TOSHIBA 40L1333B NO PICTURE BUT GOT SOUND

When I got to where you are, I removed the connecting board then supplied 24v to each LED strip individually and this revealed the problem. Strips A and B did not light, strips C,D and E did and went brighter as I upped the voltage to 30v. A visual inspection revealed black burn marks on one of the individual LEDs on strip A. I must get round to finishing the job. Good luck, Henry.

Thanks Henry, will have a go and see what happens. Read the strips are glued in and break if you try to take them out
grandad h:
Kenny. These strips use double sided tape and are marked ABCD and E. I removed the top joining panel and on panel A, I soldered two wires to where the plug is mounted and applied 20v. As I said, check the five of them and replace the strips that do not light. Henry.

How did you get on with the Toshiba eventually Henry.

Am just going to wait till I get a working TV then I can swop the boards and check them before I start with the stripes on the screen . Thanks for your help anyway .
