I have a RCA Projection screen TV Mod#P52754AT Ser#643580021. Will not power on with or without remote. Minor trouble shooting performed. Pls any help you can offer would be greatly appreciated. Ken


First thing I would verify is that power is being sent to the TV.
Check circuit breakers ect.
If you have a multi-meter verify there is AC voltage at the outlet the TV is plugged into.

If you do have voltage the next step is to verify the power supply / HV spliter is sending voltage.
Below is quick video on how to do that.
If components are bad, replace or repair them.
If it is good your problem requires more complex troubleshooting and a circuit diagram.

Be sure to check the output transistor. This is the most likely the cause. It is by the flyback, on a heatsink.

Have lost all sound on my Hitachi 55VS69A


Hello,


Let verify first to narrow down to where the problem can be. First, check the on screen sound set up menu to make sure the speakers are not set to OFF. If the setting is OK, then attach the powered PC speakers to the Audio Line out RCA jacks to see if you can get the sound there, if you do, then the problem can be in the power amp circuits, if you do not get the sound at RCA jacks, then the problem can be in the sound processor circuit. To get the sound repair, it can be from $150 and up, so if you can put up with using the good set of Powered PC speakers which actually give better sound than the tiny speakers inside the TV, I would keep using it that way, you may want to find out if the on screen sound setup will allow you to set the audio line out to be VARIABLE which means the sound output feeding the PC speakers can be varied using the TV remote control, then all you have to do is to set the PC volume to about half way up and set the TV volume to what ever you want.

I hope this will help in solving the problem....

Tv won't come on


Typical reset sequence is: unplug the set, press the power button a few times ( Yes, with the set unplugged ). Then, hold the power button down and at the same time ( maybe with your other hand ) plug the set in. If that doesn't do it, there may be a button marked reset on the back of the set. If there was a lightning strike nearby, your set is probably toast. The antenna or cable brings it into the house.
