The power indicator on the front of the tv is also flashing red, right. You have a bad backlight inverter. Let me know and I can help with replacement.  lone99star

Sharp aquos tv, model no. lc-70c-6500u, no audio, visual at power up, standby/power light flashes 2 times long, 5 times short, nothing else happens, what is this mean?

Sounds like main board fault. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Kdl46ex400 sony tv don't work flashing red light twice

Randomly replacing part or boards, is the last thing you should do.
Without a correct diagnose the replacement could introduce extra errors, and there is no way you could verify what is wrong. You even could damage the new inserted part. After my school I needed some years to improve my skills in the repair business. To make a good diagnose, you need things, like measurement tools and manuals. And you must follow a path to come to the defective part. It can't be replaced by a hint on the internet.
And although the flashing light can tell you (and the tech) where the error is, it can't tell you what caused it the error and what is missing or wrong. Your work, could cause some extra work for the tech who should repair this.

See the error light as motor not running. But it does not say, no fuel, no spark, no oil, defective gasket or whatever you can think of.
Please leave this to a tech. In the end it is cheaper when you did not open the tv in the first place.

Have a sharp aquos Quattro 70 " that won't come on. Power light on front is flashing a quick flash then a little longer flash. Any ideas?

We call that one fast and one slow. The only way to know the cause is going into the service menu if possible. To do that you need to "force" the TV on. These are things a repair shop should do. Going into the service menu without knowledge could permanently damage the TV.

Polaroid TV screen will not always come on.

Are you talking monitor rather than tv? I have an LG 22 inch monitor and the on off button is on the bottom, If I don't hit it right or just tap it, it won't turn off but flashes. Where do you have it plugged in? Is it with some other electronics, or right to the wall outlet? I'm really at a loss as to what your problem really is. Are you using the remote? One quick fix might be the battery's in the remote. If they don't have enough power, short or no signal will be sent to tv or not being able to decipher it.

What you have is a darfon V144 board (junk). it's a simple fix if you know how to use some basic tools and a soldering iron. Get an led (i used digikey's PN: L10041-ND) and solder it from pin 10 to pin 16 on the OZ960 chip on the inverter board. If you need the chip layout type "OZ960 pdf" in google. Hope this helps.

TV not coming on...

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

Also ensure 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.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

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

1The internal circuits are jammed because of electrostatic chargesaccumulating on capacitors, or because of a wrong voltage read by themain chip on your monitor controller board. this started the protectioncircuit.

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

If you are in situation one, then theTV 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.

Common faults that can occurr are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing statebecause of the video cable.

Try moving the video cable, and if the cable is not built in, then also try a replacement cable.

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.
