Dough Spectrum Limited Warranty

Dough guarantees that the Dough Spectrum (or Eve Spectrum - as our previous name) products that you have purchased are free from defects in materials or workmanship under normal use during the Limited Warranty Period. In case an issue arises, Dough’s agents will attempt to correct any minor issues that might be causing the product failure. If the technical service and support representative is unable to resolve the issue, Dough will, at its option: (i) provide replacement parts necessary to repair the product; (ii) repair the product or replace it with a comparable product; or (iii) refund the amount you paid for the product, less depreciation, upon its return. Replacement parts and products will be new or serviceably used, comparable in function and performance to the original part or product. 


This warranty applies for a period of three (3) years from the date the product was first purchased by an end-customer. 

Your sales receipt, showing the date of purchase, is the proof of your purchase date. You may be required to present the proof of purchase as a condition of receiving warranty service. In case of missing proof of purchase, the Limited Warranty Period is considered to have started from the date of manufacturing indicated on the product or from the serial number of the product, and will end after three (3) years. For products sold through the Dough web store, the date of delivery counts as the start of the Limited Warranty Period. 

The Limited Warranty Period for the power adapter is one (1) year from date of purchase. Parts and products replaced under warranty assume the remaining original warranty, or ninety (90) days after they are shipped to you, whichever is longer. 


If you have a defect within fourteen (14) days from the date of purchase (the DOA Period), the product is considered Dead On Arrival (DOA). Dough will replace the DOA unit with a brand-new replacement and will cover the freight charges both ways. Your defective product must be returned completely in the original box with all the accessories included. Dough has the right to claim the costs for any missing parts or any other customer induced damage. For products sold through the Dough web store, the date of delivery counts as the start of the DOA Period. 


Displays are made of pixels. Each pixel is made up of a red, green, and blue sub-pixel, and each sub-pixel is driven by an individual transistor. If a transistor becomes defective, the corresponding dot may be permanently lit (bright) or may not light (dark). Independently of the brand and the manufacturer, it is common for one or more sub-pixels to become fixed in an unchanging state. 

Panel manufacturers set limits as to how many defective dots (or sub-pixels) are deemed to be acceptable on any LCD panel. Dough’s manufacturer warranty covers any defects that exceed the following specifications: 

  • No Bright Dot Defects. (A full pixel or sub-pixel that remains permanently lit, resulting in a white or colored dot on a black background.) 
  • No more than 5 Dark Dot Defects. (These appear as a full pixel or sub pixel that remains permanently unlit, resulting in a black or colored dot on a white background.) 

A sub-pixel affected for less than 50% of its surface not counted as a Bright Dot Defect or Dark Dot Defect. Similarly, a dot darker than 50% brightness is not defined as Bright Dot Defect and a dot brighter than 50% brightness is not defined as Dark Dot Defect. 


Damage caused by static (non-moving) images displayed for lengthy periods of time (also referred to as image burn-in) is covered for a period of two (2) years from the date the product was first purchased by an end-customer.
