My RCA 56 inch projection tv will not come on. When I press the power button on the tv or on the remote, the power light just flashes three times and then it stops. The tv does not come on. I will wait a couple of minutes and then press the power button again, it does the same thing. Then after about many, many minutes the tv comes on. After, it comes on the tv flashes several times then I can watch it. What is the problem?

Your symptom sounds like a damaged convergence IC, whick you have found to be true.

There are two and large IC’s that control the convergence in a big screen set. They are secured to a very large aluminum heat sink.

Along with the convergence IC’s there will also be some associated components that will need to be replaced as well. There are some resistors that are part of the convergence circuit that will be open and need to be replaced. Most likely these will appear charred in the center. If you have an Ohm Meter or a DVM, check all the resistors that are close to the IC’s and you should be looking for either ones that have opened or have changed values.

You will also want to replace the white heat sink2.gif compound that is on the heat sink2.gif, just scrape it off, then clean the surface with alcohol. Then apply a thin coating of fresh heat sink compound, if you do not do this important step the new IC's will not last long as the old compound will act as an insulator to the heat transfer.

I would suggest that you contact a service center in your area for a complete diagnosis and repair, as this type of repair can get a little tricky. But if you want to repair the set yourself, just remember to be careful. The capacitors and CRT’s can hold a charge and may shock you.


If one of the convergence IC’s are found to be bad, I would replace them both, if one has gone bad the other may go soon. I usually order my parts from Andrews Electronics in California, they will have the OEM components that you will need.
Their site is http://www.andrewselectronics.com/welcome.aspx
And their phone number is a 24-Hour Order Desk: (800) 274-4666
I recommend the phone order so you can talk to the person about the different types of IC’s that are available.

I would also advise that the convergence IC’s be OEM or better, just because they are cheap does not mean that they are a good deal. I have seen the cheap IC’s fail after a short time, even though they look exactly like the OEM IC’s. I think that the bottom line is that you will get what you pay for when it comes to the parts.

You can also try http://www.tvrepairkits.com/ , I have not tried them yet, but they do carry OEM or better parts.

I hope this information allows you to resolve this issue.

Hello,

The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to.

I do not think it needs replacement, rather some defective capacitors are causing this issue.
Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.

The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)

You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.

What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).

You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors).
After replacing these capacitor(capacitors) most likely the normal operation will be restored.

Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.

If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.

I hope this helps.

Good luck.

Wont turn on


Check the solder connections on the flyback and also right next to the flyback there is a small white coil with copper wrapped around it that will sometimes arch causing the solder to need re-soldering

Sounds like the capicator on the high voltage is swelled,removing the back cover,make sure to unplug the unit first,there is a u shaped heat sink about middle ways of the board,inside that heat sink is a cap,it will be swelled on top of it,its a 2200 35v cap.
