It cold be the power supply is going bad for your TV and that the TV is starting to die on you guys and it would be more cheaper to buy a new TV than to try and repair the old TV that is no longer working anymore.
My Samsung started doing that and it got worst and worst. Searched the web and find answer. It was the high voltage circuit. All TVs now are like computer and it check for 390 to 400 volts and if it is below, the TV will not turn on. Good thing the Samsung has only one capacitor showing the high voltage circuit. Measure the voltage was 381 volts. The capacitor was rated at 100 uf at 450 volts. From some old TV and power supply, got two capacitors rated 150 uf and 220 uf both at 400 volts. Had to connect them in parallel and took out the old capacitor. Now, my TV works fine.
Most likely failed capacitors in the power supply. I am currently having the same problem with my 26 month old LN46A750. Samsung has agreed to fix this as an out of warranty "courtesy repair".
consult manual for troubleshooting it could be that lamp in tv takes long time to cool down or that it is bad they usually last about 2-3 years depends on how you use your tv
I have sound but my tv screen is black. Sometimes when I turn on the tv I get a picture but after 15 minutes or so the screen goes black again.
It's a 4 year old LCD.
There are 3 capacitors in power supply board, all 1000uF10v.
2 for 5vdc and 1 for 12vdc. replace with best quality 1000uF 25V cap.
do it yourself repair will save you $300
I had a problem with a Samsung 46 inch LCD and it had audio and dim light but no picture and found out that the logic board toward the top (inside tv) was bad and was no longer available and the only way to fix it was to get the entire display panel (the logic board came with it) It was not costwise to repair. Hope this helps.
