The problem is that there is no sound at all. the LED power light lights up, so there's definitely power, but somewhere between the power and the speaker, there's a problem. any suggestions? the capacitor gets real hot, but i thought that was always the case??

Back light led driver or the led array is faulty. check and confirm the voltage to the led back light from the power supply. normally 35V to 100V according to the brand and model of the tv. Check the voltage if the voltage is somewhere around the above mentioned voltage the then the tv have problem with the led array behind the screen . If the voltage is missing then the led driver is faulty. Normally the led drivers is found integrated to the power supply board. If so then you have to replace the power supply board as a whole. www.electro-medical.blogspot.com
Could have been a power surge. There should be a reset button on the tv somewhere. You did not mention model number. Look in your manual and troubleshooting section. Look for info to reset. As well, you should definitely add a surge protector to the mix. That is between your electric outlet and the tv plug in
never seen one but if you look really hard im sure you will find the plug in it is most likley close to the power inlet these lights run off dc power converted from ac power there is a driver somewhere that has the plug in
It sounds like you definitely have a short. Get an ohm meter and probe the power wire to each light. One of them should register continuity to ground. This will give you a starting point for where to start looking at the harness.
Now,u plug in the tv u get a solid red standby power red LED light in the front of the LCD panel right?When u push the power button on the remote u hear a clicking sound?Only one clicking sound,not the power supply board problems.It the Tuner board problems.But u can make sure it the power board problems or not.By taking the tv aparts check the power board,that board where the a/c power cord goes into it.Look all around the power supply board check for these leakage capacitors,they alway bulges up it top or puff up it top.No bad leakage capacitors,then it not the power supply board problems.
You may have a faulty adapter. Check the connector with a multi-meter, the voltage reading should be slightly higher than the voltage that is printed on the label on the back og the power adapter.
If the light on the power adapter does not light up when you plug it into the mains, then it is definitely faulty and you need a new one.
When The Light Is Blue You are getting Power To The Unit. Have You Tried removing the battery Leave The Power Cord Pluged Into The Side Of The Unit. Then Try To Power The Unit Up Again. If Nothing Happens. Chck The manual I Think There Is A Reset Button Somewhere On The Machine Most Toshibas Have Them Somewhere. Hope This Works
