In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here...

My control remote sony bravia lcd not funcion, model RM-GD004
At first, check if battery contacts inside the battery compartment for any dust of rust accumulated. Clean them well, and insert fresh batteries and check. Check its infrared emission. You can check it by using a cellphone with camera option. If there is no infrared emission, you have to check its infrared LED at the front of the remote control for damage or loose solder terminals. For this, you have to open the remote control. If you wish to get more details about how to check and clean a remote control, visit
this site. It has a post, that describes how to clean a remote control. Good luck.

My Sony KDL 4040W4100 Keeps
These trouble is commonly caused by a rusty or dirty switch. It is easily to determine what switch, try to check the power switch or replace a new one. When replacing a switch open the back cover of your tv, try to locate the power switch by looking for the power button, It is connected in a small pcb together with the volume and channel button it is separated to the main pcb connected with a wire.

Model# kdl-40w4100
Serial # 8051767
2
I have the same tv model KDL-40W4100 and around the same age. At the moment I have 16 of
these
horizontal lines
over the entire
screen and they seem to be grouped into 2 lines per row. They are also
around 4 inches and two pixel rows high. I have been looking over the
Internet
for months and found nothing to troubleshooting this issues. In the
last few weeks
more and more of these groups of lines have been showing up and now i am
up to 16 of them and it is becoming unwatchable. Any help from anyone
would be greatly appreciated. I also attached a picture to describe it better. Thanks!

Guys,
any suggestion for for this
if the video looks like it is dark on the one side and you can see image retention(ghost image of previous image after picture changes) and all inputs and menus are distorted then you most likely have an LCD panel failure and when it comes to repair unless you were able to get warranty coverage the repair would not be economical due to the cost of the LCD panel. i suggest contacting sony customer support for possible repair accomodation 1(800)222-7669

How do I turn off CC on Sony Bravia
This appears to be an repair issue.
We are experiencing the same problems. No matter what setting we use for the 40EX500, the close captioning does not seem to come on or off.
We have a HD receiver which has a setting to disable or enable. Setting to enable allows CC to be seen on the TV, but it cannot be turned off or on with the CC button on the Sony Remote. Disabling the box, then disables the CC completely on the TV.
I do not know what the issue is, and calling Sony directly is a waste of time, the holding times are unacceptable.
