Dreambox 500s tuner (no signal) fix HD Video

[ultrahd]

I measured the voltages you are ok, I replaced the q72, but I did not signal the same thing can be?

[PetrosAthensGr]

@ultrahd please check with another power supply, could be faulty, or check your receiver with another dish / installation.

[ultrahd]

I measured the tuner and seems to be ok, I also replaced the chip as in the video but nothing has changed. Can I do something else? thanks

i have try to find that componet on is PCB but no......

@MrUribox You will not find, DM5620 have a different pcb layout. Try to find the schematic diagram for the above model, and send it to me. i will try to help you as well.

Такая же проблемма и с моим произошла. Снял транзистор с картоприемника и заменил сгоревший.

gostei do video

[ultrahd]

I say channel not found "I follow this guide?

[PetrosAthensGr]

@ultrahd yes you can check. it might be the q72 defective. first be sure that your satellite equipment its ok

[dirtdigller]

Hello,

Great video...i have a Dreambox 500+ but i can"t locate de Q72. do you know where it is?..it looks like it hase a different layout....Thank you verry much

[PetrosAthensGr]

@dirtdigller Thanks, dm500+ has a different layout, sorry i can't help you..

[tanitrendyboy]

q72 should be FDN352AP? i've changed the transistor and still doesnt work.. it says '' service could not be found'''what to do

[PetrosAthensGr]

@tanitrendyboy Yes. Could you please check U70 LT1930, maybe is defective, also 1040 (ic 40) check if is very hot or normal. Regards

[PetrosAthensGr]

@tanitrendyboy Check also C4 4.7 uF Tantalum electrolytes (in tuner pcb)

[niggi109]

Hello, thanks for the tutorial, very useful.

In my dm500 some channels on Hotbird can not be open. It shows "Switch service not found", but some other channels are ok. Is this still the case to change Q72?

Thanks in advance for your answer.

[PetrosAthensGr]

@niggi109 hello. are the problem in vertical or horizontal polarity? if is on Horizontal check and replace P-chanell MOSFET Q72 , NDS352APCT or IRLML2803. Regards

[niggi109]

@PetrosAthensGr Hello. The problem is only in horizontal. Should I change only the tuner?

Thanks for your help. 

[PetrosAthensGr]

@niggi109 check and replace P-chanell MOSFET Q72 , NDS352APCT or IRLML2803. Regards

[tanitrendyboy]

where to find the transistor Q72? does it easy to find?

[PetrosAthensGr]

@tanitrendyboy Depents of your country. You can find easy on internet and maybe on e-bay. Regards

[ramnik1964]

what wiil happen if i remove Q72?

[PetrosAthensGr]

@ramnik1964 If you remove it you have to bridge it. The box will working but dont have any protection anymore for short circuit. SO it's not recommended to do that, unless you want your box to be on fire!

[kwelmma]

does this fix the problem for the signal to your TV (only green light is on)

[PetrosAthensGr]

@kwelmma No, in this case you have to flash your box again with the firmware again using a serial port and a null modem D9 cable. First check the scart and the rca connections, cables and the TV input, to be sure that this is not came from a bad connection

[naofal2008]

umm what about the F70 transistor you change it ;-) :D

[PetrosAthensGr]

@naofal2008 The F70 is not a transistor, is a fuse. if you measure it and found burned, you should change it.
