A new episode of consumer show Watchdog aired in the UK yesterday evening, the program taking a hard look at the PS3's performance issues.

Responding to the contents of the show, Sony UK exec Ray Maguire has noted with concern the leanings of the program - claiming it misrepresents the quality of the console - and the maker's consumer support.

GI.biz has reportedly duly received a six page-letter, explaining the firm's position.

"We entirely refute the suggestion that consoles have an inherent defect or other design issue which is akin to any warranty issue experienced by another console manufacturer," Maguire rails in the letter.

"SCEUK has sold 2.5 million consoles in the UK since March 2007 and stands by the quality of its products. Clearly the allegations you propose to air in your program might have the potential to adversely effect Sony Computer Entertainment's reputation for supplying high quality products and customer service and we take very seriously any that can impact the public's or our customers' confidence in those products."
