i had the same lines on my 65' mitsubishi tv after replacing the DLP chip. after going back over everything i realized that the casinf that holds the chip in was not in the lock position. i took the chip out and replaced it then turned the little locking mechanism to the locked position. now my screen is perfect. hope this helps.
Ur tv have convergence problems before,that why tv getting colors lines somtimes alot,sometimes not.The 2 STK convergence ICS was defective.Now the 2 STK convergence ICS are now totally dead.The shop will cost u $300-350 for parts and labors for the 2 STK convergence ICS,and it supporting resistors.
You have a failure in the vertical circuit. Service can run between $75 to $150 depending on your area.(In home repair will cost more) If set is older then 3 years and under 27" recommend replacing it.
Could be serious...but first check the screen modes (for split screen, format, etc) to be sure the tv is set up properly for the picture you are trying to watch. Switch the input to a DVD or something similar. Is it the same? If not, you have a mode/resolution problem with the tuner and perhaps some other device.
Here's something that might also be useful. After you turn on
the set, and get the regular red blinky lights, hold down the Device
and Menu buttons together for about 5 seconds.
The Power light will start to flash in a two digit sequence.
For example, 3 flashes, then 7 flashes = 37.
Here are the error codes, and the corresponding problem:
12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filter cover is open.
34 = Lamp abnormality
36 = Light Engine (DMD or Lamp Fan stopped)
37 = Exhaust or Lamp Ballast Fan stopped
38 = Lamp Temperature High
39 = DMD Temperature High
41 = Short is detected
44 = DVI cable between FMT and Engine disconnected
