Hi,It sounds like a light engine problem Sony is having.Basically the light of the lamp goes through tunnels that have mirrors that direct the lamp to 3 main LCD chips,These 3 LCD chips are blue,green, and red they blend to create the image and colors.When they start to fail you'll get color discoloration like what you are getting.You will need to replace the optical block because unfortunately they don't sell the LCD chips by themselves.GOD BLESS YOU!

Hi. Not shore of this model but could be a bulb replacement is needed, Or one of the filter covers may not be making contact.

The red light is indicative of error rather than working ( green ) or standby ( orange ).
I hope you get it sorted.

I have a Sony KDS-50A2000 and when I try to power it on, the green light flashes like normal and then without the screen ever lighting up, the power light flashes red 9 times, then pauses and repeats this...


Now that you have the blink code, Google your make and model with blink codes added to the end. This will show you links to sites that will tell you what the nine blinks mean.

My sony kds-50a2000 picture is green why? I replaced projection lamp the picture was great but now the picture is terrible everthing seems to have a yellow tinge to it and green seems to be dominant...


The problem is the optical block and nothing else but. Contact the dealer from which you purchased the set to see if you qualify for Sony's extended warranty on this very, very expensive part, which may be covered by a class action lawsuit Check here http://esupport.sony.com/US/perl/news-item.pl?news_id=367&mdl=KDS60A2020 The lawsuit covers all the KDS models. It seems that Sony continued making these rear projections even though it knew the optical block failed prematurely. When you get it fixed, go to setup and make sure the cooling fan is on HIGH and power saving is ON. Both of those features will extend your TV's life, including the optical block and the projection lamp. Further, bring a portable compressed air tank to the TV and, with a narrow nozzle, empty it into every opening in the set's back. At least once per month, check for dust settling on the rear of the stand behind the TV -- when it gets thick, get the air tank.

I have the same problem with my unit. I've been removing the bulb and just replace it back and unit will work again. I probably need to vacuum or check the fan out too.
