Fault with main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. 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/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
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.
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, NatureOneFreak
