Question about Zenith Z46Z83D 46" Rear Projection Television

2 Answers

Zenith 46" with a "hour-glass" picture.

My 46" Zenith rear projection TV now has a permanent "Hour-Glass" shape picture. It started out that it would come and go, but now it just stays. I have pulled the convergence board out, but I do not know where to get it checked or repaired/replaced. Is this the most likely problem? any chance it could be something else? I also cannot adjust the convergence on the TV.

Replace convergence ic's and 1ohm resistors near ic's check all solder connections on convergence board also check 110k ohm resistor in front of H.O.T on main deflection module.

If the hour glass figure is a seperation of colors that appear to be convegence mis aligned, then, the convergence ICs would be the problem. If the picture is clear and you have a bending on the sides then the pincusion circuit in the horizontal circuit is where to look. Be careful of this circuit, it does control the high voltage. The only way to have a board checked is to have an Authorized Service Center look at it. It does, however, sound like there is a cold solder joint in the power supply that has gradually opened up and now is permanantly open. Call Zenith (LG) to see who they recommend.

Just recently my GE 46GW 948 46 in. Rear Projection Television when turned on goes from a good picture to an hour glass shape and an almost 3d like picture.When I turn it off then on I get a good picture...


Sounds like a loose solder connection on the Convergence board or the convergence power board. If you are savvy and electrically safe, tap on the boards with an insulated screwdriver to see which has the loose connection, and you can resolder to fix. Repair from a service center = $150-300

Picture goes into an hour glass shape. red/orange color on one edge of the hour glass and green/blue color on the other edge.


You have a bad cap or two in the horizontal deflection [Pincushion problem] and you may have to look for a burned resistor. Use your vision to inspect burned areas on the board, this will most likely tell you where the problem may be. Area should be between the Vertical and Horizontal deflection. Look for the flyback transformer that is the board you are looking for! Hope this will you a good start. Thanks for asking!!

Hourglass Shape


If there is a hour glass shape to the image but convergence is normal, there are 2 possibilities. You either have a pincushion correction problem or if the hour glass seems to be moving, it will be an open filter capacitor in the power supply.

Unless you are electronically inclined troubleshooting this issue will require a factory trained service technician. You can expect to spend $300-$400 to fix this.

Picture shaped like hour glass


You have a PIN CUSHION problem, is usually a bad capacitor or open resistor in the above cicuit. Check all the caps around the horizontal output transister for ESR leakage.

Tv picture shaped like hour glass


The link you posted has been deleted, so I cannot see the picture you posted. If the sides bow in like an hourglass and the red, green and blue colors are still aligned then there is a horizontal width or pincussion problem, but if the sides bow in and the 3 colors have separated and are no longer anywhere near aligned then you have a convergence problem, both of which should be serviced by someone with experience in servicing projection TV's.
