Question about RCA HD56W58 56" TV

1 Answer

Won't power on. Burning smell, High pitch arcing sound,

I found a component under the screen, easy to get to, that has the part number 1590395a that is burnt. It also had VDE Reg N. 7403 506, 70211506334488, TCE 70234 , 1/feb/2005 on it, 1517923, CAV2, Sub 3. It resembles a distributor off of on old car, tan in color with a waxy looking substance on the botttom. I haven't been able to find the part on the web yet, Just found it today. Any ideas as to what it is and how to get it. I am a CATV/Phone/IT headend engineer and I deal with electronics all the time, but have never worked on a TV. Lack of experience has never stopped me b4 so why stop now?

    I am having the EXACT same problem. I turn on the set, and get a high pitched screech/squeal from the front speaker, then no noise and the power light satys on for a few seconds then flashes a few times then goes back to solid for about 30 secoinds before shutting itself off.

I have unplugged because of smell and i could hear a crackling noise, i have completely unplugged but smell is getting worse, i the tv is 10 years old


It sounds that there is some arcing takes place inside it. High voltage arcing will produce and Ozone smell. Contact any TV technician. Never use this set at this condition. It might lead to more fault to internal circuit components.

I love my tv so I hope you can help. It made a high pitched sound, then just shut off and there's a burning smell. Any ideas would be welcome.


UNPLUG SET if you have not done so--fire hazard exists.

I would open rear and LOOK--see what if anything you can see that is burnt---all parts will have a location number printed under or next to them---will point to where problem is---make sure set not plugged in and do not stick your hands inside.

I found chirping noise problem


If your set is an RCA which I believe it is, you can contact RCA to find their part distributor for your area.

How did you determine that these parts are acutaly defective???

When these types of parts are defective, the cause must also be found. When replacing the parts, they will probably fail again unless the underlying cause is found. This will require the proper training, service manual, TV service experience, and the proper tools for troubleshooting.

As for changing the parts, you will require the proper tools and soldering equipment. After all the faults are found and the parts replaced, and the set is working, it is best to verify the power supply performance, the high voltage regulation, and the operating temperature of the various components effected in order to insure reliable after service operation.

Television won't power up


It sounds like the high voltage circuit got damp and arced. This arc caused the horizontal output transistor to short.
You might try replacing the output transistor if you're experienced in this type of repair. If not then you need to take it to a repair shop.
The "whistle " you're hearing is the power supply indicating that it has a short on its load. When the power supply has an over load (short) its frequency drops down when your ear can hear it oscillating. This type of power supply is a switching power supply normally operating a several thousand hz(cycles) which is out of range of human hearing.

High pitched rattling not associated with TV audio


Quite possibly the HVT arcing, which will eventually fail.

The problem with them arcing is they can be doing damage to other components.

Best to have it checked by an experienced tech.

It seems it's one of those "vintage" sets. I don't imagine that the problem is very major since such (older) sets are known to develop bad joints, especially around the larger components (funny, sounds just like a problem that humans have). It might not be necessary to replace the LOPT. Just resolder as many joints as you can see. Usually the ones reponsible for arcing will leave visible signs of burn. The acrid smell you detected was probably ozone (given off when high voltage ionizes oxygen in the air). Good luck, if you haven't already solved the problem.

NO PICTURE, JUST A HIGH PITCH NOISE, SMELLS LIKE SOMETHING BURNING


Very common problem with these sets. The High Voltage transformer and the horizontal output transistor is most likly the problem.. If you know the saftey issues involved and know how to solder and unsolder, you can repair this set but theres a possibility you could also have a fault in the horizontal driver circuit, such as l401. if your not a tech its best to have this set fixed by a trained tech, if you wnt to spend between 175 to 225.00 Good Luck
