Good morning to you!
When the screen goes black, have you tried to go into setup on the remote. Adjust the brightness of the screen.
Or as I am sure you have done to restart the TV when the warning sign comes on the screen that the TV will go off affter 5 min.
The classical action is to disconnect both the router and the box that keeps all the stations in it. Disconnect for 2-3 minutes, connect again.
I do apologize for not knowing the name in English. ( english is not my mothertounge)
Hope this can help you on the way. Then there is always the user manual that can be downloaded free and look in the troubleshooting page. ( I did that the other day, had lost the paper onr)
If your screen turns to back after a minutes but the sounds is normal..That problem is very common to all flat panel specially to LCD TV..
OK,I need to know first if your TV having a back-light when the picture went out after a minutes.If that so the possible problem is T-CON board (this board is the responsible to produce a video on all LCD TV)..
If you don't have back-light the problem is inverter board again..But before you order or install new inverter board try to find why the inverter board gone only on few weeks after you install it..the possible problem why the inverter board faulty for the short period of time is higher/lower input voltages (24vdc) comes from power supply..try to check it using volt meter or multimeter tester..it should be read 24vdc on meter..let me know if the voltage drop or higher to 24..
If the 24vdc is fine the only problem is the condition of inverter board maybe its used or partially faulty when you buy it..
if you have more queries and clarification regarding my solution please feel free to reply on this tread...
Probably caused by a power supply nearing its death.
Try to verify this by placing a portable fan to the side of the set with airflow directed at the vented sides.
If this lengthens the operating time, there is a good chance that some minor components in the main supply have developed low values of capacitance and higher losses which worsen with warmth.
Listen closely at the vents with the sound turned down to attempt to detect a squealing sound while the TV is in its failure mode; if you find this, it is also a sign of power supply trying to die.
A tech equipped with a capacitance meter that measures losses at the same time, could find and replace the weakened parts without a whole lot of labor and little cost for parts.
Yup, it seems a lamp problem can give a blinking green light over the 10 times (1 - 10 times for diagnostic codes), but in my case rather than replace the bulb if it works for a minute then resets with the green light blinking, do what I did. Take the lamp out and inspect it, it has breather screens top and bottom, if it cant breath because there clogged with dust, clean them, and you can remove the screens, use q-tips and clean the inside. I saved the cost of a lamp and it's working fine!
I had same problem. Tech's said the power was noisy. I cleaned up the power but the TV still did exactly as you describe. Problem will progressively get worse with longer bouts of flickering.
I was under warrenty and sent the TV back. After 3 months I am still waiting for a repalcement.
