I have the RCA R56WH78 projection TV, and I need the code/instructions to access the service menu. I have the service manual but the keys to access the service menu doesn't work, or I'm doing it wrong. The instructions say, to access the service menu, I start in the standby mode. I was told that the standby mode is when the tv is off. But when I enter the keys, it won't work. Can someone help me please.
The problem is, when I press both buttons, I can hold it for the 8 seconds, but nothing happens. I just tried it, and the screen is still blank. The first few times I tried, the tv just turned on normally. But I'm trying it now, and the tv is still off. I'm turning the tv on, and nothing. Normal screen.
I can now access to the service menu. I didn't realize that accessing the service menu was done on the tv buttons, and not on the tv remote control. Does anyone have a manual for the ITC222A chassis for the RCA R56WH78.
