TV Repair Questions? Ask a TV Technician
Thanks for using JustAnswer
Is the power light blinking once every second please?
Their are 3 things that can cause this bad firmware/a bad invertor (controls the backlight)/the backlight itself
Please see if the set will go into service mode by holding down Channel Minus and the INPUT button on the set itself then plug into wallpower or come out of standby (try both)
If the set comes on this way your set is not fixed but is in safe mode you will see characters on the display using the remote arrows navigate to lamp errors and let me know the number could be 0 to 5 or even 0 to 30
Let me know if it goes into service mode or not please
Its the power and input buttons you hold down did you do this?
Its not going to play ball
How long have you owned the set from new please?
Yes the INPUT and CHANNEL DOWN (sorry my fault not power )must be held down together whilst you power up
Let me know
OK basically I was asking you to do that because in service mode (if it would have started up)the lamp error menu would have told me if you indeed had a faulty invertor or backlight but as you have just found out its pot luck sometimes that it may not even go into this mode due to the fault....
Your back to my original answer now the firmware is out you cant do anything
The invertor may be replaced but this is a 3 to 1 gamble as it could be the other 2 issues
The backlight nobody can do anything about as it basically is part of the panel (screen)so wouldnt be economical to replace
In my experience with these and other sharp sets its been the backlight as the connections inside the panel are poor
I would contact sharp and complain www.sharpusa.com find the contact email and explain what I have told you, I have seen on many occasions sharp and other manufacturers redress the customers when pressured as this should have gone much longer than 2 years
Indicate the 1 blink a second error code and what I have told you it could be use this text to back up your claim for them to do something about this
Hope this helps
Let me know if I can do anything else please
That may be the case but your argument is that if its the backlight it should have lasted longer than 2 years.....
No theirs no way of knowing by looking it needs to be changed, the firmware cant be loaded because the set is dead if its this
As I say I have seen many sharps with bad backlights and this isnt an option for replacement due to cost and can only be done in a lab by a tech
Sorry this is turning this way....
Let me know what happens and explain to them what I have told you....
Many Thanks for accept/feedback
