Turn off into standby and on and off all over have pic an sound

Do the ballast first. That should get the picture back. The main board controls everything else.

Hi,it sounds like its time to replace the lamp,especially if tv is between 2-3 yrs .Any clicking noises? if you do it could be an issue with the board that powers the lamp it's called the ballast.Your lamp is made by Philips and it last 6000-8000 hrs ,make sure you get the original, generics dont provide same quality and life time is way shorter 4000 hrs 6 mths - 1 yr.Have a blessed life!

Please recheck Lamp Cover and make sure it is fixed in its space securely as 3 times red blink shows lamp cover error.
There is small safety switch in TV cabinet under lamp cover that has to be pushed by lamp cover if it is fixed in its position properly. That switch is not being pressed by lamp cover and causing this error.
Thanks.

when u switch on your console try holding your finger on the standby button untill u hear it beep , i think it beeps 3 times this will put it back to the origional settings incase you have accidentaly switched it over to hdmi

sounds like a compressor issue, perhaps the good news would be if its just under 5 yrs, youll have a 5 yr warr onthe compressor assy.( you should anyway) ck your manual for warr info

take this to the dealer it should be under warr. they have a 100k 10 yr warr. on seat belt buckles

ouch generally a bad rear bearing..sound god awfull almost hurting your ears to listen too??? a rear bearin replacement requires inner tub, outer rear tub, new pulley. quite expensive repair, if not covered under a warr. luckily multiple yr warr on part offered by manufactue, id cvall so see what if anything would be covered

sounds like the starting device for the compressor clicking on/off not always starting, hopefully under 5 years old cause sounds like a bad compressor(full 5 yr warr on on that)

compresoor sounds like its tryin to start but cant, should be covered under 5 yr manufacture warr.

Unplug the set, pull out the lamp module (not all the way - leave it on the track) and push it back in.

Power issues (Tv not turning on) were typically due to faulty ballast. While the TV reports a bad lamp it is the ballast itself causing the issue. Samsung is well aware and will replace both the ballast and the lamp (since the lamp can be prematurely aged but the bad ballast). After replacment most people stop having issues.
