Hi,
Please reply couple of questions about TV to guess what could be wrong.

1- How many times standby light blinks, there would be interval of 3 seconds in blinks so count pause to pause.

2- Please intimate exact model of TV, written on sticker pasted at back of TV. That will help me to check its schematics.

Thanks.

How many times do this standby LED blinks at one time switch on? These blinks are fault indications. From the number of these blinks, you can get an idea about the faulty section circuit inside. Count it. If you wish to get more details, check this site. Pull up older posts there. Check this site with patience, as it has over 2200 posts now.

Over-voltage protection circuit energises. Check the output voltage tht comes out of its SMPS section to main board. If this voltage is more than/less than normal, this kind of fault can occur.

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. 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. Let me know if I can do anything to help.

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