I have a 55" misubishi projection tv (55315) that is about four years old. When I first turn my tv on there is a whistling sound and pink horizontal lines on the entire screen. The problem usually goes away in about 5-10 minutes but is starting to take a little longer.

Re: Pink horizontal line when the tv is powered on.
1. White raster with no signal, washed out looking video with signal. Access the service menu, "menu 0357" use the audio button to select "video chroma" adjustments, use the video button to select item "40 - AGIW", use the adjust button to change the setting to 0, then press the enter button to store the change.

The set if projection which model here is, has arced and now each of the three picture tubes used has a tiny permanent burn mark on its screen.
That is what you are seeing, the set uses three picture tubes with screens like the old tv sets===the coating has been burnt in each, want to prove it, remove rear cover and cover any one of the three lens and that mark on one tube will go a way.
First of all, thank you for contacting Fixya.com regarding on your TV problem.
Based on your description, it sounds to me that the picture of your TV is rolling from left to right (horizontally). If the symptoms remain the same in all inputs, then this is an indication of faulty signal board part no. 930b901003-55. You have to replace this board to resolve the issue. Click it HERE for the replacement.
If it was the lamp there should be nothing. press the menu button if the menu does not come up the issue is with the tv. If the menu does come up try a second source a dvd player or game system. If the issue is only with the original source than the original source needs to be replaced.
You description of "...no video but with audio..." could indicate a number of possibilities:
power supply section;
horizontal section .
Other ideas are:
Since it has still sound, then the power supply is a least likely possibility;
Since it has still sound, then the tuner is a secondary suspect;
Since the menu shows, then the vertical and horizontal would be highly unlikely.
which eaves us the video amplifier or electronic/soft selector as the most likely culprit.
Further diagnosis would of course would require a fair
familiarity of electronic components/circuitry and safety procedures,
use of a DVM and a soldering iron. It would be to your added advantage
access to a service manual or at the very least a schematic diagram
with voltage readings. Should you be uncomfortable performing a DIY
(do-it-yourself), perhaps your best bet would then be to seek the
services of a qualified professional.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards. Thank you for using FixYa.
