Hello,
I'm looking at a JVC 43" Vestel made TV. It has a VERY intermittent problem with no backlight but has display, sound etc. when switching on. I've tested the backlight circuit, all ok.
I've fixed so many of these sort of TVs I thought I had this problem under my belt but this one is different.
Here's a pic of the hot side of the psu, there are two unknown (to me) components marked sr2 and sr5, can anyone identify what they are? The top one (sr5) is shorted, the bottom one isnt. I also attach the psu schematic although that doesn't really tell me what they do apart from 'SMD Pingood'. What does that mean?
Any help is appreciated.
