There are some fuses inside the set. If you are technically minded, look for one glass fuse and several fuses that look like resistors, but are a green color. Otherwise, I would say you could be looking at a few to several hundred dollars of repair cost by a technician. If you need to have someone look at it, I suggest looking at this website to see if there is a local repair person in your area.

Screen turn green tv is 57 rear projection


Good Day,
It appears that you may have a green drive issue. Try adjusting the Sreen Control it is located in the front of TV.
1) Remove Speaker Grill (it just pulls off) start at one end, 2) Remove cover (5-6 screws), 3) Adjust control. The control is located on lower right side towards bottom. A small black device with 2 rolls of controls, adjust the center control on bottom row counter clock wise, until you get a black and white picture.(adjust with color control to min).
If this does not work you light bulb (CRT) is bad about a $750.00 repair.

Good Luck, Big Irish.

The tv just randomly turns off by itself


Check to see how many times it blinks when turning off and then look for the codes for Sony tv blinks. this will tell you what's wrong. This set is notorious for Shorted tubes.

No sound no picture


This is a common problem with older Philip Magnavox projection sets. Over time one of the IC chips on the main power board begins to fail. You can find replacment chips and repair instructions on www.magnavoxhelp.com.
