hi everyone,
(hope i am in the right section with that unsolved issue)
the issue : Fixing a faulty Remote Control.
i have a remote control of a DVB-T (Hyundai HY-2806), that suddenly had stopped functioning.
the right steps to check it (as for my opinion) :
1. Replace to Remote batteries for a new pairs - still not functioning.
2. i brought a same remote model from someone, tried it , and its work perfect
conclustion: - the DVB-T is ok, the Remote is faulty.
3. remote's LED output check:
put the remote in front of a camera (The LED towards the camera)
now press some buttons on the remote,
if on the camera we see the remote's LED lights on and off, so the remote is somehow functioning.
if no lights seen on the camera, so the remote is completely dead - this is my case.
4. i openned the remote and solder again all the solders on the PCB ,
put back all the parts, and tried again - still nothing.
5. now i am on a dead end:
on the PCB, only 3 chips/parts :
a. the LED
b. a chip called HS 455E (is it a kind of oscillator?)
**broken link removed** **broken link removed**
c. the "Brain" or CPU, dont know how to name it , and it is hiding under a black , inflexiable big dot.
is there way to know what under it?
any suggestions of what else can be done?
thanks,
itai
