There's a good chance you have failing electrolytic capacitors either in the power section or the inverter section or both.
Any caps in these sections that look bulged at the top, or bulged/leaking at the bottom (look for discoloration of the circuit board around the base of the capacitor) need to be replaced.
If you repeatedly turn it off and on, eventually it'll probably stay on, but every time you turn it off, the unit will get harder and harder to start up until one day it just won't.
Sometimes you have to do the opposite to start it up and unplug it for some time and then try again.

If you aren't tech savvy, don't worry, read the rest of this solution and watch the videos.

If you are handy with a soldering iron and can identify the power supply and/or inverter / FM section for the backlights, an inexpensive handful of capacitors will likely fix you right up.
Match the capacitance on the capacitors. Go over voltage if you can, and still have them fit.
IE - it's not a bad idea to replace a 10V cap with a 16V or 25V or even a 50V, but don't replace a 680uF cap with a 500uF or a 1000uF (unless you are SURE it's only doing supply output ripple filtering,
and even then, you should go OVER, not under the uF rating).

Most of the caps that go are 10V 1000uF or 3300uF.

I found some great videos of the procedure (for many Samsungs with the same issue) on youtube.

As you can see, this issue spans plasma TVs, as well as large and small LCD TVs and monitors, amplifiers, computer power supplies and motherboards, and other electronic equipment.
The parts are cheap, and skill required is minimal.
A great parts source is Digi-Key, and you can order the parts online at www.digikey.com
They typically cost under a dollar a piece plus a flat shipping rate.
The parts usually arrive one business day later.
If you watch the third video, you will see that even someone with no soldering experience can perform these repairs as demonstrated by the woman in the video.

The tv remote that came with the tv unit.The tv remote might have channels buttons up/down buttons functions and numbers pads might be shorted and dead and no longer functions anymore.U have a Digital Camera turn it on take the tv rmote put in the front of the Digital Camera pushes each buttons one by one all the buttons that work u will able to see a flashing white light on the camera vewing screen,because the Digital Camera can read INFERED input signal to see a output u see on the the camera viewing screen.After u test it on the front of a Digital Camera any buttons don't have a white light flashes INFERED read out than those buttons functions are shorted and dead.Try website like Remotes.com to buy the tv original remote to replace and used.

Hello,

You need to check the output voltages of the power supply to see which one goes off. It may be due to short circuits some where, if otherwise, Power supply board have problems,just not dead yet.Replaced the power supply board,will solved this problems.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.


Hoping this will help in solving the problem...

If I am unable to repair myLct3201, it would seem that I would have a remote within a reasonable price. jimjimplaysguitar @ gmail.com (except all together),hint,hint.

you can get a replacement here you could also try a universal remote control bu getting all the features to work is not usually a problem thou is not guaranteed.

I have the stand you are looking for. I will sell it to you for 10.00 + shipping. The tv is also available. It has a problem with powering up.
Call me at 314-302-2577.

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.

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.

Hope this helps and Good luck.

You do need a converter box with that model. It does not have the HD tuner in it.

I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

Hi dalie, my name is John. Welcome to FixYa. How many times does it blink. There is a problem in the circuit, putting it in safety mode.

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, 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 backlight 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!!

You need to inspect the power supply module first.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on: Please see my basic troubleshooting guide here: http://www.fixya.com/support/r5093881-lcd_flat_panel_tv_troubleshooting_guide Failed TV and Monitors: http://s807.photobucket.com/home/budm/allalbums http://en.wikipedia.org/wiki/Capacitor_plague Parts: www.shopjimmy.com Capacitors kit: http://lcdalternatives.auctivacommerce.com/Default.aspx he can make you a set of caps.

The TV is working fine on the output and display drive but the problem is related to the microprocessor section. The source selection is a digital switch and it is not being active.
Please switch off and remove cable for about 6-12 hours so that all the charge in the system is drained off and if there was any errors to the micro procesor it would have reset.
If this wont work then the section related must be checked but your experience with electronics is needed.
Because the set is working fine otherewise any small errror can damage the set in this section.
But if you can check the +5 volt to the mP and the Oscillations of the crystal in the mP , then check for command to and from the mP as the remote is switched. You can trace from the IR detector to the mP . If mP is not reacting then it can be a suspect.
But to probe more you might need a CRO.( oscilloscope)
Check this out and comment.

We repaired ours for about $5. We have a page with pictures showing the compnents replaced.

Hope it helps!

Hi,

Your power supply board is dead, u know basic electronics’ and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.


Good luck in fixing the television

Hello,

More than likely this will be down to your Y Sustain board has gone faulty, when the back is off your TV it is on the left hand side and will probably have a fuse that has blown, replacing the fuse will not solve the problem as it is the IMP under the heatsink that has gone faulty.
You should get the part number of the board and Google or Ebay for a replacement.
Hope this helps
