QUE DISPLAY SAMSUNG 32 POLEGADAS É ESSE 12YFHD320SL4LV0.2

Question

Accepted Answer

Direct answer to the question - The alphanumeric code 12YFHD320SL4LV0.2 is not a retail TV or monitor model. - It identifies a pair of driver scan boards “left” & “right” side-boards and, in many service manuals, the T-CON sub-assembly that work with Samsung’s 32-inch Full-HD LCD panel family. - In practice it is mounted on the LTJ320HN07-L and LTJ320HN07-KHN08 1920 × 1080 LED-back-lit panel, which Samsung used in several 2012-era televisions such as the UE32EH5300W, UE32EH5040W, UE32EH5450, UE32EH5000, UA32EH5000, UA32EH5300 and close derivatives. Key points • Size : 31.5 in advertised as 32 in • Resolution : 1920 × 1080 FHD • Interface : 8-lane LVDS, 60 Hz, Vcom-DAC on board • Back-light : Edge-LED, 3-channel, 105 V typ. • Typical use : Samsung series EH5xxx TVs 2012, a few later re-badged models --- Detailed problem analysis 1. Decoding the string • 12Y – board design family released in 2012 SamsungAmtran joint layout convention • FHD – Full-HD timing 1920 × 1080 • 320 – 32-inch panel class • SL4L – Side board, Left “SL” revision 4, LVDS signalling “LV” • V0.2 – HWPCB revision 0.2 2. Where it sits in the panel electronics The LTJ320HN07-L is an “open-cell” LCD module delivered with an edge-LED back-light, but without the timing controller T-CON; instead, Samsung integrates the T-CON together with the left- and right-gate driver boards on one long PCB that runs across the top of the glass. The service part number for that PCB set is what you see on the sticker: 12YFHD320SL4LV0.2 12YFHD320SR4LV0.2 left & right halves. 3. Service documentation cross-references • Samsung parts database lists BN96-21452A or –21452B as “BOARD P-TCON; 12YFHD320SL4LV0.2” • Same board appears in UE32EH5300W service manual, section “Panel Parts List → FHD 32” 4. Electrical specification excerpt from panel datasheet – Logic supply: 12 V ±0.3 V, 0.6 A typ. – LED driver input: 90-140 V, 160 mA three series strings – LVDS mapping: JEIDA-24bit, 8 lanes, clock 74.25 MHz 5. Mechanical interchangeability Samsung sourced secondary 32″ FHD cells from CSOT V320BJ6-PE1 and AUO T320HVF05.x. Those use different T-CONs names start with 32Txx or 13Yxxx. Hence 12YFHD320SL4LV0.2 is only compatible with LTJ320HN0x panels; mixing boards will result in a dark or garbled screen. --- Current information and trends - 32″ TV panels have largely shifted to open-cell + external T-CON layouts and often use eDP instead of LVDS. - Samsung Display stopped in-house production of smallmedium a-Si TFT-LCD in 2020; panels of this class are now typically supplied by BOE, CSOT or HKC. - For repairs, the availability of LTJ320HN07-L and its 12YFHD… boards is declining; refurbished pulls and NOS stock are the main sources. --- Supporting explanations and details Example workflow when this board fails: 1 TV turns on → back-light lit → no video or vertical coloured bands. 2 Measure 12 V on the T-CON supply fuse → OK. 3 Oscilloscope on LVDS clock lines shows activity, yet panel blank → suspect 12YFHD320SL4LV0.2. Replacement requires removing the metal frame bezel, unclipping the side PCBs and transferring COF ribbons carefully to avoid glass damage. --- Ethical and legal aspects - Samsung firmware and service manuals are copyrighted; distribute only excerpts necessary for repair. - Ensure ESD protection when handling bare LCD glass—latent damage is a frequent cause of repeat failures. - Counterfeit boards labelled “12YFHD320…” appear on online marketplaces; always verify supplier reputation. --- Practical guidelines • Always order the exact revision 0.2, 0.3, etc.. • Match the panel suffix -L ‑H printed on the glass; mixed versions can shut down due to Vcom mismatch. • Perform a panel ID read-out via I²C service jig before replacing parts to avoid mis-identification. • After replacement, run the built-in aging pattern white-black-colour cycle for ≥30 min to equalise Vcom. --- Possible disclaimers or additional notes - Some UE32EH5300 units were shipped with AUO T320HVN02.1 panels; in that case the correct T-CON part is 13YFHD32…—not interchangeable. - If glass is cracked, replacing only the board will not restore functionality; entire panel must be swapped. --- Suggestions for further research - Compare Samsungs’ 12Y-series board schematics with later 14YeDP designs to study the migration from LVDS to eDP. - Investigate gate-driver-on-array GOA failures on LTJ320HNxx panels; common in field returns. - Explore aftermarket adaptive boards that allow cross-branding of 32″ FHD open-cells with generic T-CONs RTD-based. --- Brief summary The code 12YFHD320SL4LV0.2 belongs to the driverT-CON board set used on Samsung’s 32-inch Full-HD LCD module LTJ320HN07-L and close variants. That panel, driven via 8-lane LVDS, equipped many 2012-era Samsung EH5xxx televisions such as UE32EH5300W and UE32EH5040W. When you encounter this code you are looking at an internal service part, not a consumer model; replacing or diagnosing it requires matching the exact panel family and PCB revision.
