|Brand: Emerson (Funai)
Chassis: ? Unknown at the moment, I'm at work I will edit this post when I get home
Manufactured: September 2009 J
Other: 120 Volt AC 60 Hertz 155 watt, 3 HDMI, 1 component, audio out, digital audio out coaxial, 1 antenna in, 1 RCA YRW, 1 s-video, and a service terminal on a 32" 720p LCD HDTV
My TV has worked flawlessly since the day I bought it. I have two ALMOST identical televisions; I will start a separate thread for the other TV. I own, and have fully read and studied the service manual, schematics, and user guide for this television. When attempting to place my other TV into service mode via the hidden button behind the remote control faceplate/sticker, I also placed the second TV into service mode. As I understand, my son was watching the DVR and had pressed 'info' on the other remote. The screen then began flashing multiple colors red, then green, then blue, then white, then black, then shaded from top to bottom black to white, then shaded from left to right black to white, then repeating the entire sequence without delay. When I unplug the device and plug it back in, it turns on normaly, displays "Digital television" (as normal) and then returns to the same issue. Remembering that I had read something about this procedure, I quickly skimmed through the manual and reread the following excerpt
|1. Turn the power on. 2. To enter the service mode, press the service button- then [POWER] button . 3. Press [INFO] button unit to initialize the LCD television. 4. "INITIALIZED" will appear in the upper right of the screen. "INITIALIZED" color will change to green from red when initializing is complete. |
Maybe the screen is stuck in initialization mode, or maybe I don't know what I am talking about and it is something different entirely. The television does not respond to any commands from the remote (the 'POWER' button should exit this as far as I understood) or on the TV.
Note: "INITIALIZED" is never displayed
Things I have tried:
Pushed every button on the TV and remote control
Verified my remote is working (for some reason a couple buttons work to control my Eden Pure heater)
Unplugged it for 4 hours and then plugged it back in.
Swore at it.
Things that I have:
A multi-meter with AC/DC/Ohms/diode testing abilities
A giant illuminated desk mounted magnifing glass
A soldering iron with experience soldering surface mounted components
RTFM: Service manual with included schematics and parts list
Grounding wrist strap
Ability to identify dangerous HV components (EX: capacitors) and safely discharge them
Note: Numerous pictures of a solid color doesn't seem helpful, but at your request I will present them. For the time being a blank sheet of computer paper will serve as a good representation of a color. I will be editing this post to correct problems and to fill in extra data, as I am typing this on my buggy phone away from home.
