Activated by a PIN number, you can set Parental Controls on your TV and/or cable set-top box to control the programs that can be viewed on your TV. There are three ways to block programs:

• By Channel
• By Rating
• By Time Period (Not available in all areas.)

The V-Chip understands television program ratings and blocks programs based upon the rating level selected. All TV sets that are 13 inches or larger are required to incorporate the V-Chip technology. Parents set rating levels so that certain TV shows need a password to be viewed. For more information on the V-Chip and program ratings visit the FCC V-Chip site.
Several cable and satellite companies offer parental control options. They allow specific channels to be blocked so that they cannot be viewed.These companies also offer the ability to block shows based on language, violence, nudity, and rating levels. This offers more flexibility than the V-Chip.

Hope it helps ;-)

I had a similar problem with my 42 in Philips LCD HDTV.

Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of course) and found four bulged capacitors on the PSB. Many major electronics companies Philips/Magnavox, Sony, Panasonic, and others were sold capacitors that failed in 2-5 years instead of 10-20. The capacitors fail prematurely due to a lack of preservatives. Unfortunately, they were installed in all sorts of devices and cause a wide range of failure problems.

Here are some options for you.

1. Have it fixed by a professional $$$$$$$??????? (Is it under warranty?)

Remember, TVs CONTAIN HIGH VOLTAGE AND CAN KILL YOU! Do this at your own risk.

2. Open your TV and find PSB. (The board that the power cord plugs into) Check for faulty caps. If you find some (bulged or leaking) bad caps replace the entire board. The entire board costs around $250 right now because they are in high demand right now. They can be found online. I would definitely shop around though.

3. Remove and then replace individual faulty caps. This takes some soldering skill.

Caps are inexpensive and if you can take care of it yourself it will save you hundreds.

This may be your problem. If you determine that it might be.

I have a Tip/How TO tutorial on this site that may also help. It gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. Here is the Link: Fixing the Philips Turns/shuts off on its own problem. I'm working on uploading pictures to help guide people though the process as well. Let me know if I can do anything to help.

Hope this helps and if it does please rate it accordingly. Good luck.

had a very similar situation with my Phillips 42 in. LCD TV.

Here was my Problem. The Power Supply Board. I opened it up( Warranty was Expired) and found several faulty capacitors on the PSB. Its pretty common. Major Electronic companies were sold faulty capacitors that fail in 2-5 years instead of 10-20 due to a lack of preservatives. It wouldn't surprise me if you have the same problem. TV will work fine for a few years and then just fail completely or slowly deteriorate.

Here are the solutions
1. Have it Repaired
2. Check for faulty caps and if you find some(budged or leaking) you know you have located a problem
Remove the board and replace the whole thing.
3. If you have some soldering skills you can replace the faulty caps.
Caps are very inexpensive, under a dollar in most cases. I replaced 4 for about $5.00

Hope this Helps.
Good Luck

Try disconnecting unit from power source for several minutes. Before re-connecting power hold power button for 5 seconds and I hope this resolves your problem.

It does not require a remote and can be set up with the buttons on the front panel. This is a straight plug in unit and does not require any charging. If it is only staying on for a few minutes then it is most likely the power supply board over heating.

If you are looking for the operators manual, that can usually be down loaded from the manufacturers web site. If you are looking for a service manual, I use www.servicemanuals.net , You have to register and there is a fee involved for each manual you order, but you can download the service/schematic manuals for immediate use. They have an extensive library, but not everything.
