I have a 21" Konka television that is 20 months old. Model K2166EZ.
When i turned it on the other morning, the picture was shrunk and eventually turned off. it then did not turn on again until later that day. it struggled to turn on, but eventually came on. after a while however the picture will distort and shrink and eventually there will be no picture at all. i try to turn the TV back on with the remote but it wont turn on. if i leave it for a while i can turn it back on but soon after the same will happen. what is the problem? is it easy to fix? and will it be expensive? Thank you for your help.

When you say small do you mean shrunk up top and bottom as well as from side to side. You definitely have a deflection problem either horizontal or vertical.If the picture just shrunk top and bottom you have a vertical deflection problem. Do you have the service manual for your model? If not let me know and I will email you one. Describe the shrinking issue a little more and I should be able to give you some guidance.
try Check first all the output voltage in the secondary of the chopper transformer if regular voltage acquire. check secondary switching circuit feedback towards the opto isolator and syscon.
Assuming that HOT is OK.
Sounds like you've got a vertical deflection problem causing the shrunk picture and finally a solid bright line. As to the loss in brightness you may be losing screen voltage to your picture tube.
Probably it is time to shop for a new tv since cost of repairs may be too much.
