Toshoba 37rv635d on / off button pcb

[alerton]

Hi, While im waiting for parts (led strips) from china for my L401333db i have got hold of another Toshiba TV (37rv635d). This one is working fine but needs a replacement on / off switch as the existing one has been botched to be on all the time because it was arcing internally. There are no end of these switches on ebay so im guessing they are a common fault but whoever botched it previously has also damaged the plastic parts of the switch so i have been looking for a whole assembly with the pcb and plastics. my question is are all these V28A000712A1 PCBs interchangeable? there seems to be 4 or 5 versions but from what i can see they are all identical and the same TV model seems to have various versions listed as suitable. Theres no components on the pcb as such just connectors and the switch so i cant really see what the difference could be but im sure some of you experts will have a better idea than me. Thanks guys.

second is same as my board seems do be R2 with damaged plastics on the end of the switch first is R4 with good plastics on the end of the switch.

in my tv it has had an extra piece stuck on the end of the switch actuator to compensate for the damaged switch on the pcb and whilst it does seem to have been done quite cleverly and it works if im changing the switch anyway id rather just change the whole assembly and have it all back to factory standard.

OK just an update, the R4 board i ordered arrived today and yes it is directly interchangeable with the R2 board. Fitted and working fine. Firmware also updated to the latest. I have to admit though, having seen the switch actuator (also replaced) i can see why the old one was damaged, it really is a pretty 'mickey mouse' arrangement; i would have thought Toshiba could have found a way to make everything line up better and work more 'positively' but i guess its down to cost and using the same components in alot of different models etc. Anyway.. its working fine and for a total cost of £38 i dont think its too bad, the picture is nice and has all the connections the lad could ever need.
