HT-CT260h Sound Bar stopped working and will not power up

I've enjoyed my HT-CT260h sound bar for a couple years until the other day, in the middle of a movie, the display blinked/flickered twice and then shut off. It won't turn on now and doesn't show any sign of life. I've tried different outlets, unplugged cables, and resetting the unit to no avail. (The unit showed no sign of actually resetting, but I went thru the motions.)

 

In hopes that a capasitor had blown and it would be visually obvious, I did an inspection. Everything on the circuit boards look fine. I pulled the power supply and tested the voltage pins. All were reading 26.5 volts. The pins were labled 30.5V and 32V. Not sure if this voltage difference signifies anything. 

 

One other thing I noticed, when I plug into a power outet, there is a small spark almost every time. Again, not sure if this signifies anything, or if this is normal. I don't recall if it happened before.

 

I would love to get this sound bar up and running again. Any suggestions would be very appreciated.

 

Thanks!

Re: HT-CT260h Sound Bar stopped working and will not power up

Hi MoonBase,

 

Welcome and thank you for considering the SONY Community!

 

We are sorry to hear what happened with the sound bar. Below are the steps to isolate the issue:

 

  1. Make sure the speaker system is getting proper ventilation.
  2. Verify the AC power adapter for the transmitter is plugged into a working, electrical outlet.

    NOTES:

    • Plug the AC power adapter directly into an electrical wall outlet instead of a power strip or surge protector to minimize the possibility of a short.
    • Use only the AC power adapter supplied with the transmitter. Do not use any other AC power adapter.
  3. Unplug the transmitter and connect it to another wall outlet to make sure there is not a problem with the current outlet.
  4. Verify the other end of the AC power adapter is connected to the DC IN jack on the transmitter.

If the issue is still unresolved, service may be required. You may visit this link to locate an authorized servicer.

 

 

Regards,

~Erin

Thanks for replying, but I don't think what you wrote applies to the HT-CT260. It's doesn't have a power adapter. Yes, the sound bar is plugged in. The electrical outlet is not the issue. If you or someone could help determine if the power supply inside the unit is working correctly, that would be great. Thanks.

Your internal power supply may have bad capacitors.  The SA-CT60 which is a similar model has a known issue with a bad capacitor on the main circuit board and I have posted a fix for it (http://community.sony.com/t5/Home-Theater-Products/My-SA-CT60-sound-bar-will-not-power-up/td-p/51382...)

Re: HT-CT260h Sound Bar stopped working and will not power up

Hi Soughnie, thanks for the response. Your CT60 thread was actually the first thing I came across trying to fix this. Unfortunately, visual inspection showed no signs of a blown capacitor or bad solders. The power supply is still producing voltage, albeit lower than what the pins are labeled (26.5V vs 30.5V and 32V). I don't know if this means anything but it leads me to believe it's not a blown fuse in the power supply.

 

There are several caps, any idea which ones I should try replacing? Or any other ideas? The little spark when I plug it in to the wall makes me think there might be a short somewhere. I know enough to fix it if told what to do, but I don't know enough to diagnose it. Smiley Happy  Thanks!

[ Edited ]

The spark that you see at the wall outlet just means that the power supply is drawing current, which is normal.  If there was a shorted component on the power supply or elsewhere it would either blow the line fuse or cause a catastrophic failure.  I wonder how different these units are internally (SA-CT60 vs HT-CT260h) since externally they are nearly identical.  Does the location number I gave in the repair correspond with an electrolytic capacitor on your board?  If so, you might try pulling that capacitor and checking it with your multimeter to see if it's shot.  If not, I would check any capacitors near sources of heat such as transistors, large resistors, transformers, etc.  Those are usually the first to fail from my experience.  Good luck!

Re: HT-CT260h Sound Bar stopped working and will not power up

It seemed pretty different when I originally opened it up and compared to your photos, but I'll do it again and see if I can find a matching location number. I just ordered a small ESR meter that will hopefully help find a bad capacitor. My fingers are still crossed that that is the problem. Sure would have been nice if one were buldging. Do you have any thoughts on the lower voltage coming off the PSU pins? Thanks for your help!

Re: HT-CT260h Sound Bar stopped working and will not power up

Hello, MoonBase.

 

I've had exactly the same problem with my HT-CT260H Sound Bar. I bought it in december of 2013 and last week the sound bar stopped working. The subwoofer device and sound bar was plugged into the same power strip when it happened. The subwoofer is on, but obviously doens't work without the soundbar. I've checked the voltages at the transformer component and they are all working fine.

Did you get your problem solved after all?

 

Thank you!

Re: HT-CT260h Sound Bar stopped working and will not power up

Totally bummer. It ******, huh?!? I've taken mine apart and there are no visible signs anything is wrong. I bought a little gizmo to test capacitors in circuit and could not find anything wrong. I've given up and shopping for a replacement. I'm first going to look for a used CT260h so I can reuse the sub, but otherwise I will probably avoid a Sony soundbar. This one was not cheap and should have lasted more than two years... same as yours. Good luck!
