How PanelView Plus 6 12"/15" units actually fail
Most units we receive fail in one of a handful of well-understood ways. Here is what each fault looks like from the machine, what is happening electronically, and what we do about it at the bench.
Large-format backlight failure
- What you see
- A dark or unevenly lit screen — sometimes bright at one edge and dim across the rest.
- Why it happens
- Larger panels use longer backlight assemblies with more of the circuitry that drives them, so they have proportionally more to fail and are more prone to visibly uneven illumination as elements age at different rates.
- What we do
- The backlight assembly and drive circuitry are repaired or replaced, then illumination uniformity is checked across the full panel area.
Touch digitizer failure on large panels
- What you see
- Dead zones, drift, or ghost touches — often worst in the middle of a wide screen.
- Why it happens
- A larger touch surface means longer conductive traces and greater mechanical flex, and the centre of a big panel deflects most when pressed. Both accelerate wear relative to a small terminal.
- What we do
- The digitizer is replaced and calibration verified across the entire surface, with particular attention to centre-screen accuracy.
Power supply aging under higher load
- What you see
- No power, resets under load, or a unit that will not boot reliably when warm.
- Why it happens
- A bigger display draws more current, so the supply in a large-format terminal runs hotter and works harder than in a small one. Capacitor aging therefore tends to show up sooner and more severely.
- What we do
- The capacitor set is replaced and all rails verified under genuine load, followed by repeated cold-boot testing and a warm soak.
Large-format terminals are the most expensive HMIs to replace and among the most disruptive, because the panel cutout is specific to the unit. A replacement of a different size frequently means modifying or replacing the enclosure door itself — which is why repair economics on the 1250 and 1500 are even stronger than on the smaller models.
What happens on the bench
The same sequence on every 5-stage repair, so nothing gets skipped because a fault looked obvious.
- 1
Intake and symptom replication
We log the unit against your RMA and power it on the bench to reproduce what you reported. A terminal that boots fine for us is worth knowing about early — intermittent faults are usually thermal or a marginal power rail, and both change what we test next.
- 2
Rail and power-supply measurement
The internal supply is measured under load, not just at idle. Aging electrolytic capacitors lose capacitance and gain equivalent series resistance, so a rail can read correct on a meter and still collapse the moment the backlight or processor draws current. Ripple is checked on a scope rather than assumed.
- 3
Display, backlight and touch isolation
A dark screen is separated into three different repairs: a failed backlight (image still faintly visible under a bright light), a failed inverter or LED driver, or a genuinely failed LCD. Touch faults are isolated to the digitizer, its flex tail, or the controller before anything is replaced.
- 4
Board-level repair
We replace the failed components — capacitors, backlight assembly, digitizer, driver circuitry — rather than swapping whole boards. Where capacitor aging is found on a supply, the set is replaced, because the ones that have not failed yet have lived the same thermal life as the one that did.
- 5
Functional test and burn-in
The terminal is booted repeatedly from cold, the touch grid is calibrated and checked corner to corner, communication ports are exercised, and the unit is left running to catch faults that only appear once it is warm.
Check these before you ship
Some of these will tell you the unit is fine and the fault is elsewhere. We would rather you find that out now than pay to ship a good unit.
- □Confirm the supply feeding the terminal is actually delivering its rated voltage under load — a failing panel supply mimics a dead HMI exactly.
- □Shine a bright light at an angle across a dark screen. If you can make out the application faintly, the LCD is alive and you have a backlight fault, which is a cheaper and faster repair.
- □If the unit boots but the touch is wrong only in one region, note where. Localized dead zones point at digitizer wear; whole-screen drift more often points at the controller.
- □Note the exact text of any boot or fatal error. The code narrows the fault far faster than "it will not start".
- □Back up your runtime application if you have a copy — we preserve what is on the unit, but a backup is cheap insurance on any repair.
Repair or replace?
Operator terminals are the clearest repair-over-replace case in a plant. Much of the installed base is discontinued with no drop-in successor, so replacing means specifying new hardware, re-developing or converting the application, re-testing it against live machinery, and retraining operators on a screen that behaves differently. The repaired terminal drops back into the same panel cutout running the same application. Even where a successor exists, the migration engineering usually costs several times the repair.
What to ship
- ▸The terminal only — well padded; these are heavy enough to break loose in a thin box

Frequently asked questions
Why is the large-format price higher?
The 12.1" and 15" digitizers, backlights, and LCD assemblies cost several times what the small-format parts do. The flat price still lands far below the $3,000+ these terminals bring on the used market.
Is repair worth it versus hunting a used unit?
A used 15" PVP6 typically runs $700–$1,200 with unknown history and no warranty — and your team still has to load and prove the application. Repairing your own terminal keeps the program in place and carries a 24-month warranty.
