Re: laptop keeps turning off/restarting every 3 seconds,...
Please check if this laptop has an overheating problem. If it has an overheating problem, then please check the air inlet, outlet and fan (if fan does not spin, then you have to replace the fan). If it does not have an overheating problem, then you can test the laptop using another hard drive with a fresh operating system. If it still has a problem, then it means the motherboard is bad.

Try removing the battery and restart. Could be a bad memory module, fan not working, CPU going bad, graphics chip overheated and going bad. I assume it is out of warranty so you might have to take it to a repair shop.
Common procedure in resetting the password is by resetting the motherboard by reseating the CMOS battery. You need to access you motherbard and locate the circular silver metallic object on the motherboard. This is much bigger in size compared to a wristwatch battery. CAREFULLY remove the CMOS battery, avoid touching it with your fingers, and leave it out for about 120 seconds. This will flush the CMOS memory which stores the BIOS password and all other configuration. Put the the battery back in and turn on the computer.
Other procedure is the jumper reset. Some, but not all, motherboard manufacturers provide a set of three jumpers on their motherboards that provide you with the ability to clear the Bios/CMOS settings, thereby allowing them to be reset. For the most part this is used when the Bios/CMOS data becomes scrambled and you need to clear the Bios/CMOS in order to return the computer to a functional state. This same procedure, however, can be used to clear passwords from the Bios/CMOS setup. Typically a jumper will be found across pins #1 and #2 as the default position, and by shutting the computer down, unplugging the power cord and then moving the jumper so that it is across pins #2 and #3 will clear the Bios/CMOS settings.
If procedures above has been done and yet you are getting same results. Its time to call you manufacturer and have the motherboard re-flushed or re-imaged.
The 3-beep code (probably 1 long then 2 short beeps) means a memory problem. Take the RAM modules out of their sockets, gently clean off their contact fingers with a pencil eraser, and plug them back in. Make sure they're firmly seated and latch into place. Try restarting the computer.
If you still have the beep code, try to borrow a known good RAM module of the same type for testing. It doesn't need to be the same size (in MB), but close in speed. This will let you determine if the motherboard itself is bad.
If you don't have a known good module for testing and there's more than one module installed, take them out again. Reinstall one and try restarting the computer, and repeat for each module. This allows you to check each one separately to determine which is causing the problem. (This is where a good piece for testing is handy. I've been stung several times by all the memory being bad, and thinking it was the motherboard. Now I always keep some good memory for testing.)
Turn off the Notebook remve all the peripherials, Remove battery and disconnect AC Adapter and then press and hold down power button for thirty seconds. After 30 Seconds connect Battery and Power supply as soon as you tun on the Notebook keep on hitting F10 Notebook will show BIOS then F9 Notebook will show Load Set-up Default than Hit yes and Hit F10 again it will show save Exit and chnages now that show Fix the Problem

I would try leaving the TV unplugged for 30mins so the TV can reset itself.
If that doesn't work, your TV should still be under warranty. I know 95% of come with a 1 year warranty.
The most common problem with Sylvania TVs made by FUNAI, the Backlight Inverter board fails to early in life. ( That's the part that powers the screen)
The Tv can't power up the screen and it turns off automatically. Basically called "Protection Mode" so it protects the other parts inside the TV.
Try this and see if it fixes your problem...follow these steps. 1. Power off the unit. 2. HOLD down the power button and you will see "Pre Boot Mode" appear on the lower part of the display. KEEP HOLDING the power button down and the display will flicker, do this until the pre boot mode message disappears. This seems to take a long time (60 seconds at least). 3. Once the pre boot mode message disappears release the power button and your device will perform some activites to try recover from the problem.
