On any tv, first you must have two feeds coming in. That means either your tv must have two video cards, or your cable/antenna box must have two in order to se PIP. From there is a peace of cake... you push one button on your remote control and ....voila. Most tv's will have two video cards, one tor terrestrial antenna and one or more for cable/dish,.

I turned the 42HP95 TV off one night and it didn't come back on. Had the red LED flashing etc. Found the solution posted by CheapTech: http://www.fixya.com/support/t101749-tv_turned_itself_off_turn_back but didn't take it seriously because these things never work, others were mocking the answer blah blah. Well, just before kicking the damn thing to the curb, I grabbed a screwdriver, took off the back cover, unplugged the little do-hicky sugested in the Solution, and the idiot box came right back on. Go figure. Been working ever since. SO, you might want to try this before busting out the electrical schematics and dropping $$ on repair. Cheers.

Had the same problem myself. Took some doing but I managed to find a service bulletin that I downloaded. The problem is with the siene module and all you need to do is unplug connector JP63A from the main board and your TV will work again.
Take the back off the TV (there are a lot of screws) and look on the left hand side of the main circuit board that is mounted in the center of the TV. You will see a small white connector that is labelled JP63A, simply unplug it. Plug the TV back in and let it reboot. That's it, should be able to watch immediately.

The TV is on protect mode.
Try first leaving the TV power cord unplugged for some times, let say one hour or so.
Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.
If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.
The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.
1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.
2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.
If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.
If you are in situation 2 , then there is an internal fault.
Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.
Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.
If under warranty contact the manufacturer ringing the number on the user manual
If you want to repair at your own expenses, just locate any good qualified repairer.
