Hello, i just saw your post.. i know this reply is so late, and you might have probably found a solution. But i will still give you some guides to help you figure this out.

(1) First and foremost, make sure your connections are set up properly (exactly as in the manual). most HDTV'S require a DIGITAL OPTICAL CABLE to be connected from TV to receiver. Read the manual on your TV and see the required wires for external audio

(2) go to your TV audio settings. Get to the speaker option, and turn it off ( this assumes your expensive TV is an HDTV). By turning it off, you signify that you want the sound option to come only from the speakers.

Hope it helps

This can be tricky in this set I have replaced ps, logic , sdr u and d, and I think my problem was Logic board at first. There were lights on this board that goes back and forth like the Kit car, this tells what is not working. This can be very expensive in the shop. But it's complicated also.

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.

The relay goes off because the safety system in the power source detects an overload and shuts the source down to protect it. On a tv this old the first signs of old age begin to appear. Open the tv and look for failed capacitors on the power source and the Y-sus boards, then check the voltages.
Replacement boards can be found here

if the tv is completely dead, your first step is to check the fuses in the power supply.but if you get the standby light, and nothing happens when you hit the power button, you need to call the repairman


good luck

I don't know how integrated the driver circuitry is with the display but the screen is addressed like a matrix (XY) and some of the drive circuits for those areas have died. This could be an expensive problem; I hope you have some remaining or and extended warranty.

a surge occured. now no power is present. not a flick of juice when main switch is pressed.

The vertical line, in my case, was due to a bad contact on the flexible printed circuit. I fixed the problem by using a piece of a rubber eraser to apply downward pressure on the flexible circuit as shown in the picture. To locate the faulty section lightly push on the flexible circuit from lef to right untill the line dissapears.
