I have a sony kdfe50a10 and the screen has been invaded by blue splotches. What's up?


Hi,
The Light engine (also known as an optical block) which is essentially the projector part of your TV is failing and needs to be replaced. Sony has extended the warranty on some of its models so you can contact Sony to see if yours is still covered. If not it is outrageously expensive to fix easily over $1000.

No blue colors projected on screen


Only a few causes for this problem. "Splotches" are usually caused by dust in the light engine which can sometimes be blown out using compressed air. Pink picture is caused by either data or burnt lcd card. Procedure for data is: put tv to ch. 3 and turn power off. simultaneously press input and power on set for three seconds to access service menu. Be very careful not to change settings other than what needs changed. These adjustments are changed using directional arrows. Navigate to "memory init" then hold (r) arrow button for 5 seconds. You will know if it worked. Then exit and/or turn set off. Please let me know if this is successful as I have additional info you may need. Good luck, Russmann.

Hitachi 50V500 TV: has a red line that outlines faces or text


It's a light engine defective part. Hitachi knows about it and if you call their customer relations department, they will refer you to a dealer in your area to come and diagnos the problem. Once Hitachi can verify that's the problem, they will ship the part to the dealer. We had our part in 2 days and had it installed today. No more problems. TV looks brand new. We had to pay the installation of $400 but the part runs around $1500 and Hitachi covered it. We felt like $400 was worth the $3600 we bad 3+ year ago when we bought it. The color will only get worse if the light engine is not replaced. Good Luck! It was an easy fix!

Pink Screen


There is a service bulletin for this problem - you need to reintialize the memory settings in the service menu - I have a pdf file showing how to do this.
