    It's have been disconnect for more than 3 months already. I did try again last Monday and still the same. Someone told me about to re-soldering.

    The main fuse is ok. It's could be a flyback? or capacitor?
    Thanks for your help and advises.

Your description indicates that the power supply has failed; the noise you are hearing is probably caused by a relay that is interrupting the AC supply to avoid damaging the supply any further or causing a fire.
Disconnect your set from the wall and allow several hours (overnight is better) so that dangerous voltages have a chance to discharge.  You will have to gain access to the lower section of your system to look for a separate board with larger components on it, some cylindrical (capacitors), some block-like (chokes and transformers). If you can locate this board, it should be user replaceable.    

The next step would be to look for unique markings on that board looking like an assembly number. With that in hand and the model number of your set, look for the RCA service center in your area and call them to determine whether they have a repair or replacement assembly.
If only a replacement is available, keep the failed unit for possible repair in the future when the new one fails since mfrs. will not have entire assemblies available in a few years.

    I wouldn't try to talk you out of it but it is far more likely that the problem is caused by:
    1. Failed electrolytic capacitor (requires special meter to find)
    2. Failed semiconductor (easier to find but requires a multimeter)


    If it was my set, I would first try to find the bad cap (I own the equipment) and if there was no bad cap, do what I suggested in the first message.

52" rear projection tv has no power and fuse is ok


The clicking noise that you are hearing is actually the power relay. Normal operation by either the remote or the power button on the front panel, you would normally hear a soft click just after the press of the power buttons to turn the unit on or off. When you initially plug the unit in to power, you will hear the same click noise. Being that you are hearing it all the time indicates a failed relay. TV's now a days, or at least ones built during the last 15 - 20 years have different Printed Circuit Boards (PCB). There are PCB's for power (which youre dealing with now), sound,video and so on. The PCB that you need to repair your clicking issue will run you about 80 U.S. dollars for the part plus the average going rate for repair from a qualified service tech. You could purchase the part from Thompson Consumer Products repair and fix it yourself, but be aware, there will be no warranty on the part itself unless an authorized tech does the work. Located on this PCB is the power on/off relay, fuse, usually 4-5 connectors for power to different PCB's (depending on model and features). Now depending on how old the TV actually is, you may want to invest in a newr set, the reason why I say that is, is because the new power unit may and can overload the other boards and cause damage to them and now you have a new problem to deal with( along with more money being tossed down a hole.

Good luck

Will not turn on


Does the set make any sounds. DOes the front green led light or flash when you try to turn it on.. if not then it could be as simple as a fuse, if it does flash then it can be many problems
