Was working fine, left room for a minute came back and it was off. Red lite is on but won't turn on manually or with remote
Sounds like main board fault. But, before make it confirm, try a hard reset to this set, and check. There are two types of reset to TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here.

Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done.

Mine was doing that then it quit even turning on so I replaced the 4 Capacitors today on the power supply board that had bulged up on the top 3 had split open they where on the top right corner of the board where the ribbon jumps from the power board to the main board with ones from Jameco Part Number 606521 they worked perfect but make sure you put them in with the correct polarity easy to do just keep an eye on it. Very simple repair and took me about 30 min to take itapart solder on the new ones and put it back together all for under $10.

you have one or two bad caps in the power supply these can like devices will be puffed on the top from venting the value is wrtten on the sides replace them and you will be good to go

Call Samsung Corporation,if u want to.Samsung might,might not help u.They only warrenty tv parts and labors are only 1 year though.The tv problems u discribing are 90-95% it is the tv power supply board problems and it is the causes.That the tv board that where the tv power a/c cord plug into it.If the Samsung Corporation will help u that great.If not.U must take the tv aparts and must check the tv power supply board carefully for to be sure that the tv causes and problems.100% for sure,it is the tv power supply board it is the problems and the causes,if ur tv power supply board have dying and leaking capacitors components parts.These capacitors components parts are the causes and problems and not helping tv to power up any more,if capacitors components parts are bulging up or puffing up onto it tops.If u have all the tools and known basic electronic?Yes? The tv power supply board must have be change all these leaking and dying capacitors components?Or tries websites like Shopjimmy.com,Ebay.com to buy a whole new refurbish tv power supply board for the replacement.

In most cases the standby light might blink with different rapidity to indicate a fault relevant to the processor. It is possible that most of these indicate that there are errors in the processing section . Since there is a possible short or leak in the circuit the output driver section can take in huge current to trip the SMPS or from advice from the micro processor. Remove the power plugs and make sure that high voltage sections are discharged of the potential stored in capacitors. Look for visible signs of leak or of busted capacitors. Look for bulged capacitors or damaged components- burnt or busted. Use a multimeter to check the continuity or shorting in components, if so detach from circuit and test . If the voltage builds up and the set power ON and then shuts up then the suspected section must be checked in detail. The processor must have the +5 voltage to the function properly , the +B and secondary voltages also must be checked to infer the fault. Trace with caution and in running through the signal path , circuit trail. In some cases the fault can be related to faulty connections or poor soldering joints. Here are some tips to check out weak solder or heat related faults: 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, 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. Based on the above method you must be able to locate the area of fault and solder the sections. Sometimes large IC's- ones with more pins- tend to have drying in some pins and so cause faults related to the IC's protocol. Have a rough idea of looking into the areas to reduce the time of probing.

Thank yall so much for the help. Not a tv technician so will have to take to repair center. Will tr the hard reset. Have a call into Samsung now.
