Will not turn on

I have a NIKO SV-3206 that I have never had any problems with. this morning my wife tried to turn it on. She said there was a loud POP and then nothing. The red/green light in the lower right hand corner that would indicate power on or off is not lit. is there a reset button or something?

    What fuse? Where?

  • richardlyons Feb 05, 2009

    While this was not exactly a Fix the information provided was extremely useful and pretty much matched what I had been told by the technician at Viewtek who apparently is the distributor and service center for Niko TV's. They are located in Walnut CA and can be found by doing a search on the web. I have and can provide the address and phone # if anyone needs it.

I had exact same Issue, Was able to resolve the no power issue by replacing Diode zd4 (15v) and Q7 (15v Transister) on the back of the power board, and now i have sound but no picture, but while troubleshooting i replace caps so i think i installed a bad one somewere.

I have not worked on your model of set. I can tell you generically my opinion from experience of servicing many TV sets.

Once a fuse or any failure to operate properly occures in solid state devices there is an actual fault. These systems have very well designed protection circuits and are computer controlled.

The pop you heard is most probably a direct failure of a component that is most likely feed from one of the main power rails on the circuit board where it operates. The first area of fault may be in the main power supply. In these sets there are several levels of power supplies. Because the pilot light on the set is not lit, I would assume that the main power supply has failed.

It is also possible that a power drive circuit has failed, and the main power supply is in the protection mode, or has also failed. Normally, if there is a failure and the power supply can still function enough to operate the uPC, the uPC will issue a warning. This results in flash codes from the pilot light.

If the fault is not complicated an experienced TV tech may be able to troubleshoot and fix the power supply at the component level.

Normally these sets are serviced by swapping out boards. The tech will try the suspect boards and leave in the boards that make the set work. The next step is to follow the service manual using the calibration instruments to confirm and adjust the factory level setups.

TV sets are not simple devices. There are many power drive circuits that operate various areas. Flat panel sets have some basic principles that follow that of the CRT sets, but for the most part they are very different and very complex in many areas.

I tried to find for you any direct authorized support contact information for your TV. I was not able to find any.

These sets can be fairly expensive to service. You could try a local service center. Ask for an estimate before servicing the set.

When buying a new set I would suggest for you to stay with a big brand name type set. Whatever set you choose find out if there is direct factory level service in your area for the set.

I hope this helps you out to understand more about the problem.

Niko Sv3706 - When plugged in the Red idle power light is on but when turned on the light goes green then completely shuts off with no light nothing on screen when turned on

Just fixed mine, when plugged in red light comes and goes, sometimes it ststays on but when I turn it on the green light comes on then off. Opened up tv, there is a heat shield of some sort,take off, there is a board where plug goes into the wall,it also has three more plugs plus a ground that is screwed to the tv.I looked at the board and there were two capacitors that were bulged and had brown stuff about to come out the top. They were 1500uf 16v 105c, I changed them only I made them 25v instead of 16. And boom life was good. Good luck and sorry for my spelling.

Turned it off on the set...can't turn it back on...power button keeps blinkling red

The electrolytic capacitors in the power supply become damaged by heat.The top of the caps will swell up lookinglike a bubble instead of being flat they will needreplacement.the caps should be replaced with high temp caps.This is a commen problem with these sets

This morning the screen is black...

The black screen with audio working ok is the inverter card.
Just replaced mine. It is CMO part number VIT70002.00

The inverter provides the high voltage necessary to drive the cold cathode lighting.

A new card is about $180 but shud save having to dump the set.
Card is located on left side of the display (as viewed from the back).
