I've been looking at the 642 as a possible replacement for my lightning damaged 632 (which has been my most favorite TV I've owned). So I'm very interested in others opinions and experiences with the 642.
Perhaps someone has experience or insights into repair of the 632 and would share that with me. A very small storm passed my way and apparently a lightning strike came into my house through the phone line. It took out the surge suppressor the phone line was on, knocked phones off the wall, proceeded to destroy my DSL modem, gigabit switch, HD Homerun, DTV network adaptor, wireless access point, Onkyo AVR and unfortunately my Sharp 632. Ironically the only thing spared was the computer server which I suspect was because it had a ground wire.
The sharp would briefly power up and shutdown with an error code 32. I found the service manuals and the code indicated Start-up confirmation communication error. I proceeded to take the unit apart and the main board had burns on the traces where the RJ-45 enters the main board. So I figure main board got fried. Now things start to get strange. The parts in the service manual don't match the parts in the 632. So I was told by a few people to just replace the board with a unit with the same firmware. So I found a used main board on EBay from an LC-70LE732 with the correct firmware FM24S. Installed it and unit booted up and I was able to flash the board with the current firmware and all looked good.
Soon I started getting code 11 (lamp error) and a few of the LED strips look dim. I got a new power supply LED Driver board but that didn't fix the LED lamp error. So that's where I'm at. The TV is watchable (My wife thinks it's ok but I can see the dark places on the screen). The service manuals leave a lot to the imagination. I need to take the LCD panel out and get to the backlight LEDs.
Has anyone taken the LCD panel out of one of these units and successfully got it back in (and how did you do it)? I'm a little nervous about the size, weight and number of wires on the LCD panel. It looks to be fragile.
