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.

you have trouble in power supply it has a weak dc out put can you measure it using a tester.

Hi,

Friend this is a very common problem with LCD and also DLP within the power supply the capacitors

Start to fail and the way you can tell is to check them visually for swelling or expanding of the top.

It will be easy to see the bad caps will not be as flat on the top as the good ones, But also you can have a bad resistor or diode and even a bad regulator. Would like for you to take your meter and place it on DC voltage the positive end on every connector that says a voltage and the negative wire to the panel this is the best ground. Turn on and see if the unit tries to climb. If you don't find one that's trying to climb, another method is to locate a short circuit. Place meter on ohms or beep test follow same procedure no voltage should be shorted to ground. And this is the problem,

Exchange them and you will be ok, Well good luck friend. And if it doesn't work make sure the power supply is sending 24v to the inverters when you turn the set on your meter should climb but won't reach 24v because unit will shut down and if so we ruled out the inverters or back light I seen this problem also caused by the signal board it has a power on command missing and it looks like the power supply
is bad but actually it's the signal board, it may be labeled on the board a active high or low 5v which sends the command to the power supply


Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Hi,

It might be something really simply - you may have changed from Analogue TV mode to Digital TV mode or vice-versa.

Press the DTV/ATV button on your remote, which is just below the "MUTE" button in the top right-hand corner.

If that doesn't work, please let me know whether you are using a cable box, satellite receiver or whether your TV is just connected to an antenna and we can try some other options.

Regards,
BElectric

both tvs has has out of signal, check your cable or call cable operator
good luck

It probably just bad electrolytic caps that need replace on the power supply, if you remove the power supply and take it to a electronic tech, you can probably have the caps replace for less then 100.00.

it should be in your settings for what kind of signal the ant is to accept good place to start manuals can be hard to find hope this helps also try hooking another coaxial source to rule out faulty input

Have you tried different inputs on the tv? Does it happen with just that input or every input. It could very well be a problem with the video processor or input board on the tv. Did you try hooking up the same device to another tv and did you have any problems or did you just try the cables on a different tv? If you don't have the problem on a different input I would just not use the input your having trouble with.
thanks,
Lee

Requires surgery.
I have the fix.

Hi,
Fuse rating would be 3,15A 250V for this tv.
Hope this info will help you.
Thanks.

Try website like Remotes.com to buy an exact remote to the original remote.

Click here to find the power supply for you LCD. I would suggest to check the power supply part number from your LCD before ordering.

Some of the parts of it have loose contact that needs to be solder. Ask for a repairman to check and have it solder.

Check the power source?Yes,the power supply board is dead,that the board,where the power a/c cord plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.

Hi, I would like to help out.

Turn your TV back and on the left hand side look beneath the monitor. You will find the audio jack located beneath.

please click on this link http://www.hdtvsolutions.com/pdf/LTV-3201%20manual.pdf If you need the clear picture. on the tenth page you can see where exactly the headphone jack is located.

please let me know if you need more help. Thank you:) good luck
