that sounds like the CP150, CP120 and CP114 capacitors have failed. The RCA repair kit by that same name works for your model GE also. Its available from www.tvrepairworld.com the kit contains the capacitors and the CD with instructions for the repair.

Hi. I have a 2004 52' Flat screen projection TV. For the past couple months, we have turned on our TV and all we hear is sound, but no picture comes up. We thought the bulb was having problems. We ordered...


The buzzing is the ballast arc gap,normal sound. When the tv starts does the lamp start to come on. Can you see any light from the back? Sounds like bad ballast. Unfortunatly this part is no longer available. the light engine will have to be removed and sent to Toshiba to be rebuilt.

Picture scrolls and is offset


Oops, nevermind. It's right there up top.

First off, try a TV reset. Leave it unplugged for 5+ minutes then try again.

If this doesn't work, I would recommend contacting RCA. There is no way to contact them as far as I can find, except for an online form to their customer service (there may be a contact number in your TV's manual):

Good luck,

Blinking green light and clicking noise AFTER bulb replacement


do this. press and hold device and menu button on set for 5 seconds. this will retrieve a 2 digit error code .. the led will flash the first digit and pause the flash second digit. This unit is known to have capacitor problems on the power board. getting to these capacitors involves taking alot apart. let me know error codes and we can continue troubleshooting

TV does not recieve a remote


Hey, Have you tried to power cycle your remote? That may work, do the TV too. I'll give ya the steps, just follow them and you should be ok. I'll throw in a factory reset as well, but if you're not using a cable box you will have to run another auto scan. anyways start off by unplugging the TV and removing the batteries from the remote control. Let them both sit, you don't have to let the remote sit really, but I do for good measure. You have to let the TV sit for a minimum of 5 minutes. at the end of 5 minutes, you have to find the physical power button on the TV, this means NOT on the remote, but on the TV itself, you have to find this power button, and you have to hold it down for 1 solid minute. Again, any time you can do something extra for good measure, it can't hurt, so if you want to leave it unplugged for 10 minutes and hold the button for 2, go for it, it may help. After you're done with that, power cycle the remote control. Being that your remote seems to be haywire, go ahead and press every single button, this means channel up and down, even if they're on the same button, every one from the top to the bottom, 5 times with no batteries in it. Then hold down the power button on the remote for 30 seconds. Then replace the batteries, preferrably with new ones. This completes the power cycles for both the Remote control and the TV. Now, before plugging the TV back in, we have to do the factory reset. Again, hold the power button on the actual TV, and then, while holding down the power button, plug in the power cord, wait for a couple of seconds, and then release the power button. Wait for a moment, and then turn the TV on. This completes the factory reset.

The reason for all of this, is, power cycle the remote to drain it's capacitors and reset it, power cycle the TV incase the Remote sensor is affected by a static electricity build up. Factory reset incase any settings may have caused this. Hope this helps.

Power light flashing/ no picture


I have the same problem. The only way to get the TV to come on is to unplug it, but once you get it back on it turns itself off again in a few minutes.
