The image seems to be good when there's an image. But a black screen is pinkish, or in letter-box format the black perimeter is pinkish. Seems to be a recent phenomenon. The set gets a lot of use and is almost 7 years old.
The video output section circuits has the fault. Might be a a video output transistor short. Type {Electro-help} in your search box and enter this site. It has all details.

The set might have lost the high voltage needed to light up the picture tubes,the easiest thing to check is for a loose conection in the horizontal drive transformer first ,the power supply and the output transformer area,you can try to find it by removing the back cover ,repluging the set,turn it on and with a wooden or rubber handle tap in different areas of the chassis to see if it reacts,you might have to keep pressing the power button while you are trying.If you are familiar with tv service you have a few places to check,some resoldering might be needed,you might need to check the output transistor for a short ,if the transistor went bad it did take a fuse or safety resistor.If you are not too familiar I would suggest to call for help from a servicer,I dont think is time for a new set just yet but an estimate will help you decide.Let us know how it goes or if you need more information.

The vertical output IC is most likely the cause. On a 27 inch TV the generic part number is AN5522 the location number ic IC561. Be careful of dangerous voltages within the TV powered on or off.

This is not a problem that a reset will fix. THe 5 blinks is a code that indicates a problem with the AKB circuit. There is a possibility that the picture tube is starting to fail, but that is rare. If you are comfortable working inside the set where there are potentially dangerous high voltages even when unplugged, let me know and I will provide additional details and instructions for a couple of repair options.

SOURCE: My Sony trinitron tube Tv 36" seems to be going (its 10 years old
no ....the tube will end up after 20 yrs in 10 yr old sony...
it is worth if u fix it. randomly going black means...horizontal driver trans former is the problem..or any loose contact with the 110 volt supply to that transformer,,or any loose contact with line o/p transformer.. (horizontal driver transformer may be gone
then tv behaves like this) if any other parts gone tv wont come back.... there may be a loose contact call a service pro..
Testimonial: "Great response... I basically needed to know if it is worth fixing (if its the tube) I like this tv and don't want to ditch for a new flat screen. thx"

The power supply is not starting up. The most likely cause is two defective integrated circuits in the power supply section. If you are technical, I can supply you with the part numbers and where they are located.
