Question about Toshiba 42HP66 42 in. LCD Television
We read these posts, gathered information, took the back panel apart on my 42HP66 Toshiba Plasma and identified the YSUS and the ZSUS boards. It appears that it *could* be the ZSUS board since it is making a high pitched noise (you have to put your ear up to it to hear it). Sounds like it could be fried. Any suggestions? Is there a way to actually test these boards? Any special tools needed?
Thanks in advance!!
To test the zsus board check for a low resistance on the fuse to ground. sadly if the zsus is bad, the ysus and one or both of the driver boards is probably also bad. best to change all at once as a defective one can tacke out the others.
