Try a "hard reset" first by unplugging the set for 30 seconds. and if no help, you may have a problem with the SMPS power supply, it might have a bad capacitor or two by now. Worth repair if engine is good compared to a flat panel.
after changing the lamp, I still had the same problem as you. I contacted sony and they offered me a brand new 40 inch bravia flat screen tv replacement...at no cost! If I chose a 46" or 55" there would be a charge between $325
I can't tell you how to fix this set, but I can tell you that its not a "lamp" issue as this doesn't have a lamp. Its a 3 picture tube projection TV. the three tubes are in a red green blue format, and average about $175 for each one, not including the labor to install them. your problem, may not be the tube, but just a power supply problem, but there is a chance it is.
The thin line indicates that there is no vertical. This is usually controlled by a single IC (vertical IC). Look for a small flat IC attached to a heat sink with 9-14 pins. It may be marked LA7837 or something similar. Try resoldering the pins first. If that fails to resolve the problem, replace the IC with a new one.
Keep us posted.
That TV uses the PTK195 chassis, and the fact that you see only a thin line for each color near the bottom of the screen tells me your vertical output IC has stopped working, and is putting a small DC voltage across the yokes. I have seen this caused by a defective vertical output IC and I have also seen vertical problems caused by a small CRT coolant leak which drips onto the main board near the vertical output IC. If you do not have experience servicing the PTK195 chassis than have a qualified tech handle it for you.
