Look for cold solder joints in the power supply, more likely the 24vdc for the backlights is not working.

One possibility is the unit is thermally protected.
Does the TV have a built in fan? Check that all the vents are clear and the TV can "breathe".

Another is a bad solder joint on the inverter bard or power supply, heating can cause the connection to open and the TV to stop working.

I'd check the aerial connection.

This model TV is known for having power supply problems. The only way to be positive of the problem is to check the components to verify what is out of specs. Replacing parts that are not known to be defective can get expensive and may not result in a working TV. The safety circuitry is shutting the TV down when it detects a problem. Often this is caused by capacitors going bad. Looking for bulging and leaking capacitors and replacing any found can often result in a working TV.

Bad (bulging) capacitors on the power supply board. This is not your board but this is what the caps will look like when they are bad.

This could be either the Power supply or the Inverter transformers need replaced.

Westinghouse... | Answered on Dec 24, 2010


Hello Friend,
This issue seems to be due to over heating of power transistor in the power supply unit. Try replacing them. Also replace main big capacitors which could be leaky around that transistor . your issue should be resolved with this.

Thanks,
Shiva

The 720i is lower HD resolution and the 1080i is the max HD resolution.

Hello,
in this case i have to know if your tuner is working fine or not. First of all i like you to connect any external player Exp. DVD or blue-ray player if that works with audio then it is inverter board. if audio doesn't work then its main board. Also you will find out that if dvd is working fine on your tv than your tv setting is wrong or the tunes is dead. either way if tuner is gone then you have to change the main board. Either way let me know what went wrong i can provide you more information about what part need and where can you get it from.
Please let me know if you have any further questions or concerns. Also rate me if you like this post.
Thanks.

had a very similar situation with my Phillips 42 in. LCD TV.

Here was my Problem. The Power Supply Board. I opened it up( Warranty was Expired) and found several faulty capacitors on the PSB. Its pretty common. Major Electronic companies were sold faulty capacitors that fail in 2-5 years instead of 10-20 due to a lack of preservatives. It wouldn't surprise me if you have the same problem. TV will work fine for a few years and then just fail completely or slowly deteriorate.

Here are the solutions
1. Have it Repaired
2. Check for faulty caps and if you find some(budged or leaking) you know you have located a problem
Remove the board and replace the whole thing.
3. If you have some soldering skills you can replace the faulty caps.
Caps are very inexpensive, under a dollar in most cases. I replaced 4 for about $5.00

Hope this Helps.
Good Luck

Thanks for using fixya.com

What you just explained to me was the tv does come on but about 1 hour later.

This would put me into thinking you got a issue with the power supply.

Lets troubleshoot:

Do you got sound during this 1 hour power up? if so
Your having a issue with the lcd back-light and or inverter witch will need to be replaced.

IF not

You issue would be within the power supply itself. There could be a issue with a swollen Capacitor witch is not filling to allow the tv to be powered on fully, or other components within the power supply are failing.

Capacitor

Electrolytic Capacitors hold voltage. Due to age, power surges, and other weak components they can swell and cause long power up's, intermittent shut downs, and other issues with the tv.

You have to remember I am not there looking at the tv so I am just using your words and symptoms as causes and diagnosis. There can be other issues with the set.

Many videos have been posted on youtube.com on how LCD's have suffered from a Capacitor failure. By what you have told me so far it seems that a Capacitor "could" by your issue.

Warning Do not attempt to open or service a TV if you do not know what you are doing!

If your into do it yourself repair, I would recommend purchasing the part needed and with a little soldering skill you could have your tv working again. Here are some online stores that can help you get the part.

Best of Luck with your TV

First, look at the screen in darkened room to see if you can see any slight glow from the screen, if it does, then the problem can be the T-CON (not getting the 12vdc) or the main logic board not feeding the signals to the T-CON board.
if not, next place to check will be the power supply module, make sure it has 24vdc which is required by the backlight inverter to work, the reason for not having 24vdc can be from bad DC filter caps (leaking/bulging top, high ESR) or short circuits in the inverter board which will cause the 24vdc supply to go into shutdown mode, so you may have to disconnect the power cable that feed the inverter board to see if the 24vdc will work without the inverter board hookup, you will need to apply about 3~4 amp of load to the 24vdc to make sure it can handle that. There are fuses on the backlight inverter boards also. So there is some troubleshooting you will have to do to find out the causes of the problem you are having.

Look for cold solder joints on the power supply board:

You may have the wrong version of HDMI. If you have a HDMI V1.3 cord and playstation feature set, it will not work on a lower set. Your TV is most likely a 1.2 or lower version number and as such unfortunately will no accept V1.3.
But I would check the versions in your manuals first before taking this advice as gospel.
Hope this helps, please rate me if it does! :D
