Question about Sony KDF-E42A10 42 in. LCD Television

1 Answer

Screen burn in?

I have a rear projection lcd that has started showing two vertical blue/pink light lines starting at the bottom of the screen tappering off about half way up the screen. The line is distinct at the outside and fade going in toward the center of the screen. The lines start at about where the black bars are when viewing 4:3. Not bad in 4:3 but very visible in 16:9.

Check the ribbon connectors for the lcds to there main driver board and reseat them. If that dosent fix your problem, than the driver board is bad. No easy fix to repair it. I have not seen the lcds them selfs be the reason for this, but it is also a slight chance.

I have 5 thin vertical white lines on the screen sound is fine.


It looks like the problem is comming from your LCD chips, they are starting to burn out and that is why you get this lines across your tv set, if you leave it like that the problem is only going to get worst
the lines will get bigger until it finally covers your whole screen you need to replace the OPTICAL BLOCK to fix this problem
good luck hopes this helps

please rate this solution !!!!!!!!!!!!!

Sony KF50WE610 Vertical Blue Lines Across Screen


the vertical blue lines indicate some interference from other electronic gadgets near your tv. it started showing up on my sony grand wega when i installed my wireless modem. i almost ordered a new rear projection lamp costing over $100 but decided to experiment. i first moved my desk computer farther away from the tv then isolated the wireless modem router by placing it inside a small glass - the vertical blue lines became lighter in color so i dedided to find another small glass that fit inside the first glass container then put the router in the double glass - no more blue lines and my wireless modem router still works.
do some deductive thinking to figure out what's messing up your tv and isolate the interference.
good luck!

Rear projection screen 152cm lg going yellow


I am guessing that this is an LCD projection set, Please post the make and model so I can confirm. In the mean time, if it is an LCD, there are 2 possiblities.

1) The lamp may require changing. Sometimes the inner surface deteriorates because of the heat.
2) The "light engine" requires replacement as the heat and light have started to burn the LCD surface. This burning starts to show up as a yellowing usually onm one side first and spreading to the other side.

Color spots on panasonic projection screen


The light engine may be dirty with dust, the polarizer filter burned, or the LCD elements burned.

As a last-ditch effort, the light engine can be taken apart and carefully cleaned using compressed air.
