It is taking longer and longer for my tv to turn on is something going on with the tv?

Something is changing inside the TV. Most likely a voltage from the power supply since that would affect the different circuits that are causing multiple visual symptoms on the screen, and as the voltage returns to normal; all of the symptoms go away. Suspect the main power supply board in the TV, Most likely there are faulty filter capacitors that control supply voltages by filtering out AC interference.. When they start to go bad they begin to run warm and it takes them longer and longer to start working correctly. Probably (probably) when you first noticed the problem, it went away in a few minutes and it is taking longer and longer for it to clear up.. Sounds like they are close to quitting completely !

Replace the remote is the only alternative if you are sure the remote is the cause and not the TV's IR receiver.

Either you have to take the TV into a service shop or aim a fan at the back of it to let it stay on longer getting some cool air on it :)

A primary reason for electrical overheating is dust. You might want to get a spray air can and spray out dust where ever dust can get inside the TV.

That's really a temporary fix or something that can prolong usage, but ultimately the TV will need servicing.

hd tv's take longer to come on than regular tv's, blu-ray players take longer to play a disc than dvd's. be patient, the wait is worth it, as long as it does indeed turn on, lol

definitely, something wrong with it. TV shouldn't take more then a few seconds to start, I suggest, while it still under warranty, give Sharp a call to get it fixed.

your audio board is going out take it to a shop and have it fixed

try a tech

the problem of your tv is the CRT socket replace the CRT socket it with a new one and your tv will fine.

Sounds like one or multiple Reservoir Capacitors in the Power Supply were starting to dry up. You also get problems like this from dry joints in the Power Supply. You need a technician to take a look for certain.

It sounds like you have cold solder joints poor connection.Did the shop you took it to do anything at all? This is not a fix it yourself problem set needs to be solder first.ThankYou for trying FixYa.
Have a Nice Day.
