E89382 Hannstar J Mv-4 94v-0 Boardview

This appears to be a partial identifier for a printed circuit board (PCB) or a flat panel display control board, combining several standard markings:

• E89382 – Typically a UL recognition file number (Underwriters Laboratories). For example, UL File E89382 is known to be associated with HannStar Display Corporation for PCBs used in LCD monitors/TVs.
• Hannstar – HannStar Display Corp., a Taiwanese manufacturer of LCD panels and display modules.
• J Mv-4 – Likely a board model/revision code (e.g., "J" revision, "Mv-4" = Motherboard/Video version 4).
• 94v-0 – UL flammability rating for the PCB material (means vertical burn test passes, burns stop within 10 seconds, no dripping).

What you likely have:

• A LCD controller board (or T-con board / power+LED driver combo) from a HannStar display.
• The Boardview file is a CAD-like layout showing component locations, test points, resistor/capacitor IDs, and net names — used for repair/schematic tracing.

To find the exact Boardview file (.brd, .cad, .fz, etc.): E89382 Hannstar J Mv-4 94v-0 Boardview

1. Search using the full string E89382 Hannstar J Mv-4 in repair forums (Badcaps.net, Elektrotanya, LCD repair groups).
2. Check board itself for a longer model number (e.g., HannStar J MV-4 94V-0 followed by a date/version).
3. Look for common HannStar board part numbers like JTxxx, MV-4, or numbers starting with HK.

If you can provide a photo or more characters from the silkscreen (e.g., HannStar J MV-4 REV:xx), I can help narrow down the exact Boardview file.

Despite your best efforts, the exact Boardview for revision "MV-4" might be elusive. Do not panic. This appears to be a partial identifier for

2. Functional Role of the MV-4 Board

The E89382 MV-4 is rarely a main motherboard (no CPU or RAM slots). Instead, it serves as:

• LCD Panel Timing Controller (TCON) Board : Converts LVDS signals from the main board into signals that drive the gate and source drivers of the LCD.
• Power-Logic Combo Board : Integrates a DC-DC converter (generating VGH, VGL, VCOM) with a small microcontroller for button/LED control.
• Input Interface Board : Provides VGA, DVI, or HDMI inputs, plus audio input jacks, feeding into a scalar chip.

Common devices containing this board:

• Hannstar 17"–22" LCD monitors (e.g., HSG series).
• Acer/HP/Lenovo all-in-one PCs from 2012–2016 (used as an internal display driver).
• Portable DVD players with LCD screens.

The Ultimate Guide to the E89382 Hannstar J Mv-4 94v-0 Boardview: Schematics, Repair, and Pinouts

In the world of electronics repair, particularly in LCD monitor and TV main board troubleshooting, few things are as critical as the Boardview file. For technicians dealing with power supply failures, no-signal issues, or dead-silent units, finding the correct reference data for a specific board is half the battle. One such board that frequently appears on repair benches is the E89382 Hannstar J Mv-4 94v-0.
