TV wont come on

Every place I've checked talks a blinking power red light in front. My TV doesn't have the power on blinking red light when I turn it on but still wont show any picture. The day before it did this too. But I left it alone and came back to it and it turned on right away.

Blinking power light indicates fault. From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. These are called blinking codes. To know more about these blinking coded, visit the site. It has details about blinking codes to many brand TVs. Pull up older posts. If you search the site in Timeslide option, which can be selected from the drop down list at the top left of the display window, it will be easy to locate the related post. http://electronicshelponline.blogspot.com/

If you open the back,look at the can shaped items.If any of them have the tops bulged out,they need to be replaced.This should solve your picture problem,unless there is something else wrong.What is happening,is they are heating up,and the picture goes out.I bet the longer you have the TV off,the longer it stays on?Hope this helps.Thank You very much!

SOURCE: Power won't turn on; red lights blinks occasionally

It sounds like a bad PSU, or a bad solder joint on one of the boards.

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.

Need upstar TV Codes

I found that common LG codes (056) mostly work with UpStar (that uses LG panels, and generic electronics modules).

Watch out for stripped or missing hardware, including on table stand pod and VESA brackets, with UpStar's sloppy quality control. Also, they've reversed AC line Hot and Neutral and caused other problems in their California service facility, shipping fire and electrocution hazard TV's.

My sony kdf e50 12u wont turn on red light blinks twice

Your TV is giving you a code, something is faulty in the system, usually 2 blinks of the red light indicates, Load on power line is shorted. I also would check the bulb also to make sure it doesn't need replacing.

Popping noise and now won't power up. Red and green indicator lights blink on front of tv.

start by checking the power supply in the set and if not able to do that consider taking it to a shop for an estimate.

Tv wont turn on, the power indicator nor the remote receiver light does not light up, the 3rd circle on the front of the tv blinks red!! But it wont come on regardless, tv is only 2 years old, what to...

The blinking red light means set is in shutdown because of a short inside the tv.

Someone to begin would have to open it and check power supply voltages inside the set....that is the first step.

Hello

If the power light blinks slowly,

you've tried to turn on the TV during

the lamp cooldown cycle. Wait

approximately 30 seconds, and the TV
will turn on automatically.

If light blinks, pauses for about a

minute, and blinks again: the lamp is

trying to turn on (TV will turn on

when successful). If TV doesn't turn

on and sequence continues, the lamp also
needs to be replaced.

To order lamp call 1-800-338-0376.

Have your TV serial number

and lamp type available (you'll

find this information on the

sticker that's on the right side of
the TV).
OK.
