Kao's TV Repair Service

Mr. Gao helped us fix our TV, and his craftsmanship is absolutely flawless; he clearly knows…read moreexactly what he is doing. Our TV is a 65-inch Sony Bravia (model XBR-65X850F) that we bought in 2018, and it has already been with us for eight years. When it broke down, we hesitated over whether to buy a new one or have it repaired. After a quick search on Yelp, we found Mr. Gao's information. He replied immediately after we messaged him and came to our house the very same day to inspect it.His initial diagnosis was a faulty mainboard. To be completely sure, he took both the mainboard and the power board back with him for a more detailed diagnosis. To make a long story short, two weeks later, he returned with a newly purchased replacement board, installed it back into my TV, and successfully fixed it! Since the boards for the 850F model are discontinued and no longer available on the market, he had to buy an 850G board as a substitute and modify it slightly to make it compatible with my TV. I am not professional enough to understand the exact technical details, but I am certain it took considerable time and specialized knowledge to pull off! I found the repair cost to be very fair--around 40% of what I originally paid for the TV. Some people might not find it worth it, but I am so glad I can keep using this TV instead of scrapping a perfectly working LED screen and creating a massive piece of electronic waste.

Mr. Kao is a rare professional in that he is knowledgeable, great communicator, and personable. He…read morecommunicates clearly and sets expectations that are reasonable. In my initial conversation, he explained that he had two calls ahead of me and that he would follow up on status of when to expect him. He went above and beyond what was expected. On a Saturday of a Holiday Weekend (Labor Day). He came to our house to diagnose our 77 inch Sony TV, removed a few suspect boards to repair or replace and told us it can take up to 5 days to repair if he didn't have the parts. To ensure that we knew what to expect. He called us several hours later that same day to let us know that he found a fault that he repaired and updated the firmware on the logic board. He was able to return to our home at 8:30pm to 10pm to repair and ensure the TV continued to work! He is pleasant, friendly, and knowledgeable. A pleasure to work with and would recommend to anyone

Horrible customer service from start to finish--from the person answering the phones (when they…read moreactually answer), to the technicians, to management. The technician initially no-showed for my appointment. When I called, the woman who answered the phone was curt, unhelpful, and had a bad attitude. She was completely unapologetic about the technician not showing up and did nothing to help resolve the situation. When we rescheduled, the hours were changed without anyone informing us. Once I was finally able to speak with dispatch, I repeatedly stated that I wanted to file a formal complaint. I had also made this clear to the woman who initially answered the phone. I was told that the person I needed to speak with was Ben or Benjamin. However, I was told he does not have a working extension and does not work in the office, so I was unable to reach him directly. I also told the technician that I wanted to cancel my appointment altogether. He specifically told me that if I canceled, Ben would definitely NOT call me back to hear my complaint. Because I wanted the opportunity to have my concerns addressed, I decided to keep the appointment. It has now been two weeks, and Ben still has not contacted me. This entire experience has been extremely frustrating and reflects very poorly on the company's customer service and management. I made multiple attempts to have my concerns addressed and was repeatedly passed around without any meaningful follow-up. At this point, I am still waiting for someone in management to acknowledge the complaint and actually address what happened.

I have been calling since Monday morning to get a status. They have told me multiple times that someone will call me back. Today now Wednesday morning I finally get a hold of someone and they hung up on. Don't waste your time. I've got a fridge thats leaking water and I can see the terrible reviews and now I know why.

My Pixel developed a swollen battery while still under warranty. The expanding battery pushed…read moreagainst the screen, causing it to bend and display lines. I took it to this authorized Google repair location expecting to discuss my warranty options. Instead, the staff repeatedly told me they could not repair it "per Google's guidelines." I kept asking clarifying questions, because it wasn't much of an explanation. Why wouldn't a swollen battery be not not covered, I never received a clear explanation beyond that same repeated statement. What made the experience especially frustrating was being told immediately afterward that they could repair the phone out-of-pocket for around $500. This left me wondering: if the phone is physically repairable, why is it ineligible for a warranty repair? Whether there is a legitimate policy reason or not, no one explained it to me. I also asked for documentation, such as a diagnosis, notes, or any paperwork I could review later to discuss with Google directly. The staff refused to provide anything unless I opened a paid repair ticket. Since a $500 repair was not economically reasonable, I declined. I left with no documentation, no clear explanation of the diagnosis, and no guidance on my next steps. My disappointment is not that they could not perform the warranty repair if Google's policies genuinely prevented it. It is that I never received a clear explanation and left feeling dismissed rather than helped.

Had a good intake. Fumble on the closure though. Was expecting a more seamless interaction. Got the…read moretext my item was ready and came to a long wait and lackluster service. Was also told they were understaffed and only one person working, but you could hear staff in the back of the store. Seemed a little disorganized for the structure they project when initially going over things. Also, had a pending item they were going to check with the repair I had done, and it seemed like the staff had no team communication between shift changes or responsibility hand off.
