The tv went onto standby and I cannot get it to work. It is approx 6 years old and I remember when I bought it I was told that the bulb would go after a few years. Is that it, and can it be replaced and what cost?

Google the model number to locate it with "lamp" and You Tube has video instructions for replacing in most models--lamp has a 2,000 hour or 2 year average life and is meant to be replaceable by the customer who owns the set.

SOURCE: sony kp-51ws510 tv blinking light 6 flashes on timer/standby

6 blinks on your model means the +5V line is either overloaded or shorted on the A or B board. You can get replacement boards at the following link and they will assist you in determining which board of the two you actually may need.

SOURCE: Sony kp-46wt520 rear projection tv: standby light flashes

Two things here.

1) This is a CRT based set so there is no "lamp" involved.
2) The standby light should be blinking a repeated count of blinks with a 2 second pause between counts. Please report the exact count here. This will indicate the circiut in which a problem was detected.

With the above information, we can provide you with a more detailed description of the problem as well as the likely solutions and cost.

Thanks,
Dan

yes replace the lamp, sony units have certain specs that the lamp must meet to operate correctly. If the Lamp you purchased is made by LTI, these lamps do not last long as they are poorly manufactured. Look at the bulb and see who is the maker if its says LTI then replace with a Phillips brand that meets spec's for sony.

Sony rear projection screen is red then tv shuts off


Can be 1 of 2 things. 1st the red tube just needs the voltage to it turned down. In the front of TV (you have to remove the lower front half of TV to access it) is a plastic square with 6 knobs. The from left to right top knobs control focus for blue,green red. The bottom knobs control voltage to each tube in same order (so lower right knob for red) turn SLOWLY to left to reduce voltage until excessive red and lines go away. If you over turn left or right set will turn off. If that does not fix it or if lines reappear then option 2 is that red picture tube is failing outright and needs replacement.

THE LED ON THE FRONT OF THE SET SHOULD BE BLINKING IN A SERIES OF BLINKS THEN PAUSE AND REPEAT THE SEQUENCE. IN ANY CASE IT NEEDS TO BE SERVICED BY A SONY AUTHORIZED SERVICER.

Sony KP-43HT20 Projection TV


5 times blinks is error code for No Good White Balance and you said that picture is very green.
As you know TV is approx 7 years old so it needs RGB gain adjustments.
If you are TV tech person or know about TV repair, let me know to guide you further. Or contact local TV repair shop to fix it.

Bulbs - Sony KP EF41SN2


Well, those are really called CRT tubes and are way more expensive than your average bulb. I would not recommend fiixing a 7 or 8 year old (is that right?) projection TV with bad CRTs
