✔ Real Spanish company with our own premises in Marbella (Málaga)
✔ VAT invoice with every purchase
✔ Every part with its reference checked against its physical label — what you see in the photos is exactly what you get
✔ 30-day returns and, on top of that, the eBay Money Back Guarantee covers you 100%: if something doesn't arrive or isn't as described, you get your money back

Buying from us today has its reward: the care of a shop that's earning every single vote.

STEP 1 — The torch test 🔦 (the one that separates a smart purchase from a return): in the dark, switch the TV on and hold a torch right up against the screen. Can you make out an image? The panel and the main board work: your problem is the backlight (LED strips, driver or the backlight stage of the power supply). No trace of an image? Keep reading.

STEP 2 — Standby light and ear 👂: is the standby LED steady, blinking or dead? Can you hear relay clicks or channel audio? Each combination points to a different suspect in the table.

STEP 3 — Find your symptom:

💬 Unsure about your diagnosis? Message us BEFORE buying with your TV's full model number and the symptom: we'll tell you which part you need, no obligation — we'd rather advise you for free than process a return. And if the part still doesn't fix your fault, you have 30 days to return it and get your money back (return postage paid by the buyer).
