Re: grey screen with white lines



Check the bias voltages on the crt and Video output devices. Suspect the g2
source voltage being low or missing. Source is normally from the LOPT via a
fusible resistor, rectifier, and filtering cap.

I have a 27 inch Hitachi tv model number 27cx3b. When I turn the tv
on the screen is grey with white lines on it.
The audio is fine and everything. I did search to see if there is a
fix for this and found that there is a resistor, that is going bad.
The number of the resistor mentioned is 3340. I couldnt find it on the
circuit board anywhere. So i was wondering if the number is different
for the Hitachi. THe tv was free, so if its junk no big deal but if I
can fix it with a 99cent resistor i will. Thanks for the help.

Are the lines horizontal or vertical? How thick are they? Can you hear
the sound OK?
