Last night our Sony KV-27S20 suddenly went dark, not completely black but pretty close. In the image, any light colors appear red, skin appears black, however most of the image is all black with bits if blue here and there. All of this can only been seen after cranking the brightness level to max. The power supply is fine and I found no loose connections or bad joints.

For the last week my TV has been going to a black screen for 10 seconds or so then the picture returns. It has been continual. Last night it stopped going to black screen, but now the standby light flashes 5 consecutive times and the color went haywire. A lot of red and everything that is suppose to be black is green.
I did a soft and hard reset with no success. What's wrong and is it worth fixing? Bought new in November 2002.
The 2 blinks are an indication of over-current. This is usually because of a shorted component. The most common is the horizontal output transistor. This will be a 3-legged part attached to a heat sink close to the flyback transformer (part with red wire coming out the top). This transistor will be marked C4856 or something similar. Update this with the exact marking and I'll provide you with the full part number and approximate cost.
Usually that symptom is caused by cracked solder joints on the vertical output IC. As the IC starts heating up, the picture starts breaking up at the top with several "dancing" dark lines appearing, the top scrunches down and then when the vertical quits altogether, the screen goes completely black. A good slap on the side of the TV might make it happen faster or clear it up temporarily. If you have experience working on PC boards then you can resolder the pins of the vertical output IC but if you have never soldered parts on PC boards then allow a qualified tech to handle it for you.
