Element 26" elchs261 sound but no picture I've tried replacing most of the capacitors but nothing. When powered on the brand name element could be seen the left side of the screen appears dimmer then the blue screen appears for less than two seconds then nothing. I could hear sound but no picture I then placed a bright flashlight against the screen and I'm able to see the picture but only the diameter of the flashlight so as I move the light to different areas of the screen I'm able to see the picture. I was told that the power supply board needs to be replaced but I can't find any where every site shows out of stock. I've checked the voltage and it appears to be ok. Now on the main board there is a resistor that becomes extremely hot using a temperature probe the meter reads over 400 degrees in about a minute after powering on. Can any one help please I would greatly appreciate any solution available thank you sincerely M&M bar. Power supply board model# rsag7.820.1235/roh ver f. Main board model # rsag7.820.1528/roh ver c

You expressed you have already changed most all the capacitors, I would have suggested you to do this too. Since you already have, I would start analyzing some of the other components of the LCD display. Have you took a look at the lamps? Making sure that the bulbs are not burnt out or on the way to burning out is important too. There are a few reasons why this may be happening. Post some pictures up if popssible it may help me further grasp the situation.
