![]() Samsung LNXXA550P3 series with bad caps on the main board, TV makes squealing static sound through speakers, cycle on and off, etc.
Temporary solder in 100uF 10V low ESR cap in parallel with C102 to see if it solves the problem, but make sure the power supply caps are OK first. KEMET Polymer Tantalum caps can be used. |

![]() I have a Samsung ln52a550p3fxza, replaced the bad caps about a year ago, now have a strange issue when first powering up the tv, there appears to be off colored distortion through out the screen, then periods of green pixalition on black areas, after a period of time picture returns to normal, scanned through the forums, checked for other reports of this issue without any luck. I suspect T-con board but would like your opinions, Thanks
