Check the wall source plug and see if you have power there.
If yes,Then it may have a blown fuse in the power supply.

SOURCE: TV will not power on

There is not an internal reset for this. You would need to check what voltages you are getting from the secondary side of the power supply, this would then indicate if the problem is with the main board not starting up the system or if the power supply has a fault. If you have a multimeter then you can carefully check for 24v 5v & 12v supplies. If you are not getting any voltages then the primary side of the power supply may be at fault. The first thing to check would be the fuse at the incoming mains supply on the power board, if this has blown then suspect one of the senmi-conductors & check to see if any of the capacitors are swoolen if so replace them.

No power


unplug the unit for 24 hours and try it again. if the unit doesnt come on at all, even after that, then the internal fuse is blown, or a power spike / surge has friend part of the internal power supply. you'll have the go through the warranty process of the manufacturer, or find a local tv repair shop.

HP L2000 Sudden shutdown wont power up power supply good


what makes you think the ac park is ok
19vdc measured with a voltmeter proves this , only.
a 2005 (as old as) Laptop
its not new, things this old do fail.
Laptops are like dog years.. 7:1. so yours is 84years old
to fix a desktop is super easy
to test a laptop takes greater skills, the take down. is tricky
we take out the battery,
the the pack just make the fan run in the PC
does it>? if not the pack is bad.
or the MOBO regs are shut down. (shorts on any thing inside
some times the 19vdc is ok, at that pack
then 1 inches inside the PC its dead due to that silly power jack loves to fail. but not taking the thing down and testing that
its all just a guessing game...
the only insight there is on electronics, is power first.
no power, no joy.
test the power feeds first.

Dead tv


Sounds like a power supply problem. I am sure that the pop is the fuse blown. If the fuse is blown, this means that there is a short somewhere. Rear projection TV are like LCD projectors. And all of them use Switch mode power supply. If you are lucky, there is a chance that a protection device (like a varistor) is sorted. This means that removing this, even without replacing will bring your TV to life, however... Most probably the power supply is defective.
