SOURCE: Samsung 52 inch LCD - no turn on just clicking

most likely the power supply board has failed, but it could be the main board as well. call 1-800-samsung for nearest service center.

SOURCE: Samsung LCD TV, no picture only sound

My Samsung LNT4669F has two problems..the first is that it takes about 3 minutes to turn on. The red light at TV bases flickers on and off but the sound is there back and forth..Finally, the wite light at base turns on and the TV makes a noise as if it just got turned on and it stays on..why does it take so long?

Secondly, sometimes, the HD channels flicker so badly that I cannot even watch TV..so badly that sometimes the picture is blank..however, the regular channels are fine..Can you help?

SOURCE: We have a works 42" Polaroid with sound but no picture

The common issue with polariod is there power supplies, Your going to have to fork out something for the repair if you not willing to buy a new TV here, A new board in this would be $175 labor another $80 or $90 tops. So you getting into $250 fast. This is why I say to all my askers NEXT TIME buy a extended warranty. This will need a new power board sorry to break it to you and its the common issue I am seeing on fixya.com from my premium chat customers. Please do be considerate as this information was free to leave postive feedback and maybe a ranting or two.. for all those expert involved in your case today.

Tv turns on for a few seconds then goes dark but still have audio. Picture is barely visible if you stare at and concentrate


Most likely your backlight inverter is defective. On a set this big, the inverters should be seperate boards. It could also be leaky caps in the power supply, or a defective mainboard that isn't holding the "BL ON" signal. The tv is repairable but most repair shops will want to gouge you on price.

My samsung 42 inch hdtv is making a buzzing noise


First. The whirring or buzzing sound you hear is the Color Wheel and it needs to be replaced. Second, since I do not know when and if the original lamp has been replaced it is a good idea to replaced the lamp. The bad Color Wheel is the one causing the set to shut down.

Blurry picture


If the power to the tv was on when the power came back on it may have caused a power surge through the tv and could have knocked the allinment of the colour tubes out a bit you could try to reallin them via small screws on the colour tubes but you need the tv on an it can be difficult.

TV making high pitch sound


Hi, There are usually 1 or 2 fans inside the TV's. Could be worn bearings, or fan blade interference. Sorry, without my electric ear working, I can only guess.
