I have had my TV-- a 42" Philips plasma-- for

Put new batterys in the remote,

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.

make sure the menu button on the tv is not stickng

This fix was posted on similar problem, worthy of repeating: Replaced 3300mf 10V capacitors at PS. Both had bulged slightly. Upsized to 25V as the previous solution poster had suggested 16V but I could not locate 16V so used 25V and TV is back to normal!

Philips.com should have a software upgrade for your TV to fix the problem. This is a common problem with Philips TVs and they have made upgrade software to address the problem.
Go to the Philips web site and all the procedures for download to your TV will be there. The only thing you will need to this is a USB memory stick. Download should be FREE.

you need to replace y-sustain board.

I have phillips 42" plasma tv it has 7 red light flashes at start up and locks out

You can go into the menu and adjust the picture setting. If that does not fix the iss and the set is under a year old then it will still be in warranty. Contact Philips at 1-88- 744-5477 and have them do the repairs under warranty. Don't do it your self because that will void your warranty.

if the set is less then a year old it may be under factory warranty.
it sounds like the vscan, vset , or vsus voltages are off..it could also be the panel itself..contact philips
