Our television recently blew up but as it was only a couple of years old we were reluctant to just throw it away. We found a small repair shop who was prepared to have a look and see if it could be repaired. We dropped it off yesterday morning and got a phone call later the same day to say it was ready. As good as new. It cost 106lev but that was better than 5-600 lev for a new one.
The shop is in Ulitsa Mednikarska, which is behind the small square to the left of Stratilat Restaurant.
Shop is Teknika Service - техника сервиз
Phone number is 062 622057 or 0894 956995.
They repair TV, DVD, Audio, LCD monitor and white goods and air conditioners. Also they install (not sell) car CD and DVD equipment.
Thoroughly nice people, a family concern but very professional. they do not speak english so if your Bulgarian is limited you may need help.
Wouldn't hesitate to use them again.
