Mitsubishi VS-60705, Turns on/Turns off.

Unfortunately you will need an experienced TV tech.
This unit will need 2 ICs STK392-110 for 1 has shorted and caused damage to the 2nd as a result blowing 1 or 2 pico fuses in the power supply.
It is an involved job and may be somewhat costly depending on the pricing in your area.
Hope this helps Normal 0 false false false MicrosoftInternetExplorer4

There is just three lines that show red, green and blue.

It has been my experience with Sonys that those three colored lines indicate that the set is having trouble with the data communication lines. The hitch is that a model as complex as that one has as many as five seperate clock/data lines and if any one of them goes down the set will exhibit your symptom. It will take a professional to track down which line is causing the problem. I've seen audio output IC's as well as tuners cause the problem.

Video distortion

You need to take your tv in and have the picture deflector re-aligned.  This doesn't cost much, My dad had to do that to his a few months ago and it cost 30 bucks.

No picture

Sound like you lost Vertical Deflection.  Youshould not have a line across the screen because this could destroy the threeCRT Red, Green, and Blue (Picture tubes) if left on to long. There is a protection circuit built in to protect your CRT’s.    Check on the PCB-SIGNALboard (Tuner located on this board) transistors Q-206 Collector should be around 1 Volt Base and Emitter 0V. If the voltage atthis point is greater then 5 Volts the Vertical output IC-401 (Mounted on heat sink 7 pin inline IC) is bad, Part # LA7845.  Pin Voltages should be PIN 1= 0V, 2= 34V, 3= 32V, 4= 3V, 5= 3V, 6= 33v, 7= -6V.  Data sheet located at

Mitsubishi VS-60705 red lamp replacement

The part you are describing is actually the red picture tube, not a lamp. The tube will come dry and you will need to disassemble the lens assembly on the old tube, drain the coolant (antifreeze), reassemble the parts and seal on the new picture tube, fill with fresh coolant, install the new tube, reconnect all wires including the dangerous high voltage lead, then realign the yoke and entire convergence circuits. This is not something that should be attempted by anyone without experience. If you try it yourself and the seal is not working perfectly, the coolant will drip down on your main boards and the set will be ruined. If you slip while lowering the new tube in the chassis there is a good chance you will crack the tube's neck, and that tube will be useless too.

Mitsubishi VS-60705 - picture flutters vertically and horizontally

This sounds like one of the 9 volt regulators on the small signal board is going bad, supplying less than 8 volts. I have seen this is several of those sets. The IC needs to be replaced and if you do not have experience in servicing projection TV's then I suggest letting a qualified tech handle it for you.
