Hi


Thanks for using FixYa. The life of a projection TV is 10-12 years usually. And that of the bulb is 10000 hrs. However, the issue you are describing not tells you completely that it’s a Bad bulb. Start with checking for a bad optic block. It can also happen due to faulty focus control or due to sparks on the fly back transformer. Also make sure to check the connections of the lamp, make sure the connections are firm.

Also check whether all the cables from your cable box are fine and connected firmly. If yes then you'll need to pull off the front of the TV, behind the speaker grill there would be a panel. Remove the panel and check for a black box hanging over there. It has 6 controls on it, 3 are marked as focus and 3 as screen. You'll need to adjust the screen. If you turn these too high you can damage a tube. So, we are doing real small adjustments. Turn the color off on the TV and adjust the red, blue & green controls up till you get a fine picture. Also adjust the focus until you get a clear picture.

And, if it doesn't resolve your issue then it is an intermittent blue lamp, a bad driver transistor a bad connection on the blue CRT board.

Replacing a lamp is a costly affair, so before replacing you'll need to check all other things.
Note-- Please make sure to turn off and unplug the TV for at least 1 hour (this will drain off current from all components especially capacitors) before you perform any repairs. Also note that the TV consists of very high voltages even when it is in OFF condition.

Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks
Rylee

SOURCE: Sony KDS50A2000 power LED flashes green, then

4 blink is a fan error. This is caused by one of the three fans not spinning fast enough or has stopped completely. The fan that usually causes this error is the one over the bulb and toward the back of the set. The repair is not expensive, but to do the service correctly you must get all the dust out of the tv or the fan will clog up very fast again. Getting the dust out is kida tricky because you have to get the dust out without contaminating the light engine, if it gets contaminated you will get colored splotches on your picture. I recommend getting a pro to fix it, the repair should be fairly reasonable around $150 to do the repair. The fans are not that expensive.

How do I fix?


Probably the replacement lamp is not correctly aligned. HOWEVER, if the band is not on the bottom, but is surrounded (above and below) with good picture, the cause is in the RED color circuitry usually the 'convergence' section. This type of failure is often due to a failing electrolytic capacitor. Repair is problematic and may be in the integrated circuitry.

My sony kds50a2000 failed lastnight. Bulb only?


There could be something else that caused the lamp to fail but if it has 6 to 8 thousand hours on it that is the expected life and it is not uncommon for a lamp to fail this way.
