JVC LT-42E488 Not detecting HDMI inputs after repair

[Drexter]

Hi guys,

Long story short, my Tv, stopped tunning cable frequencies, I started to diagnose the tv, and found out there were 2 caps completely dried up, very high esr, one was a 22uf, and the other one was inside the tunner a 10uf/16 volts one, after replacing them. got back cable frequencies . Bad thing is no l don't have now HDMI. It seemed blocked, so I made a litte digging on the subject and found out that it may be due to a light sensor disabeling the hdmi ports for copy protection of some sort.

I tried accesing the service menu without finding any reset or factory default, also other kinds of solutions for other JVC models. None of them worked.

Does anyone has any experience with this particular model?, I cant find a service manual for this particular one. Only for other Lt models, witch have completely different service menu and functions.

Any help is welcome, Im very frustrated, ran out of ideas.

Thanks!!

There is a firmware update for this model, but I don't know if it will fix the problem. Download from here: http://www.jvc.ca/downloads/update_p...re_LT-E_en.htm
