Hi,No schematics are available to my knowledge.
I have recently repaired the motherboard with problem of No operation except power led blinking when operating with remote or panel switches.

Just heated the metal shielded box which has the micro processor ICs.

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.

Sorry, but I am not seeing where to download it on that page Without it taking me to another website or installing 3rd party software. Where on the page can I click to download and just get the manual?

Another confirmed bad caps on SAMSUNG MAIN BOARD for LNXXA55X series.

Please note that the BAR marking on those two TANTALUM caps = POSITIVE pin.

Default Re: LCD TV and Monitor basic troubleshooting guides

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
