Question about RCA D52W23 52" HDTV CRT TV

1 Answer

Exact Same Problem. TV turns on, sparks, then shuts off.

Took off cover on back and sparks seem to be coming from just behind the flyback (with the red wire). They are coming from underneath a grey component. I could provide a name/number if I could look at a diagram.

Your most likely talking about clo31 which is a 0087 2000v box capacitor. You can get the replacement at the following link.

Hi. It seems that the g2 voltage of the picture tube is too high, resulting in a white screen, often with white horizontal lines. The g2 (= second grid) voltage is derived from the flyback high voltage. The voltage divider is mostly integrated in the flyback trafo housing.(including the adjustment knobs). A failure in this divider may lead to this defect. The static you hear may come from sparking in the divider. The flyback trafo is soldered onto the main printed cirrcuit board. Sometimes, one of the pins sits loose in the soldering pads.
Turn on the set and observe for any sparking around the entire flyback circuitry, and, or the flyback trafo itself
The screen turns black after a while, as a too high beamcurrent is detected. The set disables the flyback. Stand-by blinks meaning that there is a fault condition.
Be carefull with the high voltages. The flyback voltage is very high (20-30 Kilovolts !) and may be lethal !!

I'm trying to fix my 21 inch JVC TV, its on standby mode i detected the problem it was Horizontal output transistor, when i replace it with new one it work but after 24 days it got shorted again so i...


depending on circuit design in some TVs when flyback becomes defective then (1) only flyback gets deffective or (2) flyback & 1 transistor big in size fixed near flyback gets deffective or (3) flyback,big transistor & resistor or diodes or some times ICs will get deffective ..........so flyback replacement is compulsory + which ever components gets deffective ....... usually flyback gets deffective after 4yrs (between 4yrs to 12 yrs depending on TV brand & usuage ) .............so in your case along with horizontal transistor replace flyback also ..................... Remove that flyback from main board ? using marker make a mark (1 dot on knob & at the same line put another dot on flyback --- these 2 dots should be in same line ) on all the knobs on fly back ....now turn all the knobs one by one in anticlockwise direction slowly until it stops .... Then observe from the mark which you made before turning .. --- you will get an idea which knob howmuch it was turned in anticlockwise direction.... now take flyback to electronic shop & buy same type ( equivalent will not work )......at the shop itself check part number , number of pins & their position of old flyback with that of new flyback ----- everything should match 100% - nothing less nothing more .... it should be exact .... check many shops...now turn all the knobs of new flyback in anticlockwise direction very very very slowly until it stops....now fix it to mainboard very slowly & carefully....don't forget to connect red wire from flyback to TV TUBE ...again iam repeating don't forget to connect red wire from flyback to TV TUBE .... Now observe mainboard carefully whether any connector is not connected ....now connect only tv powercord & stay at a distance & switch on Tv for 2 seconds & then switch of immediately....during this 2 seconds TV gets on & led also gets on continuosly (won't blink) & there should not be any smoke or sounds on main board ...this confirms you have replaced flyback without disturbing other components & not shorted any joints..... so now again switch on tv ..wait 3 or 4 seconds ...led will be on but there won't be any picture ... Don't worry ....in the beginning you have observed howmuch knobs on your old flyback were turned in anticlockwise direction....remember..? see your old flyback again.... Now using suitable screew driver turn all the knobs on new flyback in clockwise direction one by one very very very slowly ...untill as it was in old flyback ( approximately ) --- remember TV is in on condition ... means high voltage will be there ... bymistake if you touch any part of the tv .. you will get very severe shock.... So be very very very carefull ..now while doing this adjustment observe what is happening on the screen - how brightness is changing ... Now switch off tv....connect signal ( antenna or dvd or cable..) & again switch on TV ....so now depending on brightness & clarity of the picture ..looking at the tv screen again you have to turn 1 or all the knobs on flyback either in clockwise direction or in anticlockwise direction very very very slowly ..once you start doing this adjustment practically then automatically you will come to know which knob should be turned . in which direction - & howmuch it has to be turned .... But remember this adjustment is very important .. Sometimes it will take 30mins to finalise the exact position.of knobs .. so take your owntime & finalise the exact position of those knobs..then switch off tv ..fix back the tv cover .. then switch on tv again ....that's all .......100% GUARANTEE again your tv will work normally ....vishnuswamy_23.jpg

The bottom half on the RCA D52W19 has been removed and the Flyback on the Back right corner emits a noticable spark when attempting to turn the television on. Is this a flyback problem? Or is this a sign...


this is the flyback. it is not uncommon for this part to be bad and spark. Now it is common if this part is bad then the horizontal output transistor is shorted. this part is located directly in front of the flyback on a large heatsink.

Tv tries to turn on 3 times


Thats usually caused by bad capacitors or a bad flyback. www.tvrepairworld.com has the capacitor kits and the flyback kits available for your model.

Tood my D52W20 to Repair man and he said not worth fixing.


The repair man doesnt know RCA 's very well. The 3 x then out power led is the classic sign of the flyback and cp150 needing to be replaced. You need the flyback # 259296 and the CP150 you can get the flyback and cp150 at the following link with free step by step instructions with pictures on how to do the repair. Its very easy. Heres the link.

Mitsubishi WS-65857 RPTV Popping/Sparking/Crackling Noise, Then No Picture


When they list two flybacks like that it's usually for different models,
>>do you think I might have caused more damage to other parts by continuing to turn it on after the initial symptoms? Those loud pops did not sound good.
more than likely not but who knows.

crackling nose like that is a good indicator of flyback or crt being shorted.
some times you can look on the neck towards the end of the tube and see inside the tube arcing, but then again your picture should be all messed up if that was the case.

TV makes a repeated cricket sound and won't turn on.


It means that the TV set has a short in it somewhere. The sound you hear is the power supply trying to start up and shutting down. Most likely the Horizontal output transistor shorted because of a bd high voltge flyback transformer went bad. Common problem for these types of sets. Good Luck
