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: Problem connecting my PS3 to my Sharp Aquos LC-C3237U LCD TV

Your PS3 set itself above the max resolution your LC-C3237U. Most likely the PS3 is doing 1080P, but the highest the Sharp can do is 1080i. So do this:

1. Connect PS3 to TV (you can use the current cable or analog cable)
2. Turn on TV and set input to port PS3 is on.
3. Make sure PS3 is connected via correct cable.
4. Power on PS3 via power button and HOLD IT for 5 seconds (release after the second beep). It should automatically configure your PS3 to the TV's native resolution for all settings.

Diagram will be impossible to get.
Check the power supply; look for bad caps with leaking/bulging tops, check to see if you have standby +5vdc at the power supply connector, the front red indicator will not be on if you do not have this +5vdc standby voltage due to shorted out Q7 and ZD4.

Tengo un telefono daewoo adp 2200 duo y uno de los terminales me pone sin reg en la pantalla sin dejarme hacer nada y aparte se me ha bloqueado, alguien me puede echar un cable, gracias

sugiero que lo lleve al taller de reparacion. Es muy dificil instruirle como hacer algo, pues no se trata de software sino de Hardware, a menos que usted tenga mucha habilidad en electronica digital avanzada, para hacer reparaciones delicadascon telefonos sofisticados.

Dios le bendiga.

Tarjeta madre

Haz busqueda con el modelo y la marca que usas en, hay muchos vendedores que despachan a todas partes del mundo.
No sae si sabes ingles pero en el espacio de busqueda(Search) tipea la marca por ejemplo Asus y el modelo AB-12345. Escoje la opcion BUY NOW cuando obtengas los resultados para evitar concursar en la subasta y saber inmediatamente cuanto cuesta.
