Can't adjust convergence and fishbowl effect to picture

I can't adjust the convergence on my TV either manually or with the flash focus. Here's the problem, in the center my guns are aligned perfect, but towards the edge of the screen the three colors get further and further away from each other, giving it a fish bowl look. I already replaced the IC's and still nothing. I was wondering what else it could be.

Chances are the 4.7 ohm 1/2 watt resistors are open and the s.5 amp picos in line with the resistors may be open as well.

WHY DID MY VIORE SCREEN RESIZE TO SMALLER SCREEN


Screen size depends on the broadcast signals aspect ratio, the TV adjusts for that automatically, the picture can have no bands or be banded top and bottom or on both sides.

I have sound but no picture on my tv


This is a popular question. Most of the time you either need to make sure all connections are not loose or just need to turn off your tv and receiver and unplug. Wait for 1 minute then reboot.
I recommend this short video as it walks you through some diagnostics for other possible problems.

How do I reset the TV?


There are two types of reset to TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight; will be better. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/
Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done.

Samsung TV Displaying Dual Images. It appears as 2 of the same images offset from each other. There are also some lines in the images. Talked to samsung and they wanted to send a tech but I simply can't...


Overlapping video signals are generally adjustments made when turning various pots on the rear circuit board. You may need the service manual to follow the directions on how to reset and stabilize the picture. If you cannot be your own technician; you have no choice or other options.

My tv has gone some orange colour


Try unplugging your tv and anything connected to it - you might want to take a picture first so you have a reference. I would also unplug everything connected to the tv: cable, stereo, etc. Wait a few minutes, then plug in and re-connect everything.

You can also go into your TV's setup menu and adjust the picture settings - try restoring the default settings first.
