Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.
Hola amigo su problema parece ser el amplificador de audio de tu tv por desgracia es un procesador y viene junto con la placa principal y es de dif?cil reparaci?n no te compliques y busca ayuda profesional ,suerte...
Your TV main board is damaged and you need a new one. You can order one on ebay and fix it yourself. Make sure you have the TV model/serial number on the back label of the TV to have the right part when ordering.
Your TV is in Protection Mode right now. A part inside the TV has failed and the TV will not turn ON to prevent other parts from being damaged. The red light blinking is an error code for diagnosing the problem part on the one of the power supply boards. The problem boards that need to be looked at is the Backlight Inverter Board or the Main Power Supply Board. There is a slim chance you can leave the TV unplugged for an hour so the TV can discharge and reset itself. But other than that, I would use the warranty if possible. The TV repair shop maybe expensive, so get some price quotes to see if it worth the trouble.
Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
http://electronicshelponline.blogspot.com/It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time.
It sounds that there is some loose contacts to some connections to your Plasma display. Almost all plasma displays will have similar configurations to display circuits, will change only with the size of the screen.

Thank you for posting your solution on Fixya.com. The problem you have described is triggered by what is known as fault protection circuit. It would be of great help if you can tell me whether the LED blinks in between each pause. This is a self-test diagnostic which pin-points us to the source of the problem.Sai.
Hello, welcome to Fixya!This issue is related to a power problem in as much as the TV turns off on it's own.The problem is consistent with overheating on the power supply board of the TV. it might have worked fine in the past, but that's electronics for you. Power surge, irregular power supply, excess power supply, etc can affect the unit thereby making it to misbehave.The power supply board of the TV has few capacitors and IC. If any of these IC's gets short or become weak, it can cause the TV to turn off on it's own.When current passes from electric outlet to the power supply board of TV. The current also goes to the weak/faulty part, then the current stops or slow and the board overheats and TV shuts off on it's own.To solve this issue, check the power supply board and read it with a meter and continuity tester, in order to detect the faulty part and replace the faulty part on the board which is short due to which power supply boardYou can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors). After replacing these capacitor(capacitors) most likely the normal operation will be restored. Or you can by a refurbished complete power board from www/shopjimmy.com to save you some stress.Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.If you don't have the ability to read the fault, then you might be needing the help of a repairman or you can call a friend that has the ability to help you out.I wish you the best of luck.Regards.
No recall,very common problems for LCD and Plasma tvs sets.The problems ur tv are having is it the causes by the tv power supply board.That the board where the power a/c cord plug into it.U have all the tools and know basic electronic aslo can do soldering work too?Yes?Take the tv aparts and check the tv power supply board carefully,searching for dying and soon to be dead components parts are calling capacitors parts.These components capacitors parts are dying and soon to be dead are leaking,it is alway bulges up or puffing up onto it tops.These dying and soon to be dead capacitors parts must be replaced.Replaced those capacitors parts are dying parts with the same Micro Fared and the voltages higher rating like 5 or 10 voltages higher will held up and with stand heat better than those old dying capacitors was in there.Or have the tvs shops services it?Or try Ebay.com to buy a whole refurbish power supply board for the replacement.
The CXXX is not important (fabricant reference only) when bying the capacitors, the importance is the (VALUE in uF, the VOLAGE and the FORMAT/SIZE) First unsolder the capacitors from the board (take notes where the capacitors goes on the circuit board and polarity as well +/- for electrolityc type) than take them to a local electronic parts reseller (radio shack/the source, etc..) and show them to the clerk, than ask for the same thing (value, voltage and size) unless you have a lot of space on the circuit board or in the enclosure, the size is less important... (VALUE in uF has to be the exact same thing and VOLTAGE has to be the same as or above)... if they are CERAMIC capacitors the voltage and value are usually coded in numbers, the clerk should be able to provide you with a replacement with a good CROSS REFERENCE TOOL (IF NOT GO TO AN OTHER STORE) they are not competent enough...
Plasma and LCD TV sets are prone to having capacitors in the power supply section fail. This is the most likely cause for the probem you describe. When capacitors fail your will commonly see one or more of the following symptoms.
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 need to be replaced. If you repeatedly turn it on, it may eventually stay on, but every time you turn it off, the TV 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 5 mins, then try.
If you are handy with a soldering iron and can identify the power supply and 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 positive it's only doing 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.
