Check its main power on'off switch. If the contacts to this switch [inside it] has any loose connection, this kind of fault can occur.

This sounds like a very common issue.

If set is hard to turn on (have to try several times) but will eventually turn on here is what my guess would be.

Every set has a standby power supply that is running 7/24 if the set is plugged and it supplies voltages to the remote circuit that turn the main power supply and the set hence ON.

This is an area where companies cut corners by using lower rated caps. By this I mean standby usually supplies under ten volts to to trigger the set on----what they do is use a filter capacitor/s rated at say ten volts max in a circuit with 9 volts----With the standby on all the time the filter caps (electrolytic caps) dry out inside and fail.

The problem usually begins where you have to turn set on one or two times and gradually gets worse---takes longer and more tries to get it to come up.

Once its on it will stay on until turned off for a period of time.

The caps will begin to work better (regain some of the capacitance) as they get hot===hence once on it will seem ok.

The beauty of this problem is most of them happen when the set is a year or two old and all you have to do is look at them.

They are generally black and round and vary in size---they have two connections on each: a plus and a minus---easy to replace.

The tops are silver and metal looking with creases in them and if bad in this way they will be puffed up on top----the tops must be flat and perfectly so.

If this is your problem once you id them by location(make a drawing of them) you will find the plus and minus marked on the board as well as a location number for each.

Here is the critical part--on side of each cap the value is also marked like 220 uf 10vdc= 220 microfarad at 10 volts DC (maximum working voltage) if you find for example 6 puffed up and all are 10 vdc replace with same value but go up to at least 16 volt or higher rated caps.

The only issue is when you go up in voltage rated value the cap is larger so sometimes a issue of space to fit them in the board.

The reason they cheapen these sets this way is if 10 caps and you make 25,000 sets the difference in part cost for those is enough to be important to the maker.

They do not care as long as it lasts the usual 1 year parts warranty.

I have taken the time to be long winded because this really sounds like what your problem may be.

see attached photo of typical cap and if you have questions or need advise let me know---I also have a blog just started for experts here and people with questions sd-tech.blogspot.com

The solution to Acoustic Solutions problems, such as intermittant power off and flashing blue light is very simple: dump it in the trash. This product has lots of problems which are associated with memory and timing. There is no software update available, its just cheap Chinese ****.

It is a simple question but a very long difficult answer. You must start by checking from the power cord to the fuse to the main switch. if power reaches here then check onthemain board of the +B, the supply for TV. if this does not work change parts in the smps . if supply is present check supply to the processor and whether the standby circuit works, the trigger fro the processor is active. if not check. further you will have to check on the main board for any failure of the panel drive. However you will need to flow chart your action and proceed to come to the fault area. if fuse blows then the main power circuit is faulty. Check this out. Good day

The tv power supply board have dying parts call capacitors it leaking gases,it bulges up on it tops or puff up on it tops.These capacitors are dying and be dead soon.The power supply board is the board,where the a/c power cord plug into it.U know basic electronic,have tools,know basic soldering?Seaches the power supply board and replaced these dying gases leakages capacitors. Ur tv will power up normal again and work.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

Get the service manual, in there you will be given the number of the boards and what to do... have a look, I imagine, they didn't have a service manual.

I think you are looking at a power board problem. I had the same thing happen to a Vizio and I replaced the power board and it solved the problem. It could also be the input board but most likely the power board.
