The service manuals are typically only available to service centers unless someone posts it out on the web. i think you can buy them but not sure what the cost is. anything in particular you are looking for?

Cable connection, when I perform channel search no channels are found??? I've tested the cable connection with other tv with no problems. Is it possible that my cable connection is busted on my RCA...

Did select CABLE in the channel scan setting, it should have AIR/CABLE setting so it can look for the cable signal or off the air (antenna) signal.
If you have the setting correctly setup, then the tuner circuits may have gone out. Some TV has the tuner on the main board, it can be expensive to replace the whole main board assembly.

Or, just make sure to use caps with low ESR, 105c, high ripple current and long life rating such as PANASONIC FM or FC series.

L42wd22 "no signal" and no audio

Exactly one year ago our TV did that. Now our TV is in the service center cause it has no screen.....just a plain black screen. However last year when we had it in we had that "no signal" message. It was not the same problem. It had something to do with wiring on the master board...thank gosh for warr. Otherwise I was told it would have been a $300-$500 repair.
Best of luck!!

HDMI Cable - No Sound L42WD22 RCA Flat Panel TV

No sound and a digital picture. i will assume you have no signal on analog rf cable. Thomson(RCA) have been having problem with these sets. The trouble stems from the digital cuircit board. We see alot of these. You used to get the digital board.. they are not availble.. so rca found the component on these that fail.. A VERY SMALL surface mounted fuse. With a lighted magnifer and some fine tip twezzers. we replace these fuses on these boards. Do you have any soldering experence..
