Facing TV Problems? Ask a TV Technician.
Hi and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, bear with us; re-confirm and post back with the complete model number of the Sharp TV. Additionally, please describe the "...just the light on the screen..."; is the whole screen white, blue or dull black?
And even if 'no picture', is there still sound?
Appreciate the additional information.
By ".. tv is on...", does it mean that the standby light changed color to indicate that it powered on? ...or is it blinking?
Is the remote able to turn the TV on and then able to turn it off?
Have you / can you please try unplugging the TV for an extended period of time?
I tried calling but for some reason, the site shows that "...Payment for this service failed...".
Can you please reply here while it is being addressed.
Please confirm; with the TV plugged back in, it can be manually turned ON using the rear right panel POWER button ?
And the same button can turn the TV OFF ?
The described symptom almost always point to an internal hardware issue.
Are you then considering a DIY (do-it-yourself) repair approach? If yes, do you have access to and familiar with a multi-meter and even perhaps a soldering iron?
Would a link to TV repair shops serve your need then?
