I ordered a power supply to repair my TV after searching on-line. The part was shipped to me and received in a timely manner. After installing the part & having the same issue (the power light blinking but the TV won't come on), I requested a return authorization.
I took care to wrapped the power supply board in bubble wrap and even more plastic than when received. I also sent it back in the same box it came in. I wanted to ensure it did not get damaged.
I never heard back from the company and never received a refund. After several emails, I called. I was told that they had emailed me back to tell me that board was chipped. I explained that was not possible due to the care I took in returning it. I advised that I never received an email. (I checked while I was on the line, also checked the spam folder, no email). The guy said he would send pictures and that I would need to file a claim with the postal service.
I'm sure they realized that I did not ensure the package because due to the way I packed it, there was no way it could've gotten damaged. (I would like to add that I had a job previously where I was responsible to pack & ship items so I know what I am doing.)
In closing, I am not happy and would not recommend getting anything from them. I am out of over $70 which is a lot to me.
