Re: Change the vertical frequency to 60HZ on Samsung LT-P...
I'm sorry to say that this LCD is for Standard NTSC, HD-ready, PC-ready only and will not work in Europe unless you can get some NTSC signal. There is not way to change the internal settings because you will also need to change the tuner and many other parts. At this point the cheaper solution will be to buy a multisystem LCD that will work with PAL and NTSC signals.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repair professionals here in the US. click here to Talk to a Technician (only for users in the US for now) and get all the help you need. Goodluck!

Hello Frame output IC means nothing, but the VERTICAL OUTPUT IC. Every TV will have it, which will scan picture vertically at 50 or 60 Hz. [1 HZ means one frame per second. Normally TVs will have 50Hz, 60Hz and 100Hz vertical frequency]. As vertical frequency rat increases, the picture fliker wil decrease. High level high-cost TVs will have 100Hz or even more frequency will be used for vetical scanning. In the case of computer monitors, the vertical frequency will vary from 60Hz to 120hz. You can see its picture stability, at this high frequency. The IC [Integrated Circuit Chip], which generates the vertical frequency and outputs it called the vertical output [frame output] IC. OK

The tv power supply board is not the problems,that can add a transformer to solved it easily.The problems are US and Europe uses a difference tv signal frequencies.The US,Canada and Mexico are using a NTSC signal frequencies.Europe,Asia,Middle East and Africa are using PAL signal frequencies.U must have a tv that call REGIONS free tv to work in Europe and US same time.If u just have a standard LCD or a Plasma HD tv buy it in the US for example will not work in Europe
Modern TV's haven't got a vertical hold control like in the old days. The TV system now uses a system of counting. For instance; UK is 625line which is 15.625KHz line frequency. Divide it down by the correct amount and we get 50Hz frame frequency. There is no need for external controls. That is how copycode on video works. Supply 620 lines and in the end that is not divisable to give 50Hz so video cannot be copied as TV shows the wrong speed frame and will cause no colour and picture disturbance. Likewise the same rule applies to USA 60Hz system.
I have the same problem and i was thinking of changing the board 50-60 euros max. Also i have service manual with steps to put the machine in service mode but never found out how to reset power frequency sensors. If you need service manual firstname.lastname@example.org
NOT unless it is a DUAL frequency Standard, as Europe is PAL & SECAM, USA is NTSC. Also the HERTZ is different too 50Hz Europe, 60Hz USA, so really NO. IF it would work, it would have an international power supply, meaning it was usable any where in the world. and also it would have a multi tuner. Otherwise it will NOT go.
This is a problem that will pretty much just be there on this TV. I know it has an awesome picture...as long as nothing moves. You can try putting it in "Game Mode" in the user menu and that usually takes care of it but you didn't buy the 120/240 Hz tv to watch it in 60Hz. I would say exchange it, and in my opinion buy a good plasma :)
Please check the Broadcast System setting of the TV. It should be in the correct setting. If you are in the USA, it should be NTSC and Vertical frequency 60 cycles, if you are in Europe, then it should be PAL (I, or B/G) with 50 cycles Vertical frequency. Once you have made the correct selection, the problem should resolve.
This looks like it could be a problem with leakage of the 60Hz vertical scan frequency into the picture this is also called 60Hz hum. What usually causes this is poor filtering on the power supply or decoupling capcitors in the vertical section have begun to malfunction. This problem is easy to fix if you have the equipment to isolate the problem, I would suggest that you take this set to a TV repair shop to have it analyzed and repaired.
