Television and Home Theater

I own a WS-65311 with low hours on it that I purchased new from Mitsubishi maybe 4 years ago. About 2 months ago the picture started to blink on and off between black screen and the picture. Does not matter which input it is on. I left it unplugged for about a month and it ran good for about 2 months but now it is back again and much worse. Now it blinks very rapidly about 1-2 time per second. I need help from the experts!! I was going to take this to my new house and find an external HD tuner for it, if they still make them, but now I might have to leave it behind. Any ideas?

hello i an new to the community and i have been having problems getting this to post. i have a convergence problem on the red only. i have been looking all over the internet for help. i have found some if someone could give me some tips. i have never repaired a tv before so please excuse the dumbness but i am technically inclined. i was trying to test pico fuses, resistors etc. i found a post some where that i needed 22v pos and 22v neg on pin 10 on ic's. well i dont know if i was testing it correctly but i had 56v. i would greatly appreciate the help if someone could give some.

Hi, I have a RCA 52" T.V model no. D52w14. When we are watching t.v through dish we only get sound coming out of the left front speaker.When we first set up everything we was getting surround sound but for some reason we don't anymore. We also have a philips surround sound dvd player with 5 speakers,when we watch dvd's we get full surround sound with no issues at all but when we switch back to t.v it just plays sound through the left front channel.We are not sure if its a setting with the t.v or the dvd player? can anybody help us out what the problem is?.

Thanks.
