Television and Home Theater

I have a ws-55515. When i try to use the device menu on the tv or remote the tv functions freeze up. After a minute it resets the tv. Is there any one that has a clue?? My email is [email protected]

I am new to the community and after reading some of the posted responses on this problem, I feel I am ready to tackle.  Question:  Is there a way to troubleshoot the IC boards prior to diving in and replacing them?  Should I replace both (from what I have read) or just the one that is defective?   How can I determine which one is the culprit?  I am mechanically inclined, but is there a manual that will help me with this repair?

i have a sony SR252N63K & it blinks 2 times.what section do i have to fix or what would be the common deffective components i have to check?i have checked all the diodes & transistors on power supply but its all good.there's an ic MCZ30001DB & EK1135 & a module on power supply but i dont know if it is the problem. can you help me how can i fix it?thanks!
