The fault lies with faulty capacitors on the power board,just had mine repaired.
the power board is easy to get to,just remove the back panel and its directly in
the middle.
The faulty capacitors are quite obvious as they start to bulge at the top
I sent mine to a company in Watford called gtvwatford 55 pounds for
the repair and now as good as new. pretty common with this lcd panel
im afraid makes you wonder on the quality of components used as
my hdmi input stopped working a while ago as well, so if anybody knows
how to repair that i would be interested,my panel is just 28 months old
hope this helps

Ln52a550p3fxza wont start cycles on and off


The problem could be temperature related. I replaced both my processor board as well as the power supply board and the problem is still there BUT I found a VERY simple solution that just requires me to keep the TV on all the time. When the TV is at room temperature, it literally takes 10-15 minutes for the system to stabilize and provide a good picture and audio. When my basement was at 55° for a few days, it took over 1 hr for the TV to stabilize. I now switch the input to my Roku player input and leave the TV on all the time. The Roku screensaver kicks in and all is fine with the world. No more issues with the TV not working. It adds to my electric bill but it is cheaper than replacing another board. When the TV dies, I'll get a replacement TV.

I have recently bought a Samsung SM2033HD TV and want to wall mount it. I can remove the base but how do I remove the collar that joins the base to the TV.


Your tv is not fully VESA compliant. You cannot remove the collar. There are mounts available that grip the screen instead of screwing into the back. This type will look better.

Samsung 40" tv not coming on


I would check out the power supply module for bad caps with bulging tops. Check DC voltages at the output connectors, you should have 5, 12, 24V.

It's simple. Your TV does not like you. Perhaps you need to speak kindly to it before you force it to watch BBC for hours. Buy it a scone.
