I'm glad you guys are here. Our Samsung (Model #TXJ2567, when switched on, has been taking longer and longer for the picture to appear. Once we get the picture the video is as clear as new. Whether the TV has been off for the night or turned-off then on, it is taking an hour for the picture to appear. I would appreciate any suggestions as to what the problem is. Thanks. Ed
It is probably the CR socket or just cold solder
I have a very similar problem on my DTQ-27S2FC. This doesn't seem to be a tube problem, because the sound doesn't come on either. The only thing that works is the relay feeding main power. The problem seems to be that the supply feeding the 9V and 5V circuits is very slow to get up to required voltage to operate logic circuits. supply feeding ~12V to these Zener regulated? supplies starts at around 4V and slowly builds - when supply reaches about 11V the sound comes up the picture blips in. Once up the picture is very good except when a bright white scene is on, then the picture pulses. I've only had the set apart long enough to know I need to find some schematics. Or find a suggestion of where to look for the supply source problem. Thanks, John
That is usually indicative of a weak picture Tube. If the set is over 8 years old, I would consider replacing it. Otherwise, a repair shop may be able to restore the picture for awhile longer.

First thing I would suggest is to check and make sure that the cooling fan is working properly. The lamp may also have an intermittent failure as well.
Do a visual inspection of your lamp. In your case check for a fogged condition. If the failure is intermittent, the lamp will look fine to the visual check.
The newer TVs have blink codes that can be use to determine if the lamp is defective. Check for the LEDs on the front panel blinking and count how many and the time intervals they blink.
If you need any further assistance, let me know.

try to look at its circuit board and look for cold solder or loose solders usually solders with crack,they might be the problem,i dont think its the flyback coz you have audio.try also look at its picture tube at the back tru the crt if the filament is ok or it may also have loose connections

Hello All, I may have an inexpensive solution to your problem. I had the same problem with my TV as well. It would shutoff by itself about an hour after it was turned on. The when I would turn it on again it would shut off after 5 to 10 minutes. Finally I got fed up. I knew it was not my bulb because the picture still looks good. I did here a buzzing if I would turn the TV on right away after it would shut off. That was do to the bulb recharging itself. I noticed the TV was extremely hot in the back. So automatically I thought it was the cooling of the set. All post I read keep saying the TV would last about 2 years to a year after a service. Which would be right because (most) service repair clean out the units before installing new parts. What I did was I opened unplugged the TV from the wall and opened unscrewed the back panel door. I used my Air compresser and blew out all the dust inside. ( A can of compressed air should do the job if you do not have a compressor) I removed the bulb and blew out the dust on the bulb as well. I did not remove the bulb from the housing unit. After I dusted the bulb and housing unit I reinstalled it. I keep my home clean but you should have see all the dust that came out. The dust covering the components overheat the unit which causes it to shutdown. It has been about 2 weeks and have not experienced any problems since. All I can say is give this a try and maybe this will work for you. This will only cost you about 10 dollars and 30 minutes of your time. This is better that Hundreds of Dollar in repair.
