    Abba Tv Repair Service

    David at ABBA Systems is the real deal…read more I have a Sony XBR-75Z9F (75" Master Series) that suddenly went completely black. Multiple shops either told me it wasn't fixable, parts were impossible to get, or that it wasn't worth the effort because of how complex this TV is. David was the only one who stepped up and actually took the time to diagnose it properly. Instead of guessing or pushing a replacement, he identified the real issue and repaired it at the component level (T-Con / buffer board)--something most places won't even attempt. He had everything fixed and back to me in less than a week, and now the TV works perfectly again. Communication was excellent the entire time and quick responses, clear updates and he followed through exactly as promised. On top of that, he's just a genuinely nice, honest guy who clearly knows what he's doing, especially with high-end TVs. You can tell he takes pride in his work and doesn't cut corners. Hopefully I don't have another broken TV anytime soon, but if I do, there's no question I'm going straight back to David. If you're dealing with something other shops won't touch, or even something that is a regular job, this is your guy.

    I had a 2019 75 inch Samsung QLED. Worked great until one day, The screen would repeatedly flash…read moreon/off but wouldn't turn on. The Samsung authorized repair shop estimated a $900 fix. I called David and he was able to repair the faulty internal board for only around $375. And that cost was only because he had to take the tv apart and repair at his shop. If it had been a main board that was on the exterior it would have come out to much less. While here, I found out he also does VHS to DVD transfers. If you want to avoid having to buy a replacement tv...... I Highly Recommend!

    Review #656 None Elite Squad Squad…read moreMix Feelings! 1st I Have Spectrum because where I live on im only allowed to have Spectrum for TV which is the #1 reason I dont have Cable TV and only Stream... but i cant stream unless I have internet so there i do have it. 1st things 1st, the internet no matter what mbs or gbs you have its not the best. the internet is like Netzero quality which is im glad I have internet even though its not the best ..then again Netzero was free and here.. for a lot of years I was $125 for their supposedly fastest internet ..then 1 day i heard the buzz about Tmobile..thats its better..no signal interruption..just fast dependable internet..so I had it..I went to this location..signed in..waited about a hour until I finally got called ..I went up..and went up to them just like George Mcfly ..pointrd at the guy and said "Hey You, get your..." and I got cut off and he displayed a 7G modem! I was like wow! asked questions..then he gave me the best offer and for staying ..I can have this amazing 7G Internet for $41.99. No catch.. "the best offers are when you go in person" ofcourse, i had to get Mobile service ..but who cares..I dont have to purchase a phone .. so I run home..installed the 7G..and ...and ... its the slowest internet ever..horrible for gaming.. what Wifi i have ever experienced.. ive called many times ..theyve send their "Certified Expert Technicians" to not do anything..but i love the $41.99.. just not sure if its worth it..

    Absolute terrible company & business site…read more They raise prices & eliminate discounts without any notice. Bill has gone up to over $100 and the internet is spotty. Been a customer for more than 7 years and they offer no customer loyalty or discount. Service is terrible when trying to get assistance on bill.
