Must be a dirt cheap part if they are willing to absorb that cost and just charge for labor/ unit is out of warranty.
May be a power supply issue and that is something worth checking if the supply is very reasonable in cost.

If you have this comcast Universal Remote - Red OK/Select Button here are the codes Sony 11100, 10000, 11317

if this doesn't work use the search mode

Searching For You our Code
If your home entertainment device does not respond to the remote control after trying all of the codes listed for your brand, or if your brand is not listed at all, try searching for your code.
For example, after trying all of the codes for your TV, you still cannot get the remote control to operate your TV, then:
1. Turn on your TV.
2. On the remote control, press TV once. Then press and hold Setup until the TVTV key blinks twice, then release Setup.
3. Enter 9 - 9 - 1. The TV key will blink twice.
4. Press and release the digit 1. The TV key will blink twice.
Note: Substitute 1 with 0 if searching for a Cable code, 2 if searching for a DVD, VCR or PVR and 3 if searching for an Audio device
5. Press Power and aim the remote control at the TV and press CH + one or more times until the TV turns off.
NOTE: In the search mode, the remote control will send IR codes from its library to the selected device, starting with the most popular code first.
6. Press Setup once to lock in the code.The TVTV key will blink twice.
7. To search for the codes of another device, repeat steps 1 to 5, but substitute the AUX key for the device you are searching for.
Checkcking the Codes
If you have set up the remote control using the Searching For Your Code
procedure, you may need to find out which five-digit code is operating your equipment. Perform the following steps after setting up your devices to find out which five-digit code operates your equipment. For example, to find out which code is operating your TV:
1. Turn on your TV.
2. On the remote control, press TV once. Then press and hold Setup until the TV key blinks twice, then release Setup.
3. Enter 9 - 9 - 0. The TV key will blink twice.
4. To view the code for the first digit, press 1 once. Wait 3 seconds and count the number of times the TV key blinks (e.g., 3 blinks =3) and write down the number in the left most TV Code box (at end of this section).
NOTE: If a code digit is "0", the selected mode key will not blink.
5. Repeat step 4 four more times for the remaining digits. Use 2 for the second digit, 3 for the third digit, 4 for the fourth digit and 5 for the fifth digit. Finish writing down the code in the TV Code boxes (at end of this section).

It can be a pain but once you get it down its a cake walk.

I see so many here with no sound/nopicture issues:

ISSUES:

1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have tobuy and try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.4_3_2012_1_05_57_pm.jpg4_3_2012_1_06_30_pm.jpg

When using VGA, you will need to run another cable from the audio out of the other device to the red and white RCA connectors on the back of the TV labeled Audio Input (left & right).
