If the power supply outputs are good! Then I would say the back light inverter is bad! If the screen stays black and does not come on.

SOURCE: 32" Samsung TV, No Power or Sound, power LED on, flashes 3 times

Most likely the set has lost vertical sweep or the feedback from that circuit. This will shut the set down to prevent a horizontal line from burning the face of the CRT. This will have to be looked at by a technician.

SOURCE: samsung led tv will not come out of power

Sorry... this is not a solution, but I wanted to speak directly to you and didn't know how else to communicate with you!! OMG!! My t.v. does the exact same thing!! The power issue and the sound going out after it has been on for a while!! Have you called Samsung yet? I hear they have horrible customer service. Maybe if we get enough people with the same problem we can get something done about it!!

Open and look for swollen capacitors

SOURCE: Visio p42hd, no picture

Yes it does sound like the mainboard. But we have to confirm. I will see if there is a service manual for this unit in my collection but do you think you can safely work on it? Have you worked on electronics before? The last thing I want is you hurting yourself trying to fix it. HV circuits are not to be messed with unless you know about them.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

My samsung 61in. Dlp screen flashes green/blue pic is viewable but everything is the two colors, also screen will flash icon check fan #1


You have 2 problems. Problem 1 either you main board or light engine is bad and needs to be replaced. Problem 2 is exactly what your TV says. Fan#1 isn't functioning properly so a heat sencor is being actiated to shut down your set. Make sure all the fans are free of debree and spinning. If one is not spinning, make sure it has voltage going to it. This will let you know if you have a bad fan, or a bad board.

My TV just power cycles itself...


Most likely it is overheating, most likely cause is the fan is bad or the circuit driving the fan is not working. It goes through a cooldown cycle. this is the most likely reason. if it is just the fan it may be relatively cheap to fix. this problem may also be related to another circuit in the tv overheating or bad capacitors on the circuit board.

I have a samsung hlp5063wx. I just replaced the color wheel. It worked fine for two days. Then no picture or sound. After I turn the tv on the lamp LED on the front flashes. Then it goes thru its cycles....


If the color wheel doesn't spin, the lamp will not fire. The lamp has a gap in it, it will read open. Pull the rear cover off trip the door switch and look close and listen. Double check that the color wheel does not spin up (turn on, then wait 5 secounds or so.. pull the power cord and listen for it to stop.. best method). Also, watch the lamp driver.. there is a condensor coil on there that will lite up when it is sending the ignition pulse to the lamp... do you see it? If so, it's the lamp.

Samsung HLP4674W - changed bulb - still no picture - lights flash


If the lamp has been replaced I would think the Lamp ballast would be most likliest followed by the color wheel and then the Digital board. You can get any part needed for your model at www.tvrepairworld.com just leave them a email they respond quickly.
