DM500 loose signal after 10 minutes.

[godboss]

Hi,I have this DM500s colon Tuner BSBE1-702B

I have this problem.

After cooling down for 15-20 minutes the signal is ok and the unit works perfectly; but after some time it

Loose signal after 20-40 minutes when tuned to V(12v) channel.
Loose signal after 5-10 Minutes when tuned to H(18v) channel.
There is no extra heat from any component.

The problem repeats itself after switch off or power plug pull out for 15-20 minutes.

Already checked with diffirent power supply, it is not the problem.

Could it be my lnb?

Seems like a capacitor problem..... but not sure where to start.

What other test should i run to pin point the problem? and help me solve it
THANKS

First thing id check would be the lnb although usually when they go you loose just 1 polarity, if the lnb is ok the check the voltage output when you loose signal that will indicate if you have a stb problem.

Same problem happen with me last winter, it was the LNB's cable detached by wind.
