Hi.
I am having trouble with som hotel CRT's 17HT5404, they are turning off after 2-5 min, and i can see and hear a flikkering noice both on the screen and from the chassis. Som messurments are a little high, but the can't seem to pinponit it down to what is cousing it, the 95V is 98V, the 13V is 14V, but the biggest diffrent from the schematics is the voltage around the optocoupler, where the Voltage are much higher on both sides.
Anyone out there that can help ??
