Hi have a nice day!
Check if new fuse is of same type that is needed ie 2A , 2,5A as manual says. dont put different.
If you put correct fuse and blows then there is a short circuit at power supply area or after it and your TV must take to a qualified repair shop.
If you are familiar with electronic repairs write me down make and model to look for a service manual available.

if no any power indicator that light or even blinking, the first place to be check will be the power supply section you must check weather the fuse is blown.if the fuse is blown before you replaced with new one you need to check other component in the power supply section like transistor and diode. so this case need proper trouble shooting, if you think you don't have enough idea in any electronic repair just leave it to the trained tv technician.

Power went off will not turn on. When I replug tv in the red power light blinks for a monment then all power if gone. Is there an internal breaker? I was attempting to plug the jacks to my sterio through...

If the red light is blinking then the internal main fuse is good...sounds like the switchmode power supply regulator has gone may need to have a repairman look at it as it may be extensive due to power surge.

The TV will not turn on. I have verified that it has power and the fuse inside is good.

It is probably a horizontal transistor gone short circuit which controls the H.V. transformer no power for picture or the H.V. transformer gone short circuit as well or it maybe a power supply fault

Tv wont switch on

This could be a problem with the power supply. Yes there is a fuse on the power supply & if you have a multi-meter & are competent with electrical safety, you could test it. However, if it has blown then almost certainly something else will have caused it. You might have a short circuit bridge rectifier or faulty chopper transistor. If the fuse is ok, then you will need to check voltages from the power supply to find out what feeds you have. There may be a start resistor open circuit for example. If most of the start up voltages are ok, then you need to look at the line output stage & check if this circuit is getting any voltage supply.

Hi there!

Where you saw the Arcing, check closer to see wether the components are not loose on the board. You may only have to resolder the joints and problem solved. If the arcing takes place towards the tube, then you have a more serious fault. Thus involving High Tension, so I would not advise trying to repair that area if you are not familiar with TV repairs. Please unplug set before commencing any work. Regards and good luck, JUS004
