Tenma 72-14525 no signal

Question

Hi everyone, 
 On my Tenma oscilloscope, i have no trace for both channel. 
 The probe works fine, but nothing on the screen 
 Can someone help me? 
 Where can i find the lastest firmware for the oscilloscope 72-14525 
 
 Contact technical support of Farnell, he can't help me... 
 
 Thanks, 
 
 Philippe

Most Tenma products are manufactured by another company. If I have a problem, I run a google search to see if I can find the actual manufacturer for help. In your case, try UNI-T (Unitech), product series UPO2000E, particularly the UPO2102E. Look under "Obsolete Digital Oscilloscopes". I'm not sure if they are the actual manufacturer, but they have a support sight.
