TV Repair Questions? Ask a TV Technician for Answers ASAP
I have had a look at Sharp technical and their are no bulletins for this model so I can only assume its something that hasnt been common
When you look at the screen can you see images in the background?
Also if you press the menu button does that come up ok clear or will it not?
From what you are saying and the set has no menu coming up either you have a mainboard issue
You have nothing to lose by trying a factory default to reinitialise all the electronics if you wish,but you would lose the sound if it didnt work as the tuning will be lost ?
Let me know
With the fault you have it is probable that it will need a part.....mainboard
Sharp will take a query from you by email but this is for customer support issues usually if the set is under warrenty,if your not they will tell you to take it in for service if they reply at all
If you want to (and their is no gaurantee its going to work) I could instruct you to re-initialise the set by telling you a specific code which isnt in your operating manual but is used by us engineers to factory default the set ie like when you first took it out of the box,so if you were watching through an antenna the set will need to be re-tuned.
I am not saying this is going to work but its worth a try and wont cause any problems if it dont as you cant see picture anyhow
Let me know please
I am sorry for the rude interruption
To reinitialise the set you need to press down on the set itself VOLUME DOWN at the set and on the remote itself number 1 and hold them both for about 2 to 5 seconds
This will re-initialise the chips
Let me know
In the manual it doesnt say anything about switch off it just says do that
Are you sure you did it right because you should not have sound as the set would want re-tuning ,so if it doesnt cure the fault their will be no sound if it does their will be no sound because everything goes like you just took out of box and was setting it up do you know what I mean?
Try switching set off and holding them buttons DONT FORGET THE OTHER IS ON THE SET ITSELF
Hi again Edith
Im afraid your probably looking at a mainboard failure or worse display interface board failure this board drives the display and can only be provided with a new display.
I think at this stage I will opt out although I cannot see any other way to resolve your problem but to initially change the mainboard
Another engineer may have more info
