Question about RCA D52W20 52" Rear Projection HDTV-Ready Television

Open Question

Replaced the flyback and capacitor anode cable?

I had the same issue with this tv, and I've been reading about the issues that seemed to all be related to the flyback and capacitor.

I ordered the parts online, and replaced them.
The thing that bothers me the most is the connection on top of the flyback.
(the red wire) anode cable I think is what it is. When I shine a flashlight down into it....it looks as if theres nothing the wire connects too.

I turn the TV on and I'm getting the same thing ( the green light flashes and then it cuts off) I can hear a faint clicking noise that sounds like static....but that's it.

Should I be leaving the TV plugged in for it to build up a charge?

Am I doing something wrong?

SOURCE: replaced the flyback and capacitor anode cable?

Did you check capacitors CP150, CP120 and CP114 to see if either are blown?

"4 capacitors on the power/deflection board. CP110 220uf 200v. CP120 220uf 35 Volts. CP114 220uf 35 volts. CP150 2200 16 volt. also check entire delfection board for cold solder especially around flyback. bad connections here can cause problems like some of the fp fuses blowing and cutting off convergence supply"

I have a 52" rear projection TV. D52w19b. Green


Make sure you resolder the flyback and recheck any RCA fuses that may be blown - they are usually near the flyback. If this does not help check the site www.tvrepairkits.com for repair kits or tips for your projection tv model.

My LCD TV Series 530 keeps on blinking and would not turn on. why does it keep doing that?


I've experienced similar issues with a 42" Samsung LCD TV. From what I've read online, I believe it could be a problem in the circuitry of the power supply. Apparently, Samsung used under rated capacitors in the power supply and the result is a turn on delay or blinking on and off. If this is the case, then the capacitors would need to be replaced to fix the issue.

If your tv works fine in viewing movies in dvd or cable there is no problem with the tv. Your right about the compatibility issue you must manually change the graphic format of your computer but if your tv has an HDMI output try to connect your pc in that input. Hope this may help good day and best regards.

TV will not come on. Cord and fuse OK. There is AC voltage on anode and cathode of silicon rectifiers but no DC voltages.


Hi lou,

Do you have voltage on flyback to tube?

RCA D52W20 has no anode cap (Discharge how)


On end of the red wire from the flyback to the top center of your CRT (picture tube) there is an anode cap. Get a wire clip and a long screw driver that has an insulated handle. Attach one end of clip wire to known ground on TV chassis and the other end to the screwdriver. Now carefully slide tip of screwdriver under the anode cap. You should hear a little snap. Now the CRT is discharged.

Good Luck, Big Irish.

Wires going to flyback transfomer


Wires going into the flyback are not removable but are integral to the flyback. The three wires comming out the flyback are the thick red one (anode button) which attaches to the tube is removed by pinching the button to release the clips on the tube. The other wire probably white is removed by unsoldering it from the small board on the neck of the tube and the 3rd and last wire is probably black, this is the one you may have your issue. To remove this wire, you must disassemble the tube socket..look for two tabs..pry open gently and seperate. Then with a small jewelers you'll be able to release the black wire..hope this helps.

HD52W140 will not power on


Hello rsherrett1,

Ok first of all the only way the trippler could have caused this was if it shorted, and you would have known if that happened, because of the fire that would have occurred. So let's go back to square one. did you check the primary power supply in the back of the chassis? check it first for a blown fuse. I you can not find that then disconnect the power connection to the high voltage board and secondary power supply (switching power supply) and see if you can get the supply rail to the secondary board up (you will need a schematic to see the voltage values that should be there. Now if that fails to produce results you will have to assume that the secondary power supply is the culprit (it usually is). The funny part about this is the one component no one ever tells you to test is the one you should test all of the time and that is the IHVT (Integrated High Voltage Transformer) some folks refer to it as the "flyback" transformer. Now one of the biggest problems happens at this point there are three tests that you have to run the equipment needed is a s follows:

1) an oscilloscope

2) Universal Signal Analyzer/Generator with Ring Test ports

3) A capacitance meter or a LCR 103 (I prefer the LCR103)

4) an ohmmeter

Now here is what you need to do to test the IHVT

1) Remove the IHVT from the circuit board (desolder it)

2) Remove the HV cable clamp (holding the HV cable to the base of the IHVT)

3) (Test 1) Perform a resistance test between the posts of the IHVT looking at the schematic to see which posts are wired to each other. (now this test is only good for pointing out open coil windings not shorted coil windings) if this test passes (no opens) go to test 2

4) (Test 2) perform a ring test of the IHVT. Now this is why you need the Signal Generator with ring test ports. Connect the cable from the ring test ports to the primary side of the transformer, see the schematic to determine the primary os the transformer (the side connected to (actually between) the Horizontal Output transistor and the power supply. turn the ring test actuator fully counterclockwise, turn the test selector to ring test and slowly turn the ring test actuator clockwise until the screen reads greater then 10 rings, if ten rings can not be achieved then the IHVT has a short in it and should be considered as bad and in need of replacement. if this test passes go to test 3

5) (Test 3) The last test is the capacitance test. This test is a test of the internal capacitance of the IHVT. This is measured from the HV anode of the transformer to the ground post of the transformer. connect the negative end of the capacitance meter to the ground post of the transformer and the connect the positive end of the capacitance meter to the anode of the IHVT (this is the end that the cable was removed from, You will have to use a probe with a wire attachment to it to make contact with the anode connection in the IHVT. Once that is done the capacitance meter should read around 2.7nf or above. A reading of .3nf means the capacitor is open. Note: However certain flybacks may have the value of 4.5nf, 6nf and 7.2nf and sometimes the internal capacitor pin is connected to circuits (feedback) instead of ground, so be aware of this when testing. If this test passes then the problem is not the IHVT.

However if any of these test fail then the IHVT is to be considered as bad.

Now if the IHVT is good, then you will have to test the following components and their respective circuits:

The Horizontal Output Transistor, The Switching power supply MOSFET, The switching power supply transformer (perform ring test just like the IHVT), and pay special attention to the capacitor on the 6 volt rail (This capacitor is known to go bad often) as seen on the circuit board, The schematic will have all of the part location numbers as seen on the board.

This is a logical start as opposed to the shotgun approach a lot of forums seem to lead to. Let me know if this helps you.

Thank you,

Tv screen went blank. When I unplug and plug back in I here a hissing Lg 42 flatron plus 6 years old.


do you have heater voltage because if you are hearing high voltage you may need to replace a resistor and capacitor in the 200v circuit or you could possibly have a anode not seated right arcing on somthing or a bad flyback

usually when thiers arching its usually inside the flyback connection that causes the arching.I reccomend changing the flyback.
