Post by: t1412 on April 29, 2016,21:14:14

hi fella's got toshiba tv got no model number as i forgot to write it down, it's got 17pw25-4 psu with a 17mb62 2.6 mainboard installed, the original fault was no standby light lit voltages were all over the place, i've changed the psu, with now have stand by light, voltages are steady now, but now
the standby light is flashing green, there's no 24v to the inverters , could this be a firmware fault, if so does any body have one thanks for your time

regards

Hi Shaun ,if you have changed the PSU board you have to make sure its the right one . There is something about the voltages . One board has 5v and the other has 3.3v.  Remember seeing a post about the first two numbers being 20 or 23 that indicates which board you need to replace it with
