In short
Forums mention Carli capacitors, C1/C2, C601/C602 and 820 nF (often marked 824J) when an LG OLED will not start. They usually mean yellow film capacitors on the power supply board.
Silkscreen names (C1, C2, C601, C602 …) vary by revision. There is no single universal position for every chassis. What matters is capacitance loss — not the forum nickname.
What forums mean by C1/C2
This is what the wear looks like in numbers: 17.32 nF and 89.5 nF instead of 820 nF. To measure them, the film capacitors must always be removed.
Community posts often say “replace C1/C2”. That is a local label on one board revision — not an LG service code for all models. Other boards label related film caps C601/C602 or similar.
When comparing photos: always match your EAY/EAX board. Blind soldering “because the thread said C1” can hit the wrong pads.
- Carli / yellow film caps, often 824J ≈ 820 nF / 500V
- Forum labels C1/C2, C601/C602 — revision-dependent
- Measure only when desoldered: clear drop below nominal (often far under 820 nF)
- Symptom cluster: no start, clicking, blink code, intermittent
Symptom chain and blink patterns
Classic: TV won't turn on, clicks, standby LED missing or red LED blinks. Some see 3×, 4× or continuous blink / boot-loop — patterns vary by series; no binding universal table.
Deep dive: won't turn on. Blink triage: red LED blinking. Click-click no picture: clicks twice.
DIY soldering vs tested board — clear recommendation
Power supply board EAY65689423 (65 inch), removed. We replace the film capacitors with every repair, because on these power supply boards they are always aged, even if the actual fault lies elsewhere.
Proper capacitor replacement can help — with correct specs, clean soldering and power supply board knowledge. For most users the risk is high: residual charge, primary side, cold joints, wrong caps, collateral damage.
AmparioWeb therefore recommends for most people: a tested replacement power supply board or fixed-price repair instead of hobby soldering on a mains-side board. Cheap used boards often carry the same aged Carli film caps.
Safety notice
Mains voltage and charged electrolytics are lethal. Unplug, wait, discharge before desoldering. Never solder under power.
Unsure? Keep the set closed and use Repair.
The large electrolytic capacitors can still hold up to about 400 V after switching off. After unplugging, wait at least 2 hours, measure with a range of at least 600 V and only continue once the voltage is below 30 V if possible.
What AmparioWeb offers
We see the Carli / 820 nF wear pattern in practice, map the right power supply board via EAY/EAX and supply tested boards — or repair at a fixed price.

Frequently asked questions
- Are C1 and C2 always the Carli caps?
- No. C1/C2 is revision-dependent silkscreen. Other boards use e.g. C601/C602. Always check your board.
- What does 824J mean?
- 824 ≈ 820 nF, J = tolerance; often with 500V on yellow film caps (frequently Carli).
- Is swapping two caps enough?
- Often capacitance loss is the main cause — not always the only one. Measurement and a tested power supply board are safer than blind DIY.
- Why not DIY for most people?
- Primary side, residual charge and solder quality. One mistake can cost more than a tested board or fixed-price repair.
- Which article covers the dead-start pattern?
- LG OLED won't turn on.
