TDS210

 

Hi All
Anyone know what the correct voltage is at the input of L6 on the Power Supply. Its the supply circuit for the display CCFL. I'm getting -4.6v.
My display is a dull shade of orange with no detail. A new display did not fix it. The output CCFL voltage is reading 768v pk-pk. Manual says is should be 1270v pk-pk. The other power supply voltages are correct.
 

On my TDS220 I changed the backlight lamp to a LED strip.
