Vista 20P will work fine for several weeks and then suddenly go into alarm without a fault in any zone. No log of fault. Changing main board did not fix.

SOURCE: LinkedIn tanks at log in w/ Windows Vista, fine with prior operating systems

I found a solution for *my* problem, by shrinking the MTU in my router.

I have two Vista PCs at home that can't access LinkedIn's sign-in page.

I was suspicious that several browsers seemed to be having a problem, which made me think it was either a virus middleman in the network code, or a router problem. I eliminated the virus possibility by replicating the problem on another PC.

By changing the MTU on my home router from Auto to 1452, I got the signup page to appear.

It appears that Windows Vista's new TCP stack does some advanced segment and window sizing and that didn't work with my Linksys RV042 router's Auto MTU setting. I'm not 100% sure what it is about LinkedIn that caused a packet of just the wrong size, but this is the second time I had to tweak this router to work with Vista. First I needed a firmware upgrade to get some traffic flows to work at all, and now this MTU change.

I do know I've had to change MTU settings in the past to work with encapsulation protocols like PPPoE, but I haven't had to change the MTU setting for quite some time...

Maybe this clue will help someone else...

Turn off zone 2 then turn your receiver on the main zone on Radio, tune in a station and check for audio. Post a comment and let me know if audio works that way. If you don't have any audio, list your other equipment makes and models as well as how they are interconnected to your receiver (cable type) and I will help you troubleshoot

Check the keypad wiring. it sounds like you have wires crossed, a bad keypad, or possibly a keypad address issue.

Check for buldging caps. Burn marks and discolorations around the components. I have found newer caps are failing around the bottom instead of bursting the tops. Check the voltages out to the mainboard to make sure they are where they should be. Another thing to do is reflow the solder on fets, transformers anything that looks broken, you can use a jewlers glass to check for these cracks.

SOURCE: main circuit board faulty

SE is 'sensor error' This could be anything from a loose wire to a faulty Hall sensor or even a main board failure......You probably need an LG technician. Your machine sounds like it's worth repairing.. Get quotes.........Good luck...Nomess
