety diode blew. If any parts of the Circuit Board fail, you need to replace the mainboard. The cost to generally fix a circuit board is usually more than the replacement cost for a new unit. Check all fuses or circuit limiters inside the TV and if there are no shorts, burned parts, or obvious smells on the mainboard, transient current may have trickled in and damaged sensitive electronics. Have a professional Technician do tests to locate the source of the problem.

Sounds like a cold solder joint, turn the main pcb over and see if you find any cracked solder or where the solder looks like it got hot.
