The vertical ic of my jvc tv model no. av f21mx5 are always burn even i replace a new one

Just check the supply voltage input to the vertical IC. If it is more than normal, this type of fault can occur. Just compare this voltage . The TV schematic will help you to find this detail. Check whether the IC is firmly screwed on to its metal heat sink.

Why all power windows stop working at same time honda accord 2002

The most likely reason is a blown or loose fuse. Hondas also use a special controller on the driver's window control panel, and these controllers are notorious for burning out. As always, after confirming that the fuse is good, the best way to start is to get out your volt meter or test light and make sure you have voltage at the window control panel. From there, you trace back to find a broken wire between the door and the fuse panel or trace forward through the switch.

Does not power up at all no lights,

Try to check the fuse if not busted, the fuse is located at the main ac supply of your tv try t0 follow the ac cord and it will direct you to the power supply of your tv, it has two lines try to check or trace both lines to locate the fuse, if the fuse is only busted no burn marks try to replace with the same rating but if the fuse glass is covered with black that looks like something is burned inside dont replace it the other parts of your tv has a damage specially the regulator and the rectifier is shorted. Note before removing the back cover of your tv you should be sure that you unplug it first cause one mistake could cause serious injury. Good day and be careful.

check input circuit. trace bridge rectifier circuit.. make sure its good.. check tranformer or line filter.

Fuse is probably burning as a precaution because there is a problem in the input section.. either ac side or after bridge

I have a JVC tv only 1 year old and the picture is getting dark.

Sorry to tell you but JVC is a well-known un-reliable brand and if it's cheap, probably even worse. U may have screen burn from leaving a games console on while plugged into the tv, even if its not showing the game, it will burn it onto the screen. :(
