Question about Samsung Touch of Color LN52A650 52 in. LCD HDTV
LN52A750R1FXCZ on live or PVR goes blank. No sound or picture. If I
rewind and replay that blank spot it will replay it normally, so its the TV
and not the broadcast. Happens often for 3 to 10 seconds.I bought it in
Dec 08 . Doing it from beginning. Also my entire screen goes pink
sometimes.OFF then ON fixes that. How do I fix the problem and is it a
sign of bigger problems to come? TV is 750 series. Entered 650 as
there is no product entry for 750 series. Thank you

if this is only happening on your dvd player, then change the type of cable used to link the tv with the dvd player, if that does not fix it then try another dvd player to make sure it's not the player itself

You need to check the back light is still on when the screen is blank (check through the back).
If the back light is on, need to change the Powwer Board.
no back light, need to change the inverter.

There is a bad capacitor on the circuit board which is quite common. The IC"s usually need to be replaced. The convergance is off due to these faulty capacitors.

It sounds like you have a Power Supply Board problem. The PSB is the center Board (towards left) after you remove the back off the TV. Remove Board from TV with the 6-7 screws. Replace capacitors CM852 & CM853; 2200ufd 25volts.
Thanks for using FIXYA, big IRISH.
