Vestel 17PW16-2 troubleshooting

Re: Vestel 17PW16-2 troubleshooting

On your picture of IC825 it's hard to see where the tracks are isolated from each other where they go under the IC, (as I think you said the original device wasn't surface mounted). Just make sure there are no shorts between pins, does it test OK on diode test? There is no ground - top pin is anode, middle pin & tab are cathode.

Sorry, I was merely (uninformed) stating there is continuity in diode mode between the top tab/pin (pin 4) and centre stubby pin 2. The original didn't have a connection and it's easy enough to remove so I might do that. I only typed ground in error.

Does this new picture help show that the centre pin trace appears to join up with tab?

Just make sure it reads correctly on diode test, left pin to tab/middle pin (your latest pic). Also that these pins are not shorted to your circuit ground.
