HELP ME! RCA HD34 Moniter

[Ahles_5]

I'm needing help or any advice! I have a RCA HD34 Moniter that is having problems starting up. When I power on through the remote it tries to come on three times and nothing. It's been doing this for a short time and as of yesterday it just never came back on. Any ideas???

It might be a power supply problem. It tries to "start" three times and after those failures it stops. Are you able to hear any high pitch whines or clicking while this is happening?

[Ahles_5]

yes, a click and whine...

have you tried just unplugging it for a while? letting it discharge maybe overnight?

I know that this probably isn't any help, but I used to have a TV that acted like this once. I checked out various voltages and found that the voltage was wrong very near the AC power plug. It's been a long time, but I remember that there was some kind of AC voltage control around the power. I tried to fix it but failed, and finally just put the TV on a variac (ie a variable transformer that allowed me to adjust the AC voltage going into the TV). On the variac, the TV worked fine. I can't remember if the voltage was too high or too low (I think too high). The variac plugged into 120V AC, and the output was variable from zero to 140, so I had the capability of increasing or decreasing the voltage. I think the TV had some sort of protection that kept it from turning on if the AC voltage wasn't within a certain range. This was a TV from about 20 yrs ago and went bad about 10 yrs ago, so modern TVs are surely different, plus you probably don't have access to a variac to experiment, but just posted as it could be a problem even prior to the DC power supply, and/or perhaps the AC power in your house is too high or low. I know that this particular TV worked fine where I used to live, but I moved to a place that had AC power that was a bit on the high side ( like 122 ), and the TV wouldn't work in the new house.
