Hi,
I have a Hitachi c28wf560n, Vestel 11AK45 chassis. After around 5 minutes of use, the picture dissapears, but the sound remains OK. It recovers if I switch it off for some time.

1. I have the schematic/service manual downloaded from this website, but the resolution is too low so I can't read the circuit designators or component values of the schematic. Can anyone provide a better schematic?

2. A visual inspection of the RGB amplifier PCB on the rear of the tube (marked 11TP45E-3) suggests damage to R956. I removed and measured it at 10 Ohms, but can't read the component markings so don't know what it should be. Anyone know?

3. Any other suggestions for this fault on 11AK45?

Thanks!!
Martin.
