My TV is blue and says "no signal" when I turn on my PS3. I haven't used it in months, and have only used it about a dozen times in total, but it's always worked fine in the past. I'm running a HDMI cable into the TV. The TV picked up the signal for about 5 minutes, but then went right back to saying "no signal." The cable seems fine. I tried resetting the system by holding the power sensor for a few seconds until it beeped, but that didn't solve anything. Anyone have any ideas?

This happens when you change the output settings to HD, then switch back to regular a/v because the tv dosen't recognize the signal. Thankfully there is an easy fix. Just turn the PS3 system on using the power button on the front and continue to hold it until you hear a second "beep" sound from the system. then picture should beging to work again.
Your A/V cables might not work anymore. Do you have any spare A/V cables....like from a ps2? Try the cable on your ps3 to see if you can get a signal then. If you don't get a signal it is a problem either with your ps3 or the TV. Try using a different TV, if it continues to happen than it's your ps3. I highly doubt it's your ps3 and doubt you will get to this step, but if you do what you need to do next is buy an HDMI cable and hook it to your ps3 and tv. If your tv doesnt accept HDMI than i dont know what to tell you. If you do this step and it still doesnt work than sorry it didnt work. Hope this helps, good luck.
To solve this, when the ps3 is in standby (solid red light), just hold the power button. It should beep on, then beep again in about 5 seconds. This will automatically search for the optimal audio video output. if if beeps on then turns off, just try again, it takes 1 or 2 tries sometimes. the reason this is happening is because your ps3 is set to one AV output, ex. composite(red yellow white), HDMI, and then you changed the cable to a different one. another way to fix it is plug both cables, HDMI and composite, into the tv and ps3, then go to settings and change the output to the desired one.
Try holding the power on button down until you hear a series of beeps, each one representing your ps3 switching video modes. try this until you get a picture on your screen, then you can use the options to set it to your tv's resolution. I've seen this same problem often from people holding the button when they turn it on :3.
