I did a last minute search to do the repair myself before I called somebody. I found this and figured "This will never work!"
I followed his suggestion and now my TV looks better than it has in months!!! I'M SO RELIEVED!!!! Although I really want to upgrade to a flat screen LCD or PLASMA but I'm not ready for the expensive. I have had this SONY for about 6 years!!
THANKS TVDUDE!!!

I'm 58 years old. Have had red lines forever. Tonight turned tv on and it faded to blue.Kept on shutting off Red led light flashed 8 times Read your info. Decided I had nothing to lose. I actually fixed it myself. Probably just a quick short time fix but I'm happy tonight. I guess I'll start looking for new TV. Don't know if I'll go with another Sony. I've this one for 5 years. Should last longer than that (I think)

Its unbelievably easy to fix. there are 2 screws holding the front speaker cover on (there are plugs covering the screws that you take out first).Unscrew and reove speaker cover(you got to give it a bit of a tug to get it off ) then remove the piece of wood cover held by 4 screws .. Once you have taken that off when you look down you will see 6 screw like adjusters with a white painted mark on them (do not touch top row ) the green is controlled by the bottom middle screw ,, witha screwdriver turn it counter clockwise (to the left) ever so slightly (1-3mm)and there you have your TV back .. when the screen turns red use the bottom right screw and blue bottom left screw.. I hope this helps

I replaced the lamp however the green light blinks for a minute then the lamp light comes back on and the tv can't be turned on. WD-Y57 model


with that model after the tv shuts off pres the "menu" and "device" button on the front panel buttons together for about 8 seconds and then the power led will blink green. it will blink a certain number of times then pause and blink a different number of times this will be the error code for the fail that the tv thinks it is having. for example it may blink green 6 times then pause and blink 1 more time that would be code 61 check the code and repost and i will tell you the next course of action good luck

Projector screen turns off after 10-20 seconds


Is the projector receiving a source signal? if not it will power itself down after whatever time you have it set to do so when no signal is present.
Just an idea?

Check your CRT boards on the end of the tubes for burn spots, and burnt components, check the resistors to make sure they are not shorted, burnt, and they read the correct resistance. Check the diodes to make sure they conduct in one direction only and are not shorted or open.

Green flashes then tv turns off


or a new lamp. you could first replace the lamp.
the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.

Tv cuts off and green light flashes


Yup, it seems a lamp problem can give a blinking green light over the 10 times (1 - 10 times for diagnostic codes), but in my case rather than replace the bulb if it works for a minute then resets with the green light blinking, do what I did.
Take the lamp out and inspect it, it has breather screens top and bottom, if it cant breath because there clogged with dust, clean them, and you can remove the screens, use q-tips and clean the inside. I saved the cost of a lamp and it's working fine!
