That hard starting points to issues that must be fixed before the failure causes other board failures. In the USA you can use www.samsung.com to set up a service call.
I have this older Tv, paid quite a bit for it, and now it has been messing up. Problem.. clicking and not turnung on. when it turns on after much clicking it has dots, after i turn it back off and wait again for it to come on it will clear up at times. sometimes it takes forever to get it working, but once it is, it works great. what can be done? I love this tv...and really want to fix it..can this be done?
