    thanks I am pretty sure you are correct, I have some experience on electronics but after the hurricane ( Katrina) I have not done anything but try to regroup the other part of my life. I really really appreciate you getting back with me and you take care.

Hi the problem you are having is going to be one of the most common problems with that type of telly the problem is going to be the flyback transformer needs replacing and also the transistor neads replacing its the one located nearest to the flyback transformer and it will be on a heatsink.
If you are unsure what im telling you then you shouldnt risk the repair yourself as the telly has power stored in it even when its unlpugged it might not kill you but you will get a nasty shock as the voltage is amplified inside the telly so is greater than 240v so dont mess with it unless you are sure what you are doing.
If you are doing the repair yourself then you need to get the schematics so as you can get the test points that you can test using multimeter and osciloscope this telling you whats exactly wrong as a resistor or two could have blown when the transistor failed also the schematics will give you part numbers.
The transistor and any resistors are easy to replace but you nedd to protect the new ones from heat damage when soldering the new ones in you need to dispurse the heat using clips or something similar.
Now the difficult bit is unsoldering the flyback transformer this carrys high volts of electric and will give nasty shock if you dont dispurse the electric charge first you need to short across one of the caps to earth but you need to know the right one.
to remove flyback it regiures alot of unsoldering and resoldering possibly causing damage to the new one during soldering is easily done.
If you are going to get someone else to do the work like repair shop your looking at about £45 uk or $80 to $90 us so you need to think is it worth it let me know if you need further assistance ok

TV won't turn on


It sounds that, the memory IC to your TV has damaged. This IC can be located very near to main system control IC. A very small one, with 8 solder terminals. Even though it is very small, function of it while the TV works is great. The work is a semi-skilled one, and you must have some knowledge in electronics to proceed.

** TV won't turn on.** No picture or sound. Please Help !


If the red light won't come on it is not getting power.First,try plugging it in to a different outlet,or unplug one of the gadgets you know is working and plug the tv in there.You are simply switching.If you know that there is power coming from the outlet and it still won't come on then you'll have to check the cord;don't go much farther than that without expert help.

Toshiba TN55X81 Wont turn on but I hear clicking


Pull the three connectors to the yokes on the convergence board. If the set powers up, it's a good chance the STK392-110's need to be replaced. I fixed one today, and it has been running for 6 hours now.
