Screen goes black after a few seconds.

Hello,

The picture board on your monitor is bad, since it goes off after few seconds and the power led or button is on, it means the picture board of your monitor has developed fault.

The best thing for you to do now is to take the monitor to a local repairer or service center within your vicinity to help with the replacement of the picture board because the fault is not something you can fix yourself, in order not to complicate issues.

Take care.

classic Sony telling you the lamp is going bad. Replace lamp yourself it is consumer replacable.

Hello,

Can you send pictures of the power board to me at [email protected] I will check our service manuals for the model and get back with you about a solution.

"Most" newer monitors will let you know if the are no longer receiving a signal. Sounds like the backlight is burnt out. Try getting a bright (LED works best) flashlight and shining it at the screen at all angles to see if you can see any of what you were doing. If the backlight is on the fritz, either return it on warranty or buy a new one.

souns like the dc-dc convertor board that supplies the backlight gone faulty possible poor soldering on board

All symptoms in your TV shows that you need to replace its Lamp as it has been consumed its life hours and TV requires new lamp. Lamp can be obtained from Sony Website. Price is $200, Hope this info will help you to enjoy your Sony TV in coming days.

Beautiful screen, lasts about for a few minutes, goes black. Power button still green. If I turn it off, and then back on, it works again for a while. Any ideas?

After being on a little while, the screen goes black (no audio as well) for 20 to 30 seconds. Green light stays on. Then, picture comes back on and takes a couple of seconds to get up to full brightness. About 5 seconds or so after the video comes back, the audio returns.

Until this morning, has only happened a couple of times a day, now happening more often. About 3 times in last 20 minutes.

I had the same problem. I contact the manufactuer and they refused to fix it. They said it would cost an additional $100 to have it fixed. I have not even had it a year. I thought products sold in America were suppose to last longer than a year? What has happened to companies standing behind there products. Beware of this monitor!!! DO NOT BUY IT!!! LT1919WDB
