Hi
I am trying to repair this tv for my neighbour .
The red standby light is on.
I switch the tv on and the standby light flashes blue and backlights flash for a couple of seconds and then turn off.
Then the standby light justs cycles between red and blue.
The power supply is a vestel 17PW26-5 v.3.
The main board is a 17MB65-2.
I have replaced the inveter board and it does the same. Ive disconnected the inverter board but still the same.
On the power supply the white connecter top right hand corner I get the following voltages
Starting at the top with column on the left hand side
readings are
standby voltages /on voltages
0 / 0
7.86 / 8.97
2.57 /0

I have checked some of the caps on a meter and they are fine theres no leaks
Any pointers would be really appreciated -
