Hi Ben,

Your error codes point to a failed SC board. Try this to verify:

Remove connectors between SU/SD and SC boards. Remove all screws securing SU/SD and fold the boards away from the SC. DO NOT remove the flat brown leads to the display or you'll spend half a day getting them back correctly. Locate socket SC20 on SC and short out the 2 pins.

Switch the TV on. If the set powers on to a solid green standby light, SC is OK and a green LED should light up on the SC. If you still get code 7, then the SC is knackered. It can cause codes 4, 5, 6, 7 and 10 and not necessarily from shorted FETs &/or diodes. I assume you've checked all of them on the SC.

My only concern is code 8 which is a SS board fault, but it might be normal with SC20 disconnected. Of course, if code 7 is cleared in the above test, then you have a faulty SU &/or SD, but we'll cross that bridge when we come to it. See how you go with that for starters.       -      Bruce

Hi Bruce,
Managed to get the TV fixed, it was down to faulty SU, SD boards. Managed to source cheap replacements from eBay. All good now. Thanks for your help.

That's bonza, Ben. Hope you did the screws on the SC board.

bgunn:
Yep, sorted the screws too!
