Voltage checking and caps inspection will be the first thing to do.
If you can post the pictures, that will help a lot. Look at the inverter board to see if you are getting 12~18vdc feeding it, also look for caps with leaking/bulging top.

Select menu and choose the input you want or use the remote and push the input button to select whatever input you have connected to the TV.

Your power supply is faulty I'm afraid. Unless you have soldering skills, I am afraid you will need to contact a professional TV repair person. If you feel confident to try the repair, contact me with the model number, and I will let you know what components you need to change

If you are using the channel up and down buttons, sometimes it will skip channels. Try manually putting in 03 using the remote to change to channel 3. Also make sure that in the TV menu you have the TV set to Cable instead of Antenna.

That sounds like a text box. Press the cc button and keep pressing it. You will see different closed captions options on your screen each time you press the button. Finally when it says cc off stop pressing the button and you should no longer get the black box. If you have a cable box connected you may also have to disable the captioning on it.

Good day!!!!Commonly that trouble is cause of faulty capacitors on power supply board...Please follow this step on how to fix that problem on your own..

1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter..

I hope this solution will be helpful...Thanks for using fixya...

Hi
Im afraid that the only way is to buy another one is on EBAY.

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?)

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 at tv-part.com but supplies are limited. 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.
