I have a Humax HDR Fox T2 which has performed very well for 10+ years. When feeding into a new Panasonic TV the HDMI handshake fails and produces the dreaded “green screen”. On the old TV, also a Panasonic, there was very occasionally a very short green-screen flash but it then connects and works perfectly.
I have tried replacing the T2 with an Aura but get intermittent but very severe pixelation on the SFN of COM7. I have had the problem with two copies of the Aura. The T2 never showed this problem, or does four other TV’s fed from the same aerial system at the same time. Because the Aura is not fit for purpose, at least my purpose, I have had to buy a Manhattan T3-R. The Manhattan does exactly what it is designed to do and does it well - but unfortunately I prefer the T2.
Looking at the T2 PCB the HDMI transmission interface is done by two quad flat package IC’s (DA9984A/15/13 and DA19977A/15C129). The DA19977A is an HDI receiver with HDCP, while the DA9984A is the receiver.
Presumably the problem lies with these chips or the associated clock generators. The data sheet for the DA19977A refers to software drivers and so presumably these later versions of the Humax software has incorporated these.
Does any reader know if anyone has had the “green-screen” issue fixed by a hardware repair, such as the replacement of these chips? Alternatively are replacement main boards available from Humax?
