Re: Having Problems getting my tv to turn on
It could be a Flyback transformer problem. Check th flyback for loose solder move the transformer a little bit and look on the underside of the circuit board. be careful ther may be current left over. Put your left hand in your pocket.or away from you. if it is not that you may have a faulty circuit board (burnt resistors) near the yoke going to the screen.

i have seen before that model have some problems with the lamp door switch. check the back of the tv and make sure that the lamp door is secure otherwise it can be possibly a color wheel or even lamp failure. if you have never replaced the lamp then i would lean more towards that as the root of your problems.
This tv have a colors wheel.The colors wheel is dead.The tv have squiling,motor loud noises and back&white picture.All the indication problems of the colors wheel is dead.Call the tv tech.to fix this problems,because have to take out alot of manchanical parts.Before even can get to the colors wheel out to replaced it.
You may have a colorwheel going bad. The bearings start going out and this is an indication of the failure. The colorwheel is located in the light engin e therefore you may want to get a qualified tech to look at it
Good day, dkimberly428;
Sorry you are having a problem with your SNG TV.
Let me ask you why did you replace the color wheel? Was it making noise, but had pic prior to changing it?
Okay, if that was it, try this: the color wheel ***'y has one cable and "ribbon type" cable, correct? Okay, make sure both cables are secured. Secondly, the "ribbon type cable" was more then likely put in backwards. If I remember correctly the shiny side (end) of ribbon cable should be facing the rear of TV.
Good Luck, big IRISH. PS always double check ALL cables in TV to make sure they are properly seated.
I just responded to your other post check the connection between the lamp and ballast at both ends. Also did you get the same exact lamp as your old lamp, as Samsung has two different arc gaps and they wont work if you get the other type even though they look the same physically.
Is the lamp light the only one thats flashing? Does the buzzing your hearing stop or is it constant? Also when you press power off does the buzzing stop instantly or continue? Respond to this post and I will try to assist you. Is HL-R677w the correct model number also?
White lines evenly spaced, across the screen is normally caused by the DMD.
When replacing the DMD, the light engine must be pulled from the set.
After the DMD is replaced and the light engine is returned, a mechanical alignment must be done and then the technician pulls up the service menu and aligns the Index Delay and SP actuator.
Hope this helped.
