Question about Toshiba 32AF41 32" TV
I am leaning more of a decoder issue rather then anything else on this particular problem. If this TV is analog witch I think is as I did not see a model number for it what has happened when in 16:9 aspect ratio the decoder is acting up decoder/tuner sorry there one of the same as they both handle signal.
1. check you connections
2. if this is a DVD, blue ray make sure you on the right correct resolution for this TV.
Other then those two issue's I would have it looked at if it is happening only in 16:9 witch is wide screen format usually dvd or High Def. Make sure your TV support high def as well.

Thanks for using FixYa. The life of a projection TV is 10-12 years usually. And that of the bulb is 10000 hrs. However, the issue you are describing not tells you completely that it’s a Bad bulb. It can also happen due to faulty focus control or due to sparks on the fly back transformer. Also make sure to check the connections of the lamp, make sure the connections are firm.
Also check whether all the cables from your cable box are fine and connected firmly. If yes then you'll need to pull off the front of the TV, behind the speaker grill there would be a panel. Remove the panel and check for a black box hanging over there. It has 6 controls on it, 3 are marked as focus and 3 as screen. You'll need to adjust the screen. If you turn these too high you can damage a tube. So, we are doing real small adjustments. Turn the color off on the TV and adjust the red, blue & green controls up till you get a fine picture. Also adjust the focus until you get a clear picture.
And, if it doesn't resolve your issue then it is an intermittent blue lamp, a bad driver transistor a bad connection on the blue CRT board.
Replacing a lamp is a costly affair, so before replacing you'll need to check all other things.
Note-- Please make sure to turn off and unplug the TV for at least 1 hour (this will drain off current from all components especially capacitors) before you perform any repairs. Also note that the TV consists of very high voltages even when it is in OFF condition.
Please do accept the solution if the issue is resolved or else revert for further assistance.
