Car stereo and head unit repair
Head unit dead after a battery change, asking for a code or stuck on the boot logo? We repair removed car stereos in Riga — OEM, Android, classic units.
The most common story is mundane: the battery was changed or the car was jump-started — and the head unit shows no signs of life, or the display demands a CODE nobody remembers. Other typical complaints: sound cutting out on bumps, a volume knob that jumps across values, buttons that respond every other press, a dark screen while the radio still plays, an Android unit stuck on the boot logo.
We take in removed head units of any generation: factory units from VW, Škoda, Ford and other makes, aftermarket Pioneer, Kenwood, Alpine, Sony and JVC, Android stations such as Teyes and Atoto, and cassette units for retro cars. Bring the device already out of the dash — we do not do installation work in vehicles.
We look for the cause at board level: rebuilding the power input after a voltage spike, replacing the audio output IC, fitting a new USB socket and a fresh volume encoder, repairing the backlight and display contacts. Instrument clusters, parking sensors, cameras and dashcams are outside our profile — we work on the head unit itself and its close car-audio relatives. You hear the estimate before the repair, work starts only with your approval, and repairs and replaced parts carry a 3-month warranty.

Factory (OEM) and Android head units
Factory units — VW RCD 330, Škoda Bolero, Ford 6000 CD and similar — are usually worth repairing rather than replacing: they sit in the dash without adapter frames and keep the steering-wheel controls working. Their typical faults are a burnt power input, a dead display, a jammed CD mechanism and a lockout after several wrong code entries. All of these are board-level repairs; we do not decode radios, but we do fix the faults that stop a unit from accepting its correct code.
Android stations fail differently: they are tablets in a stereo housing, with tablet weak points — ageing eMMC storage, an overheating processor in a cramped dash bay, unstable power converters, a delaminating touchscreen. The symptoms are freezing on the boot logo, spontaneous reboots and ghost touches. Diagnostics shows which block has failed, and the estimate always comes before the repair.
Why the vehicle electrical system kills head units
A car 12 V network is twelve volts in name only: engine starts and jump-starts produce spikes, and the head unit meets them first. That is why our most frequent patients are units with burnt input protection — a blown fuse, a shorted suppressor, a dead regulator. The damaged block is quick to localise, and this repair is rarely expensive.
The other typically automotive ailment is vibration and temperature swings. They crack connector solder joints and oxidise contacts: sound starts dropping out on rough roads, and the clock and settings reset after every trip — a sign of a broken keep-alive supply (the yellow ISO wire). On the bench we power the unit from a laboratory supply, load the outputs with speaker equivalents and simulate a rough road — gently tapping and warming the board until the intermittent fault shows itself. We repair what we find and verify the result under load.
