Sony KP-E53MN11 no picture but sound Can't Post

Need advice why there are perfect sound and yet no picture. Looking through the projection lens is just a line of the 3 colors, doesn't have any image. Is problem from CXA1855S?

Looks like a straight line horizontally at top of picture tube, full line from left all the way to right side.
On second taught, I am not sure is it due to the splitter.
How to test if the splitter is good?

Aberthan;....
I have NO experience with this model TV...
However , I may be able to give you very limited help....
From the pix you posted , your TV is set on "Video 1" , with no pix...
Do you have anything hooked up to that input connector ???
Do you get the same line with different inputs ???

Not familiar with "CXA1855S"...
What is this ICs function ????...
Do you have the service manual ???....

Some of the above info may/may not help you & me , but may be beneficial to others who may be able to help...

THANKS...Smile...

Yes, I plugged in the input, sound is OK but no picture and the OSD that indicate "video 1" is where I connect the input and the sound comes from.
CXA 1855S is a Sony I^2C Bus-Compatible Audio/Video Switch (I guess it is also called Jungle IC). which I suspect.
Unfortunately I do not have the service manual.

Aberthan;....

Try this for a service manual;=>....
http://elektrotanya.com/...on.pdf/download.html

I'm on dial-up & this is a 16.4 MB file that will take a looong time for me to download...
Some advice;...
UNLESS you KNOW what the hell you are doing , do NOT go into the "Factory Service Menu"!!!!
IF you do & you mess with the wrong item , you could make your TV into a 53" boat anchor OR a 53" doorstop...
When the page opens , scroll down to the bottom under the cover page of the manual....
There you will see ;=>...
""Click the preview picture to see bigger size.
The preview is worse quality than the original pdf.
This file is downloadable free of charge: Get Manual""

Click on "Get Manual" when it appears...


Hope this helps....Sly....


Good Luck....Smile....
