'Easy Touch' ETL071-32HD

[Turnip]

    Hello Folks,

    One from our Chinese brothers, I think, where after working well for 10 minutes, it cuts totally, but with the Led still showing green. On re-applying mains, it lasts 30 seconds.

    Suspect Power supply problems, as although - Shenzhen Chuangeng Huike CN88-320P-5S24125 - version 2.2 is a tidy unit, but it keeps it's caps under heat sinks, pehaps for safety. No cap exhibits a domed top, but I'm naturally suspicious.

   Note that a web site is printed on the PCB - WWW.cheng.com  -  but suspect little help would be forthcoming.

    Any ideas - Chris.

Hi Folks,

   Set now OK. After dismantling to inspect set and photograph panels, on re-assembly set worked without fault. Suspect perhaps Power to Invertor plugs/sockets a bit iffy.
