Re: Screen blacked out, no sound or pix

The set had a bad vertical output IC and when the IC heated up it took out something in the power supply. Most likly in the sweep supply, that supplys the voltage to the vertical IC. If your not a tech, Please call one, as A TV set is not a place to experiment with. A good tech may even be able to repair the module as Zenths are made to replace the entire board when theres a service problem.. Go to, click on technical assitance then finding the board you need by putting in the model # and this will come up with the board price to give you an idea on the replacement cost for parts and see if you want to invest that as well as the labor cost. Good Luck

Tv screen

you picture tube is weak.
take the back off and rotate the screen control left, then advance it slowly till you just get the pix.
It may last a little longer, but be prepared to buy a new it is not economical to repair(expensive)

No picture

you may have turned down the screen control
It is the lower one on the flyback transformer
Just advance it enough to get the pix back. If you advance it too much it may get retrace lines in the pix or shut down.
turn very slowly.
Thanks Guy

Picture is dark

sitnlisten - yes it does appear your pix tube is getting weak,but we may be able to turn up the flyback alittle to brighten up the picture.If you take the back off you will see the flyback-large black unit with a wire going to the round rubber cap on the back of the pix tube.Look at the flyback there are usually 2 adjusters one marked focus the other screen,just turn up the screen a little bit at a time.If you turn this up too much you will wind up with retrace lines on the screen.You may also want to check the pcboard ass'y for a sub bright adjust,and same thing small adjustments.If this don't help your pix tube may be too far gone.I hope this helps. cooltek Feb.1/08

crt beam current too high causing shutdown as you know. Check cathode voltage of each cathode, normal levels depend on picture is around 130-150V. Missing 200V to crt board. Screen voltage problem normal 300-500V. Flyback or bad crt. ABL circuit problem. Jungle IC.
