You possibly have a failing hi-voltage module or fly-back transformer going bad. If it has a fly-back transformer, It's not worth the trouble. Some repair shops will sell you a module. Call a repair shop for help.
Rulds2008 is probably right. I had the same problem, but have no TV repair shop near me. So since I have experience fixing computers, I decided to repair the TV myself. I initially repaired the Lamp, but the TV still flashed all three lights. Called Samsung and they told me that I might need to replace the ballast, but it would be best to bring it to a repair shop. The repair shop offered to come out and look at it for $150 or bring it in for $120, even though they were about 30 mins away. Ordered both parts on www.Samsungparts.com and got them in three days. Still had the three flashing lights. Took apart the entire TV (googled it on youtube) and vacuumed and dusted the TV and took apart the color wheel (about 20-30 mins). It was completed busted. Found out that if the color wheel is broken, it will not send a signal to the ballast to tell it to start up and power the lamp. So if you have replaced the lamp and/ or the ballast and it does not light up, it is more than likely that it is your color wheel (buy it on ebay or amazon, got it in three days versus a 3-4 week back order on company sites). Also, make sure the power switch on back is being pushed upwards and not downwards or the TV also will not start. Total parts cost me ($400) versus having someone else fix it and charge me double with labor and parts. TV is better than ever. Hope this helps.
There is a smt located at 7404 [C-6 Bottom] A common problem, does the tv make a sound like it wants to come on? Location 3239 should be small resistor, 3414 another resistor and a driver transformer at 5402 if it looks burned. See MCM electronics website and see if there is a kit to repair this. Or ask for part #s as per location of problem area mentioned. What you will be doing is changing the timing so all the components will come on at the same time. If this is done correctly you will notice the top of tv screen will flash red, green and blue lines. This will be the new norm each time you turn it on. But it will be OK. This is what the flashing green light is telling you. signed the Green Lantern7!!!!!!!
I had this same problem, i took my tv in to a local repair shop and the guy there told me it was due to the fact the sensors that tell the tv the lamp is in place where bad. He repaired the wires going to it for about 65 bucks.
when a television turns off by itself and flashes as you say, it indicates that there is a problem inside the tv. If you keep trying to turn it on you may do more damage. It could be something as simple as a faulty fuse inside. If you have no expierience with electrics I suggest you get it checked out by a professional. I had a similar problem with another tele model and it was the fuse in the back of the tele that needed changing. I did try to this on my own but unfortunatley didn't have the right fuse so i took it to a repair shop and he done it really quickly.
After some quick checks, it looks like, unfortunately, you have a lemon of a TV. First some basic info. All late model CRT TV's use the high voltage power supply to create all of the voltages it needs to operate. Which saves on parts & costs. The high voltage transformer used in these power supply's can be susceptible to failures & apparently your model is more prone to this than most.
When you said the picture started to distort, what exactly did it look like? If the transformer has not failed then maybe 1 of the power supply filter capacitors is shorted & causing the power supply to shut down. (a safety feature) A local TV repair shop should be able to determine the problem within an hour.
1 thing to try before calling someone, is to see whether the set needs a software reset. Unplug the TV for about 4 hours & then plug it back in. If the problem still exists, then you will need to contact the repair shop.
Dont know if its the same model but Ive seen a few with a cold solder joint on a switching relay in the Vertical circuit do this.. (Be careful if its a CRT TV.. 27.5KV is common off the flyback transformer).. 27,500 Volts.. Good luck!
I'm sorry, I don't have a solution, but I seem to be having a similar problem. When I turn my TV on, the green light comes on like it's powered up, but then the TV turns itself back off and the red LED light flashes. I can't do anything to turn it on or anything.
