Re: Circuit City ''esa'' TV picture curves in on sides
Curving in on ( hour glassing ) the sides is usually the indication of a bad regulator IC. Since it occured after a move, you may also have a bad solder connection or smal crak in the board. To check for cracks ( assuming you have unplugged the power and are relatively comfortable doing so) shine a flashligt from the top of the board ( with the components on it ) and examine the bottom of the board. If a trace is broken you can often see it this way

It sounds that the E/W circuit has the fault. This circuit is also known as pin-cushion circuit. If this circuit have any fault, curved vertical lines through-out the edges of the screen will be the result. Repair to this section circuit is somewhat skilled work. You should first find out the faulty component/s at this section circuit. It will be best to contact any service technician.
hi there.im not familiar wih the model,but your fault lies in the east west correction circuit.excessive width usually means a short circuit e/w modulator diode,with the curved sides.normally,a narrow picture with curved sides points do dry jointed/open circuit polyester capacitor.if a firm slap has an effect,then its most likely a dry joint which makes for an easy life.the vast majority of east west correction circuits are based in tle line output stage,and generally not complex to fix.hope this helps,regads,steve.ps. look for s/c by 299 and by 228 diodes,check those..
picture is starting to curve in from the sides like the shape of an hour glass.
Is the tube shot?
is it something less costly?
YOUR PROBLEM is in pincushion correction circuit.call skilled tech to fix it.
it will not take much time.
The curved picture indicates failing parts in the pin amp section and probably some faulty parts in the scan amplifier sections. The set is being turned off by the uPC because there is a fault indicated, and it is going in to protect mode.
Its Sounds like Convergence Circuit,If you take the Back off and look on the right side you should see a Board with Big black Ics Mounted beside a Large Heatsink,Mark the wires where they go and Make sure the POWER is Off Pull the Board out and Inspect the Connections from the ICS,you find Circle Breaks,They need to Be resoldered and That should fix the Set....
Have you had any kind of magnets close to the tv set? I had a brand new sanyo do the same thing. I had pulled the speaker box out of my truck and stood it up next to the tv (not thinking about where I put it). Turned it on a few hours later only to see a messed up picture. I moved the speaker box to get behind the tv and the picture got better. Moved the speaker box back to the truck and after a couple of days the picture was back to normal. These were 4 large magnets on these speakers. Maybe I helped some!
