Hi,
I'm assuming that your unit is dead seat.

Here are some DIY steps that may help you fixing the problem.

1. Check the power cord - check the cord it might be opened (no continuity).

2. Check the internal fuse - sometimes the fuse fail because of the power surge, replacing with new one will cure the problem, If this is the case I've advice you to use surge protector/AVR (Automatic Voltage Regulator). However if the fuse blew again this is an indication that you have a shorted parts on the power supply, you may visit the link http://www.fixya.com/support/r8053361-fuse_keeps_blowing for more info. If no reaction and still the unit didn't power up then you have an open parts on the power supply.

3.If you see that the fuse is intact on the board, don't attempt to touch anything because there some fatal components stored electricity enough to hurt you with a simple mistake only.

The next steps should be done by an expert or qualified technician because isolating the problem on the power supply is quite technical.

Also check if your unit is under warranty before opening the back panel, it will void the warranty. Avail it because the manufacturer of your unit will fix it for free or a little charge only.

Hope it may help you.

Thanks for using fixya.

Hello.
You probably did not have that tv plugged into a surge protector. When the power was restored, a surge came through the line. A power surge is a spike in voltage above the maximum a tv, appliance etc. can handle of 169 volts. They are very brief, usually lasting millinths of a second. Power surges can vary in duration and magnitude, varying from a few hundred volts to several thousand volts.

That said, now what do you do. If the tv is under 3 years old I recommend that you take it into a local TV repair shop for a free estimate of repair. If it is older than that, I would not repair, just replace. J.

Hello ma'am, you HP has power supply problems. this requires replacement of the board. If you have no idea, call for service.

Either someone is messing with you or the control processor is faulty.
Simple test: block the remote sensor in the front of the tv with a dark coloured tape. If you still have the same problem then the processor is faulty and the entire board will have to be replaced by the dealer (or an authorized repairman).

Clean the lenz if this doesnt solve it your Laser Pick Up assembly is bad have a Tech replace.
