Tv goes on then right away a blueline across the center then goes black the power light starts blinking and stays black


It is an indication of faulty on the vertical section. Nowadays tv will automatically shuts off if you have a problem on the vertical output I.C. to protect your tube for burning the phuspor right on the middle of the screen which will affect on the picture later on.
I've adviced you to look for a qualified technician to isolate and replaced the faulty parts and do resoldering for some dry joints because sometimes dry joints damaged the parts.
Thanks for using fixya...

Locked tv


You need to buy a remote for that TV. They're available online for around $39. This site has them in stock, but you can shop around to be sure its a good price. When you receive it, turn on your TV and press menu on the remote and turn off child lock. Click the Remote here:

SCREEN GOES BLACK AFTER 1 MINUTE


In electronics dust has nothing to do. cleaning will not solve your problem your problem is due to trouble in vertical section. mostly it is due to electrolytic capacitor in vertical section is defective.it is common problem. also check supply to vertical section. "THE SCREEN SHRINKS TOWARDS THE TOP OF THE SCREEN FOR A FEW SECONDS BEFORE THE PICTURE TURNS UPSIDEDOWN THEN TURNS BLACK." is called fold over. regards thanks

Screen tuns black after 15 seconds and comes back after about 15 minuts


The solder joints on the vertical output IC have cracked. This is a very common problem on those sets.

Tv screen goes black for a few seconds


do you get sound while screen does black? what do you mean by "until eventually it has turned black and will not come back"? is it black from the minute you turn the tv on untill you turn it off? if sound is good but picture is black, it may be the resault of a fried monitor tube, in this case replacement will cost alot. if sound is dead also, them it is probobly power supply related issue. get out your DMM and measure the voltages in the power supply. When the screen goes black, is there still regulated B+ going to the circuitry? Do you still have HV? Is the filament of the CRT lit? Does the set still have a raster (you may have temporarily increase the screen setting to see it)? Do you measure any of the flyback derived B+ voltages that go to the video processing, tuner, Vertical Deflection, and other circuitry?
