Doesn't power on_Blown fuse (F601) T4AH250V

Replaced fuse and TV still doesn't powers on and anything.

Checked power board (1AA4B10N1630A) for shorts i.e. {open resistors or shorted diodes or transistor} Nothing visibly seen that would indicate a problem. AC voltage (120 v) to power board also have 5v Dc for standby power voltage

Yes, the power tested ok coming from the power supply and I unplugged each board individually to see if it was one of those. Each one I unplugged made the picture worse or go away so I know they work and they tested correctly. I'm wondering if I did something replacing capacitors or if I may be shorted something. It turns on and off fine, I have sound and picture but just like I said fuzzy and dark and mis colored

My LG Flatron rear projection TV won't turn on. The on/off power button is not turning the TV on. There is no click sound and the red light doesn't come on. The TV is connected to mains power and ther


tried with other ac outlet doesn't work?. if still won't turn on, at this time you will need to remove the rear cover to gain access the internal part. since your tv doesn't have any power indicator, the first place to be checked will be the power supply board this is where the power connector cord is connected. now look for a blown fuse replaced with the same rating. but take note before you replaced the bad fuse you must need to have component testing in the power supply board which the cause of blown of the fuse. like shorted bridge diode, open resistance and defective mosfet or bad regulator ic.at this time you will need a device called digital tester to check weather the parts need replacement.hope this can help good luck.

The TV won't turn on. The little light by the power button doesn't even come on


Blown fuse caused by a shorted power supply. Relacing the power supply board should solve the issue in most cases. You can get a power supply board from www.tvrepairworld.com

Toshiba 57H83 will not come on, not lights and doesn't make any noise when you hit the power


Open the tV, and locate the fuse. There will be a glass cartridge type fuse, on the main power regulator board. Look it for blown up. If it has blown up, never replace an other in place, until the reaosn for blowing up the preset fuse has been checked and cleared. If you do so, it might make so many other componets to get damaged. If you are not handy dithe internal circuits of TVs', it will be best to contact any expereinced service technican locally.

I have a Legend 42"


In that board, check the chip under the big heatsink.
Find the replacement and change it. Put a new fuse and that's it.
