TV Repair Questions? Ask a TV Technician for Answers ASAP
Hope your having or have had a nice day
So am I right in saying you power on,the LED (Light on front)goes from red to green,stays green but no picture on?
If so is their any sound?
Hi again Jim
The problem is without doubt the firmware
I have the service manual for the 42LC2R a little different but the procedure for upgrading the firmware will be the same.If you look at all the inputs and their is no facility for service USB the firmware will have to be loaded from via laptop using a probe called "cortez",im afraid its nothing you can do.
Corrupt firmware will throw up all annoying fault conditions including the one you have described.
I have upgraded the software/firmware on many LG plasma and LCD.
All manufacturers upgrade the data if issues arise.
If the problem persists after this the mainboard will have to be changed but in my experience if the correct firmware is installed the tv usually runs ok
Hope you understand this and I hope it helps
If you dont understand anything just ask
Yes it is software depends on models providing it is the correct software and they have also provided a install manual advising "how to"
Did you read all the relevant info on web page?
I am sorry I was unaware LG provided customers with the software,panasonic do,must have been recent because it is usually tricky to do,usually you need a service remote with LG ones this is an engineers remote.
However so long as you have read the install procedure I cannot see why not,you cant back date LG software it wont go on.
The tv must start up though it cannot load when it is dead
Let me know how you go
