    We were watching it and the picture just shrank starting front the outside and working working to the center and the unit turned off. Now it won't turn on. The red light on the front stays on if I try to turn it on with the remote.

    All 4 side shrank into a small square with straight lines.

    I have the same problem. Both of the sides of the picture would jump then the picture just went out. I had a tech come out and said one of the part went out but it had been upgraded and you had to buy another part but that part is no longer available. Samsung is trying to give me a run around but Sears told me that if I can't get it fixed then they owe me a new TV, I have the part that is out but can't use it because of the upgrade. I need to know if I can put it in and fix it or do I need to find out about the lemon law.

I had that same TV and just now got the Mainboard replaced for the 4th time. Under the lemon policy warrantee at Bestbuy they are letting replace it with a Mitsubishi WD-65733 and I am totally phsyched. This TV is a lemon, "Get rid of it" while you can.

What exactly is the problem with the set? Why not just fix the board that is in there? Usually, only a lightning strike that completely burns up the board or a coolant leak from one of the picture tubes that covers the board and corrodes through the parts and traces are the only reasons to replace a board. Explain exactly what you see or exactly what is wrong and we will help you from there.

    Did the picture shrink in from the left and right sides only? Were the sides straight as the picture shrunk or were they bowed inward? Did the picture collapse inward from the top and bottom too?

    If all 4 sides shrank, I suspect that the power supply is defective, and there is a switching IC which could have given up. Power supplies are quite easy to fix, so have a qualified tech look at the set.

Replace all electrolytic capacitors in power supply section on mainboard. caused by poor quality lower voltage lower temp caps being used in powersupply and being put right beside a heatsink (Der are we clever or what) . Problem will reoccur every 2 to 3 years if 105oC caps are not used. If mainboard is replaced with new mainboard problem will reoccur within same timeframe. Fix old mainboard using higher voltage and higher temp caps and problem will be gone for good.

Mixed colors and separation of colors


Common problem known as convergence. The most common reason is the failure of convergence ics. these ics fail all the time because there big and get fairly hot. there is a possiblity that it can be reconverged if the convergence cuircit is not damaged

Samsung hcn653w power surge


If the set went dead during a storm and will not power up at all, first try unplugging the set and waiting an hour or so, and then plug it back in to a working outlet and try turning it on. If the set still will not respond, your power supply has stopped working and should be serviced by a qualified tech familiar with Samsung projection sets.
