Sharp tv My sharp model 14B-SC behaves in a way that it takes long to come on and when it comes on the screen takes long to brighten up as in it comes on slowly and has lines and no rasters or sound,the power indicator is on red doesn't change to green

The MOST LIKELY problem is in your power supply inside that will require either a good deal of technical skills AND desoldering equipment, OR a ton of grey matter and a burning desire to learn something new, (in which case you're subjecting yourself to possible severe electrical shock). To go on, you'd need an ESR tester to check out the status of capacitors AFTER you've located the power supply internally. IF you've gotten this far, you CAN order exact replacements from Digi-Key in Thief River Falls, Minnesota. PLEASE pay attention to my word of caution about electrical shock, and I wish you well.
