Question about Sharp Televison & Video

1 Answer

Hello, I have a Sharp Aquos 70” (lc-70sq15u). The bottom of the screen has some dark spots. Any idea what this could be? Is it a simple led replacement? I am not sure if this is an led backlit tv. Trying to decide if it’s worth repairing

Same problem. TV worked night before and then would turn on but no picture or sound. Power and OPC lights blinking. I couldn't change the channel or get to the menu.
I disconnected the coaxial cable and the power for a few minutes and then plugged it back in (electric) but left the cable off. I got a message that it couldn;t get a signal. At that point I was able to change the channels. I plugged the cable line back in and everything worked fine... Good luck!!!

Hi,
Unfortunately the panel is cracked internally can't can't be repaired the whole panel has to be replaced. most times the panel will cost as much as you paid for the set. My son cracked ours when it was only 3 weeks old it doesn't take much force to ruin one.

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.

Anyone knows where white spots on the screen along the bottom of the tv screen can be coming from


The spots are part of the transmitted signal. Normally they are masked so you don't see them.

The picture on my sharp aquos tv will not display. The power light just flashes and the tv remote and power button will not turn on the screen. Menu on both will not work either


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.
