SATER service centre has been repairing Sony audio equipment in Riga since 1993 — over 30 years of hands-on experience at the same address: Silmaču iela 6, LV-1012. Our history traces back to workshop No. 2 of the Soviet-era "Elektrons" factory, and over the decades we have built deep expertise across the full range of Sony audio products: STR-DN and STR-AZ series AV receivers, the TA-A1ES integrated amplifier, CDP-CE500 CD changers, PS-LX310BT turntables, HAP-Z1ES high-resolution music players, MHC-V73D party speaker systems, and CMT-SBT100 compact micro systems. We repair at the component level — diagnosing electronic boards, replacing failed HDMI processors, output transistors, electrolytic capacitors, protection relays, CD laser pickups and drive motors. Before starting any work, the customer receives an honest cost estimate. If the repair is not economically viable, we say so directly and return the equipment with no further obligation. All completed work carries a 3-month warranty. Over 186 Google reviews with a 4.3-star average confirm the quality of our service. Bring your Sony audio equipment to Silmaču iela 6 — we will sort it out.
Popular models we repair
- Sony STR-DN1080 / STR-AZ3000ES AV receivers
- Sony TA-A1ES integrated amplifier
- Sony CDP-CE500 CD changer
- Sony PS-LX310BT turntable
- Sony HAP-Z1ES high-resolution music player

Common problems we fix
- HDMI board failure on STR receivers — no picture or sound via HDMI while indicators work
- No sound / protection mode indicator blinking (PROTECTOR) — output transistors or relays
- CD mechanism not reading discs — laser pickup worn or dirty, drive motor seized
- Turntable belt stretching — unstable speed, motor hum
- Power supply clicking on startup — swollen electrolytic capacitors, standby circuit failure
- Relay oxidation in channel switching — crackling, sound dropout in one channel
- Overheating and thermal cutoff — unit shuts down after 10–15 minutes of operation
- Digital audio output (optical/coaxial) no signal — DAC or output stage failure
Sony AV receiver and amplifier repair
Sony STR-DN and STR-AZ series AV receivers are among the most popular multichannel receivers on the Latvian market. The main faults owners bring to us include: HDMI board failure (no video or audio signal via HDMI while analogue inputs work fine), PROTECTOR mode activation (blinking indicator, unit will not exit protection mode), and sound degradation — crackling, clicking, or signal dropout in one or more channels due to oxidised switching relays. We work at the component level: replacing HDMI processors and surrounding components, re-soldering output transistors, changing all channel relays simultaneously (to avoid repeated disassembly), and restoring power supply circuits by replacing swollen electrolytic capacitors.
Sony integrated amplifiers — such as the TA-A1ES — are high-end units that last decades with proper maintenance. Typical age-related issues include drying out of electrolytic capacitors in power supply and preamplifier circuits (causing 50 Hz hum and loss of dynamics), oxidation of volume potentiometers and input selectors, and output stage overheating due to degraded thermal paste on heat sinks. We perform a full overhaul: capacitor replacement, potentiometer cleaning and lubrication, thermal interface renewal, and verification of all stage operating points using an oscilloscope. All work carries a 3-month warranty.
Sony CD player and turntable repair
Sony CD players — such as the CDP-CE500 — remain popular among physical media enthusiasts. The primary fault is laser pickup failure: the drive does not recognise discs, skips tracks, or plays with clicking. We replace the laser pickup, calibrate the optical system, and verify the focus and tracking servo motors. Beyond optics, CD drives develop loading mechanism wear over time — the tray sticks, gears strip. We restore the mechanics and replace worn drive components as needed.
Sony PS-LX310BT and other belt-drive turntables suffer from drive belt stretching — the record begins to drift in speed, especially noticeable on longer tracks. The second characteristic issue is motor hum caused by bearing wear or lubricant contamination on the pulley. We fit a new belt, inspect and repair the motor if needed, and set the precise rotation speed (33⅓ and 45 RPM) using a strobe disc. We also service the tonearm — adjusting tracking force, anti-skate, and replacing the stylus if necessary. All work is carried out at our service centre on Silmaču iela 6 with a 3-month warranty.
