These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/

I am having the same problem, what was the solution to this problem? And how much did it cost to fix it?

www.shopjimmy.com or have a repair tech fix the board itself. The buffer boards are getting harder and harder to find.

That problem is usually have 2 causes..Its either power supply board or main board..

Please take this steps on how to determine the problem:
1. Open the back cover.
2. Check the power supply output...It should have 5vdc for the main board..12vdc or 16vdc for the audio and 24vdc for the back-light inverter..
3. If those 3 voltage supplies have encountered voltage drop...The problem could be on power supply board..
4. If the power supply output is normal..The problem could be on the main board...
5. If the problem is power supply you should check if the capacitors are bulged on the top and try to replaced it..If you can't do that you can purchased new power supply board..
6. If the problem is on main board there is no D.I.Y repair on that so you need to buy a new main board that fits to your TV..
Hope this solution will be helpful..

Thanks for using fixya...

Consult the owner manual or if you have not tried it--unplug the set for a while and plug back in to see if set will reboot.

This is a fault solution which can be checked and corrected by you assuming that there is no component failure. There is a high possibility that the components over a period of heating and cooling, tend to bring on a problem of dry soldering. So my advice is to check the set for some loose joints that have played on to give you these erratic shut downs or poor performance. The best way to check for loose connections is to tap lightly when the set is powered on, if there is change while tapping then it seems that there are DRY solder joints. Remove main plug, the covers - with caution of high voltage, check for dry joints, and use a good soldering iron to solder all suspected points. Sometimes the fault occurs when the set warms up; if so you can simulate the heat using a hair dryer on the suspected areas, try with the power supply, distribution, Processor controller, driver controllers on the A/V related sections. Also the use a FREEZE-IT spray can simulate the components to cool and show up the fault. It can also be related to WEAK ELECTROLYTIC capacitors as the value can reduce in time. Based on the above method you must be able to locate the area of fault and solder the sections.

This means that the logic control is working on the controller unit but the audio section - audio amplifier drivers - are not responding.
So it seems that the audio preamp section is faulty and it can be confirmed only if signal test or a voltage check is done and traced.
The changes from the logic control must be traced to confirm the section.

First of all you have to check the Va - 60V and Vs - 80V voltages at the power supply point. If any one of the voltage is missinig there are two possiblities for that. One is the power supply itself and the second one is the sacn drive modules for X and Y. If the scan drive modules are faulty then the or short then the Va Ans Vs voltage from the power supply will drops.you have to measure using a multimeter is there is any short circuit in its power supply in put point. When the voltages from Va and Vs point are missing then this will indicated by the blinking of power light. To rectify the problem you need a good knowledge in electronics. Aslo need the necessary equipments for measuring the voltage at different points

Its probably busted it can be replaced but not really worth it just use a remote

If you are able to do this then i will sent the service manual for the same if you can sent me your email address through fixya. Which will help you to troble shoot the TV.
ok

Yes you should take it to the shop as there is very high voltage stored in the set for a while after you turn it off. It may not be the power supply; a shop can test it for you.

When troubleshooting these units, there are always several variables to consider. First check to see what last occurred with the unit such as did the children play video games, did the electricity go out due to bad weather. You may see that there are many possibilities but let's focus on what occurred last to the unit. Once we determine what happened last, we may isolate the actual cause of the problem. The actual cause may be associated with projection issues, older versions (Picture tube), interference from devices located nearby, and even a radio turned on and located really close to your unit. This is normally known as electromagnetic interference to electronics and is very common with the error you have provided today. Please continue to look for anything EXTERNAL to the unit before looking at the internal components, check your system input settings, verify your display settings, and confirm that your properly connected to your cable service.
