Sir good evening i have akira model 19LED211DVD my problem is no picture but have a good sound.? can you help us what is the problem here


Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

I turn my tv on and i have sound but not 1 bit of picture i have try tons of things please help


The problem is no back lights.If the back lights is not working the back lights inverter is the cause of that, there's a blown surface mounted fuses or leak capacitor.So its better to check the back lights inverter board and find the blown surface mounted fuse cause of shorted transistor or transformer.Hope it will help you.Thanks..

Hi, when i switch on my LCD, screen is coming blank, with clear sound and after few seconds the LCD is switched off automatically.


In that case or symptom,the problem is either come from the power supply or back lights inverter board.The screen or the display is totaly black when the back lights is not working. The inverter board have blown surface mounted fuses that my cause of shorted transistor,transistor or leak capacitor.Thanks.hope it will help you..

I had a akira tv remote but it could not work,,, and then the transistor poart is missing?


hi,
u can use the C945 NPN (emitter,collector, base configuration ) transistor in that place.
ok

I have a similar problem to one posted a few months ago - flashing LED on the power button, except the monitor does come on after a couple of minutes and the LED stops flashing. bdmrtn said to the other...


Look real close at the solder joints on the inverter transformer pins, and the transitors. What usually happen is that the cold solder joints will mess up the bias on the transistors or causes arcing and that will take out the transistors, you need good magnifier glass to see, you will see ring/cracking around the component's leads.

It will get to the point that the transistors 2sc5707/5706, and also still should look for bad caps.

THE MONITORES POWER LIGHT KEEPS BLINKING AND THE MONITOR WON'T WORK AND STAYS BLACK


It has shorted out transistors in the inverter circuits, also look for cold solder joints, fuse.

If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums

Why my monitor blacked out?


Failed DC filter caps, cold solder joints, shorted out transistors in the backlight inverter circuits.

Fues blown in xpower inverter 1750 plus


These fuse are often intend to protect voltage inversion. (reverse voltage)
So, if the eight fuse are blown, then maybe the voltage red and black wire were not connected to the correct polarity.

then again, even if these fuse are intend to be use as reverse protection, it may occure that transformer short out, transistor short out and many other short circuit inside the inverter as occure.

So replacing all eight fuse might not restore the unit function, they may even blow again.
Also, reversing polarity that cause the fuse to blow might have damage the transistor stage.

I am still, investigating few other problem with those unit.
I don't have all answer yet.

regards,
