Unstable image on television screen: Hitachi Model # 27CX3B

The TV is a Hitachi 27", Model # 27CX3B. Upon powering the TV on, the image suddenly flattens to a thinish horizontal line that runs the entire width of the screen. This line appears right at the centerline of the screen and stays there. The rest of the screen is black at this point. The line has colors and movement, as if the entire image is still there, just extremely compressed vertically. The problem usually happens within the first two minutes of operation, but has also happened randomly at other times. If you gently whack the top of the cabinet, the image will sometimes revert to normal and stay that way for a while, sometimes for hours. I am comfortable working with electronincs and dischargings capacitors, but I need some advice on how and where to look for the root cause of this problem. It is a perfeclty good TV otherwise and I don't see a need to spend upwards of $500 on an LCD for this room in the house. TIA for any assistance you can provide.

If the sat feed is on channel 3, and the TV is tuned in and still does not get the feed, check the feed wire to be okay. If all is okay, there is a possiblity that the tuner module in the set has failed.

You have a problem in the convergence circuit. Most likely the stk392-110 ics need to be replaced (with stk392-150's or better) and you are likely to have some burned resistors in this circuit as well.

This really is not a repair that an amateur should attempt, although it's pretty straight forward for anyone experienced with repairing big screen sets. Our shop charges about $300-350 for this repair in your home.

Hitachi Standard T.V.


Some of the problem could be a weak or damaged picture tube - especially if it encountered rough handling in the move. Other possibilities are bad capacitors in the power supply and deflection circuits which are common with this aged set. No adjustments come to mind that could permanently fix these symptoms.

Screen flashes


I can't say that I have seen this on a Hitachi, because I haven't, but I have seen it on older Zeniths. The problem with the Zeniths was in the power supply. An electrolytic capacitor changes value and slows down the switching of the power transistor. This means sometimes it works, sometimes it doesn't. Replacing the cap solves the problem everytime. I would look in this area. Good luck.
