Model p2510r-w101 25" philco serial#21944625 started with intermitant shut down problem (tv would flash like it trying to shut off but would delay approx. 10 seconds until actual shut down)today when I turned the tv on the horizontal control was gone and it refused to powerdown even manually pressing the power button. unplugged it from the wall, I let the unit sit for a few minutes and tried to power it up but it now refuses to power up either remotely or manually.

you have the same problem I have. The problem is fixed by changing the new light bulb. The problem appears again after 1500 hours of use. You can keep buying new light bulbs or avoid it by not buying another Samsung TV.

I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
Thanks to those who posted the solutions

You most likely have some faulty capacitors on the power module. You can easily identify a bust capacitor. They will have swollen tops. Here is a sample pic:

Check the specifications of the faulty capacitors, and getthe replacements from your local electronics shop. If you are comfortable withthis, you can use a pair of needle nose pliers to G-E-N-T-L-Y pull out thedefunct capacitors. Once that is done, solder in the new capacitors carefully. Ifare unsure how to do this, try to get a friend who knows this kinda stuff to doit for you, or get a qualified technician.
Warning: If you do not have a background inelectronics repair, or are inexperienced, get a qualified technician to do itfor you.

REMEMBER there are very dangerous voltages inside a TVthat can KILL. Be sure to work SAFE when dealing with electricity. DISCONNECTTHE POWER BEFORE YOU DO ANYTHING.

If you want to go in for a long term solution, youcan easily replace the whole power board. You can get spare from HERE.
