Garis pada skrin dan touch yang tak jalan hampir selalu masalah HARDWARE, bukan software. Garis menegak/melintang, separuh skrin gelap, atau warna pink/hijau pelik biasanya panel paparan (LCD/OLED) atau flex connector longgar, selalunya lepas jatuh atau kena air. Kalau touch tak respond atau touch sendiri (ghost touch), itu lapisan digitizer. Restart & buang screen protector dulu; kalau masih ada, ia perlu tukar skrin. Backup data sekarang, garis ni cenderung merebak jadi skrin hitam penuh.
Lines on the screen and unresponsive touch are almost always a HARDWARE issue, not software. Vertical/horizontal lines, half the screen going dark, or odd pink/green tints are usually a display panel (LCD/OLED) or a loose flex connector, often after a drop or water. If touch won’t respond or taps by itself (ghost touch), that’s the digitizer layer. Restart & remove the screen protector first; if it persists, the screen needs replacing. Back up your data now, these lines tend to spread into a full black screen.
Tengok skrin phone tiba-tiba ada garis menegak warna-warni, atau bahagian bawah dah tak boleh tekan langsung, memang buat panik, sebab phone masih hidup tapi macam separuh mati. Kadang skrin kelip-kelip, kadang touch sendiri tekan benda yang kita tak nak. Artikel ni terangkan apa punca sebenar setiap gejala, mana yang datang dari panel paparan, mana dari digitizer touch, dan mana dari flex connector longgar lepas jatuh atau kena air, serta langkah cepat yang patut anda buat dulu sebelum kena repair.
Seeing sudden colourful vertical lines on your screen, or the bottom section no longer responding to taps, it’s genuinely alarming, because the phone is still on yet feels half-dead. Sometimes the screen flickers, sometimes touch fires on its own and taps things you didn’t want. This article explains the real cause behind each symptom, which come from the display panel, which from the touch digitizer, and which from a loose flex connector after a drop or water, plus the quick steps to try first before a repair.
Gejala & punca: display, digitizer, atau flex?
Symptoms & causes: display, digitizer, or flex?
Skrin phone sebenarnya dua lapisan yang bekerja sama: panel paparan (LCD/OLED) yang keluarkan gambar, dan lapisan digitizer di atasnya yang baca sentuhan jari. Kedua-dua ni disambung ke board melalui flex connector yang halus. Gejala yang anda nampak biasanya tunjuk lapisan mana yang bermasalah:
A phone screen is really two layers working together: the display panel (LCD/OLED) that produces the image, and the digitizer layer on top that reads your finger’s touch. Both connect to the board through a delicate flex connector. The symptom you see usually points to which layer is faulty:
Match your symptom:
• Garis menegak / melintang, panel paparan (LCD/OLED) atau flex longgar; garis warna-warni atau hitam yang tetap.
• Separuh skrin gelap / hitam, panel paparan dah gagal separa, atau flex connector tertanggal (biasa lepas jatuh).
• Warna pelik, pink, hijau, atau tint, panel OLED cedera; garis hijau menegak klasik tanda OLED rosak lepas jatuh/tekanan.
• Skrin flicker / kelip-kelip, sambungan paparan tak stabil atau panel mula gagal.
• Sebahagian skrin tak respond touch, satu zon digitizer mati; gambar OK tapi tekan tak jadi di kawasan tu.
• Ghost touch (touch sendiri), digitizer rosak hantar sentuhan palsu; app buka sendiri, taip sendiri.
• Vertical / horizontal lines, display panel (LCD/OLED) or a loose flex; fixed colourful or black lines.
• Half the screen dark / black, the panel has partly failed, or the flex connector has slipped off (common after a drop).
• Odd colours, pink, green, or a tint, an injured OLED panel; a classic vertical green line signals OLED damage after a drop/pressure.
• Screen flickering, an unstable display connection or a panel starting to fail.
• Part of the screen won’t respond to touch, a dead digitizer zone; the image is fine but taps don’t register in that area.
• Ghost touch (touch by itself), a damaged digitizer sends false touches; apps open on their own, it types by itself.
Petua mudah: kalau gambar yang rosak (garis, tint, gelap, kelip), masalahnya paparan/flex. Kalau gambar elok tapi sentuhan yang bermasalah (tak respond atau touch sendiri), masalahnya digitizer. Kedua-duanya pun biasanya diselesaikan dengan tukar skrin, sebab pada kebanyakan phone paparan dan digitizer disatukan dalam satu unit.
A simple tip: if the image is broken (lines, tint, dark, flicker), it’s a display/flex problem. If the image is fine but the touch is faulty (no response or self-tapping), it’s a digitizer problem. Both are usually solved by a screen replacement, because on most phones the display and digitizer are fused into a single unit.
Cuba dulu sebelum repair (quick-check)
Try these first before a repair (quick-check)
Ikut turutan ni, kadang isu kecil boleh selesai tanpa repair, dan langkah ni juga bantu kami kenal pasti punca lebih cepat:
Follow these in order, sometimes a minor issue clears without a repair, and these steps also help us pinpoint the cause faster:
- Restart phone. Force restart untuk buang sebarang glitch paparan sementara. Kalau garis atau ghost touch hilang lepas restart, mungkin cuma software.Restart the phone. Force restart to clear any temporary display glitch. If the lines or ghost touch vanish after restarting, it may just be software.
- Buang screen protector & case. Tempered glass yang pecah, retak halus, atau ada air terperangkap boleh ganggu touch dan buat ghost touch. Cuba tanpa protector dan lap skrin kering.Remove the screen protector & case. A cracked tempered glass, hairline splits, or trapped moisture can interfere with touch and cause ghost touch. Test with no protector and wipe the screen dry.
- Fikir balik: ada jatuh atau kena air baru-baru ni? Kalau ada, punca kemungkinan besar flex connector tertanggal atau panel cedera, ini bukan software, dan biasanya makin teruk. Catat untuk beritahu kami.Recall: any recent drop or water exposure? If so, the cause is most likely a slipped flex connector or an injured panel, this isn’t software, and it usually worsens. Note it to tell us.
- Uji touch di mana yang gagal. Cuba tekan seluruh skrin (buka Notepad, lukis garis). Tentukan sama ada touch gagal di satu zon sahaja atau seluruh skrin, ini beritahu kami sama ada digitizer atau connector.Test where touch fails. Try tapping across the whole screen (open Notes, draw a line). Determine whether touch fails in one zone only or everywhere, this tells us whether it’s the digitizer or the connector.
- Backup data anda SEKARANG. Selagi skrin masih nampak, salin foto & fail penting ke iCloud/Google atau komputer. Garis dan flicker boleh bertukar jadi skrin hitam penuh bila-bila masa.Back up your data NOW. While the screen is still visible, copy important photos & files to iCloud/Google or a computer. Lines and flicker can turn into a full black screen at any time.
⚠️ Don’t wait, it usually gets worse
Garis skrin dan ghost touch jarang kekal sama, ia cenderung merebak. Satu garis boleh jadi banyak, dan akhirnya skrin gelap hitam penuh sampai anda tak boleh akses data langsung. Digitizer yang rosak juga boleh daftar sentuhan rawak sendiri, risiko tersalah taip, dail nombor sendiri, atau tersalah tekan butang bahaya. Backup data dan repair lebih awal, jangan tunggu sampai skrin mati total.
Screen lines and ghost touch rarely stay the same, they tend to spread. One line can become many, and eventually the screen goes fully black until you can’t access your data at all. A failing digitizer can also register random touches on its own, a risk of mistyping, pocket-dialling numbers, or accidentally tapping dangerous buttons. Back up your data and repair sooner rather than later, before the screen dies completely.
Bila kena repair (tukar skrin)
When it needs a repair (screen replacement)
Kalau garis, warna pelik, flicker, zon touch mati, atau ghost touch masih ada selepas restart dan buang protector, hampir pasti panel paparan atau digitizer perlu ditukar. Kadang, jika punca cuma flex connector longgar selepas jatuh ringan, ia boleh dipasang semula tanpa tukar skrin, sebab tu diagnosis dulu penting sebelum bayar apa-apa.
If the lines, odd colours, flicker, dead touch zone, or ghost touch persist after a restart and removing the protector, it’s almost certainly the display panel or digitizer that needs replacing. Occasionally, if the cause is only a loose flex connector after a light drop, it can be reseated without a new screen, which is why a diagnosis first matters before you pay anything.
What we check during diagnosis:
• Panel vs digitizer, kami asingkan sama ada gambar atau sentuhan yang rosak.
• Flex connector, kami buka dan periksa sama ada connector cuma longgar (boleh pasang semula) atau dah cedera.
• Kesan air / kakisan, kalau ada tanda air, kami periksa board sekali supaya isu tak berulang.
• Jenis panel model anda, OLED atau LCD, supaya skrin ganti padan betul dengan phone anda.
• Panel vs digitizer, we isolate whether it’s the image or the touch that’s broken.
• Flex connector, we open up and check whether the connector is merely loose (reseatable) or damaged.
• Water / corrosion signs, if there’s any water evidence, we inspect the board too so the issue doesn’t recur.
• Your model’s panel type, OLED or LCD, so the replacement screen matches your phone correctly.
Skrin yang rosak juga menyukarkan proses reset sebelum jual. Kami huraikan jalan keluarnya dalam panduan reset iPhone sebelum menjual.
A damaged screen also makes it hard to reset a phone before selling it. We cover the way around that in our guide to resetting an iPhone before selling.
Kalau anda merancang menjual telefon itu dan bukan menyimpannya, kami tunjukkan cara mengira sama ada pembaikan skrin kembali modal dalam baiki dahulu atau jual apa adanya.
If you plan to sell the phone rather than keep it, we show how to work out whether a screen repair pays for itself in repair first or sell as-is.
