Hi
It's a power supply problem board in the TV. It's a bad capacitor or two on the Power supply board. It is suggested to replace the four (apparently inadequate) 1000uF/16 volt power supply capacitors in the "DM module" (one of the two onboard microprocessors). These capacitors are apparently undersized, in that they will eventually fail when there are voltage fluctuations in the circuit above 16 volts. It is recommended to install either 1000uF/25 volt or 1000uF/35 volt capacitors as replacements, so that they will be more than ample to handle any voltage spikes that will occur. Buy the (4) 1000uF/35 volt capacitors as replacements and take the back of the TV apart and remove the faulty DM module, then get the DM module's printed circuit board and re-solder the old capacitors and install the new ones. If you are not technically skilled enough it is suggested to seek help from a technician.
Also try unplugging the unit for 24 hrs and plug it back again.
Please get back to us if you have further query else please accept the suggestion.
Thank you for contacting fixya.com
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.
Many electronics companies 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 $$$$$$$???????
2. Open your TV and find PSB. Check
for faulty caps. If you find some (bulged
or leaking) bad caps replace the entire board. The entire board costs around $100
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.
I have a tip/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. It's called: 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, so if you would like to view them check it again soon. Let me know if I can do anything
to help.
Hope this helps and Good luck.

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.

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