SOURCE: Hitachi 32LD8700 - TV won't turn on although has power

The general problem with LCD type TV's is that the power supply fails. They are very sophisticated designs that are difficult to troubleshoot and generally best to just replace the module, but sometimes there is visible damage in some of the electrolytic capacitors (visibly bulged) and high voltage rated parts can be substituted.
Hope Ya Fix It

Measure the connector from the logic board to the power supply the second pin from the left it will say Vs_ On if the set has 3.1 volts the problem is the SSB or the logic board. On the logic board there should be a solid led and a flashing led that shown that data id flowing and the problem is the SSB. The SSB is easy to replace just remember what you tokk loose and from where. You probely will save money that way. If the set is in warranty or just out of warranty contact Philips 1-888-744-5477 and see what they can do first.

If the power supply outputs are good! Then I would say the back light inverter is bad! If the screen stays black and does not come on.

Try unplugging the TV for a few minutes (discharges the ballast/ps) then plug in and attempt to power on. I have the 42P Vizio over two years old and ran into the same problem a few times. First thought was a power supply issue, but the unplugging trick worked. Good luck.

The TV is on protect mode.

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 with no receiver box or dvd 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 TV goes on protection there are only two possible reasons.

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 , 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 occur 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 state because of the video 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.

green flashing for .3 sec with solid red indicates lamp problem. and do you have the manual? If so, look in the appendix for a section 'LED indications'. that gives you the code for the indications.
Good luck..

How do i connect a surround sound system to my Toshiba Regza 32L TV


If you look at this image: http://i.testfreaks.co.uk/images/products/600x400/251/toshiba-regza-32c3030d.3770363.jpg
The back of your tv should be similar to this (I couldn't find an exact one, but it should be very similar). You want to plug in your audio cables into the red and white plugs at the bottom right, and then into your surround sound. This should work (assuming they are the same layout).
If they are different, try and find a set of red and white plugs that say "Audio out" and "L + R" or something similar to that. These plugs will work.

Green led indicator light is off on my 62" toshiba


when you turn it off your light blinks because your internal fans are still spinning allowing the inside of the chassis to cool off, hence the reason you dont watch a DLP TV and then unplug it. DLP's are JUNK

Green light blinks when tv gets prepare to fire up lamp, check internal circuits then show picture on front screen.
Red light blinking shows some kind of internal problem during circuit check and protection got activated upon some failure.
Count the red light blink as you will see 3 second long pause and post it here to diagnose what section of tv got problem.
Did you replaced its lamp in last 2-3 years?
Thanks.

The tv want come on and the power led turn from


The TV is in protect mode because an internal fault had been detected.

Try first unplugging the power cord for a couple of hours, if that does not work, then there is an internal fault.

In that case, internal parts as the PSU, digital board, convergence circuit and ballast board must be tested and eventually replaced.
