I used the Monster "Screenclean" kit, which left a film on my screen. I am not happy with it. Any suggestions on a different product which will remove the film?

If the TV goes in standby, then it is in protection mode.

Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , starting the flashing light.

If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

On LCD Pay particular attention at inverter and power board, power board can be inspected looking for bulged or leaking capacitors, then tested with a multimeter. The inverter is more difficult to test , there is need to read voltages, should be done by a tech. Also the LCD controller board can cause same problem

On Plasma, test Sustain (Ysus/Zsus) / Buffer boards , cables to plasma, digital board and power board.

On Rear Projection : check lamp, lamp ballast, power board, and convergence.

On CRT TVs, check ballast , flyback transformer, CRT, Tuner, Convergence.

SOURCE: green light is on but screen is black

It's either the backlight lamp or backlight inverter is busted due to a power failure or fluctuation. Here's how to determine which is which:

  1. Grab a flashlight.
  2. Turn on the TV.
  3. Shine the flashlight onto the screen.
  4. If you cannot see any display even a faint one, the backlight inverter is dead, else the backlight lamps are busted.
  5. Replace which ever is the culprit.

SOURCE: My sharp aquos 32' LCD has a heavy green tint to

My sharp tv also had a green tint and resetting to facotry setting did not work, what finally worked is making sure that all cables were inserted all the way into the tv and receiver. Someone else advised this for another Tv and it worked on my sharp so it is worth a try.

Sounds like you have bad capacitors somewhere in the TV. If none of them are bad, you could also have loose grounding screws on the inverter shield. It is common for this TV and simply retightning them will keep the backlight on again.

My flat screen hd sharp aquos color turns green when we are watching it. it is only 3 three years old. what can this be? thanks

I'm not sure if this is the same, but people were green no matter how i adjusted the tint, and lacked overall color. I doubled checked the component cables, taking each one out, and putting it back firmly,
Picture is back to normal. Easy fix.

Sharp Aquos 32" screen size too big!

Check your cable remote. You might have it set to HD zoom. This happened to us when our little girl got a hold of the cable remote.
