Customer Question

I have a 32" Soyo flat screen TV. The tv will turn on, and flash the Soyo logo - then the screen goes black. I have looked at the power supply and do not see any caps that look bad upon visual inspection. I have looked at the inverter board and source board and those also show no signs of visual damage. Any ideas woud be great! Thank you!

Hi,

 

Although the response rate on Just Answer is normally quite high, sometimes we do get backed up. I see you have been waiting for awhile for a response; I do apologize for the delay. Do you still need help with this issue?

 

Thanks,

It is a Soyo DYLT032D with a FSP power supply FSP230-5M01 and a Eastech Electronics signal board LT3200NB Main 102C2 signal board. Hope this helps!
Expert:  Tim Nolan replied 7 years ago.

I am sorry, but I cannot get any technical information for that model, I will opt out and see if another expert has information for you.

 

Thanks,

Thanks Tim. Is it possibe that I may have a bad cap even if they don't appear to look bad when I look at them? I am a low voltage and security system contractor and although I don't deal with electronics - I have a pretty good understanding of basic circuitry. I replaced one cap that I thought was bad, but no luck. I ordered 50 of these tv's for a job and had this one come back from the customer as bad, I really hate to trash it & I would really like to use it in my office as a large monitor. They are about 4 years old and of course, the problem happened right after the warranty ran out!

 

Thanks again,

 

Neil

unfortunately no alarm problems here, normally a cap will look bad if it is bad, the only way to know for sure is to check it however with a cap checker.

Tim,

 

I don't know what I did, but I put my meter on the pins comming off the PSU to check voltage - just to see which part drops off after the 1-2 seconds so I can trace back from there. My hands are a little shakey and I shorted a 5VDC pair. I heard the PSU click when I did this. I pushed the power button on the tv and the thing fired up! Its been on for about 2 hours - I am going to keep an eye on the PSU and see if anything gets hot, but for now, my dumb luck is paying off!

 

Thanks,

 

Neil
