SOURCE: lcd sharp tv flashing green light

Try unplugging the unit and while unit is unplugged hold the volume up button and channel down buttons down and while depressing both buttons plug the unit in. Let go of the buttons and the unit should come on in the service mode. There will be a small k on the screen. With the sharp remote press the channel up button once. This should bring up a menu that will show a lamp error line. If the lamp error is = to 5 the unit is in lamp error shut down. User channel down to highlight that line and curser right arrow to highlight the lamp error #. Hit the enter button to clear the lamp errors. Now unplug the unit and let it sit for a minute and plug back in. I hope this corrects the problem. If the unit does not come on by doing this or if it does and you do not find lamp errors the power supply pcb may have been damaged by the surge.

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
connected.

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.

When I turn the tv on it came on for a minute then started flashing on and off then went blank but the power light keep flashing off and on with a blank screen.


This problem is easy to repair. If when you turned the tv on and it had sound and picture for a second or two, and the power went off and the power green light keeps flashing on and off, it is a bad CCFL backlight lamp inside the LCD panel which has 10 of these lamps in it, but only one is bad. Replace the lamp and the tv will power on. What the tv is doing is, it has stored a lamp error code on the main board and turning the power off. The replacement lamp is part # RLMPLA029WJN1 and you can buy them at www.encompassparts.com for $19.49 ea. Go to their web sight and sign in as guess to order. I can give you step to step instruction on how to check how many lamps you will have to order if you need me, too. You will have to take the tv apart to check them.

I originally purchased a LC-32SB24U and wound up needing a replacement because there was a black line going accross the top of the screen. Sharp didn't have any of that model so they sent me a LC-32SB21U...


Don't feel bad. You didn't do anything wrong.
They sent you a TV with a bad power supply board for the
screen. The TV is trying to power up the screen, but it can't. Because of a defective part somewhere on the power inverter board for the screen. That is why the power/opc light is flashing.

I would call them back and and make them replace the TV.

Dell Monitor 2001FP Blank Screen


From your description your backlight is going out. The fluorescent light when it begins to burn out tries to draw too much power. Your inverter is sensing this 'too much' power draw and shuts down power to the back light. Replacing the backlight is the most technically difficult repair of an LCD, and most repair shops don't even offer this service. I recommend that you sell your LCD 'AS IS' on eBay or a similar website. The Power board and the Control Board are both usable parts that can be easily salvaged from most Dell Ultrasharp monitors.
