DM500S Clone LED green only -WILL FLASH

[topekabill]

I have DM500S clone that will not boot. Checked TR72; looks good voltage wise. Not getting signal from processor to turn on. Unit can be flashed via Dreamup and null cable. Flash says successful. Only green led will light, no red, responds with blinking from remote but will not change. No video output; no standby.

Most users with green led locked problem cant flash, I can flash but is locked up somehow. I have made Jtag for this but have not Jtagged. I felt if it was accepting images correctly the boot should be good.

Need help!

Thanks

Check power supply capacitors prone to failure and in laymans terms the psu has not the strength to run the box correctly.Try using a cheap multivolt power suppy poundland, chinese bazzar set to correct polarity and voltage and I feel sure that could be your problem.(the capacitors are very poor quality and they tend to blow indication would be top of capacitor domed)Repair of the exsisting psu is easy but you need to split the glued joint and fit and solder in place new capacitor ,trust this helps.

Ps only use the multivolt for testing as it is not of sufficent Amperage to run the box for any length of time you need a 2amp psu to runbox correctly.
