Try to replace the Main Power Supply board first.

SOURCE: Olevia 42"

Olevia LCD 542I - Had the same issue for a week until the tv would not turn on anymore, after several attempts it came back on. A few days later the tv turned off then only the standby light was on, then lost the standby light as well. After researching the problem it could be in two areas, either the power supply or main board. Removed the back and found the power supply had several capacitors that were bulging on the top and appeared the fluid was leaking, all signs of a failed part, removed the PS and replaced four capacitorst that had shown some issues. If you can removed the PS and check for a number on the board, mine was FSP271-4F02, and find someone who has some electronic circuit capablilty, the issue may be resolved at a fraction on the cost of a new power supply.

Sadly to the end I can now explain the "problem" of my question by myself ...
Because I'm was not sure if I can handle the "problem" by myself I gave the Screen to a technican at our City with all the Information I found until this point (By the way my suspicion was the defect of something at the power supply unit). Two days later he gave me a call with the information about the error: An error at the power supply unit - spare parts => 50€, Work => 200€).
Unhappily im not yet got at soldering on screens, but for 250€ i would have made a good course for this (and if I can establish i will learn it).

So now again a bit more objectively:
Error / Problem:
TV - Step 1: Power Off
TV - Step 2: Stand-By
TV - Step 3: Power-On
TV - Step 4: Short flashing picture
TV - Step 5: Reverse to Step 1

Solution:
1. Find the defect Fuse/Safe/...
2. Buy the Spare part at eshop2.euras.com
3. Change the parts -> et voilá

Hopefully I could have been a little help for someone.
With kind regards,

Most likely, the problem is a defective Main Processor Board. This is the board with the antenna, RCA and HDMI plugs. You cant repair or replace component parts on this board, so dont even try. You must replace the complete board. The TV says Sylvania, but it is a bloody Funia TV. Several years ago this foreign company bought out broke-azzz Sylvania . They are still carrying the Sylvania name since Sylvania was a popular TV name in the 70s. Every electronic company in the USA is now owned by the Chinese, so call Funai and order the part from them. Dont be surprise if they dont have a clue what the heck you asking for. America and all electronics have gone to the puddles. Do you know why? GREED.

Above is your service and repair manual, download and use to troubleshoot. This is a classic switchmode power supply, shutting down to avoid a fire, explosion, or both. This set had developed a problem, that is so severe that the set must be shut down, This set should be removed from the Power, and in my professional recommendation, you should get a "Quote" for repair, from, an Panasonic, , Approved Service Center, this point is very important for a good result, Always contact, their local, "Head Office" Now, when you get the information you want, then you can decide as to repair of replacement. The reason we want an approved agent, is that way, all the engineers are trained on their own brand sets, they have seen almost all faults, and will get the job done quicker, and for less cost, and usually have parts on hand, also sometimes, there has been a service bulletin in issued and the repair may be subsided or even free.

With this symptom, it is impossible to tell what the exact "Cause" of this symptom is. The LED's do not tell us what is wrong, sometimes it may indicate the "Area" in your case it is the X board. BUT thats NOT where the "Fault is" thats just the part that is affected. These days unlike the "Old" analogue days it just isn't realistically possible to fix anything but the most basic of problems with todays sophisticated units. This is quite apart from the Safety aspect, any unit that can cause a firs or have an explosion, or both, is NOT to be treated lightly, and and the repairer, of the unit is legally responsible, another thing to think about. Also, one must have tools, a Multimeter, a soldering iron, a deslodering iron, an oscilloscope, a signal tracer, tools, and most important of all, a Service Manual, without which, there is no way to even begin to understand and fix it, and more importantly Program it, AFTER it has been fixed. As these days a TV, is a PC, a Tuner, and an HDTV Monitor, and more, all in one. in the "old" days TV"s were more, rudimentary, and built to last for 20 years, and a "Parts" supply was set aside. They usually used to fail for only a few reasons, and they while still difficult, were less difficult to repair. Electrical knowledge was transferable, and they could be and would respond to, This-is-the-symptom-This-us-the-Fix, But that no longer applies, as now, it can be a Fault on I squared Bus, or "Sensor" failure, or it simple may have "Crashed" just like a PC, It could be a Diode go bad, and that will stop the whole thing. You see, in the day, the sets were Very "Fault Tolerant" because they were Analouge, and a faulty, component, or more sometimes, the set would always diplay something usually, and when they didn't it was one of anly a few things, sure there are always the horrid ones, and there are pleanty of those, but all in all it was quite easy. But with Digital Electronics, it either goes, or it doesnt, there are usualy few half measures. I mean thats the definition of logic either going or not. So it can take very little to completely paralyse a set, and generally give the only sysmptom, it can, by not working, usually No picture, or the like. So you, see the list is endless almost for any given SYMPTOM, as that is what is being seen, not the cause, as I keep going on about. Also any fault, usually involves the Power Supply, it is either the cause, the cause of the damage, or it is damaged. or ALL of them. Then after you have done the electronic repairs, you then must program the set to work, and align, and set up in general, any one of those settings missed or done wrong, back to square one. So, it is nearly always my professional opinion that one should always get a "Quote" form the manufacturers recommended service center, I cannot stress how important that last point is. It is even worth the cost of shipping. you see an authorised service agent, will have trained staff, trained on their brand, also they have first hand access to parts, original parts. This will actually save you money and ensure you can actually get it back fixed. Of course asking for a "Quote" also gives on the option of repair or replace. Often my clients,do not go through with repair, unless it is moderate, but in some of the more costly jobs they see it, as do i, that a replacement, with a warranty, is a better option. As an aside here, one could then tear the TV down, and sell the Known Good bits. You'd be surprised who needs parts, i myself often must by from third party sources to effect a repair. So money could be recouped, somewhat,and help out someone else
