    Does the arc come out of the flyback transformer? If it does, then you will need to replace it first.

Sounds like a bad high voltage transformer (FBT). Call a service center.

This transformer does not come with the hv lead,if the arch is coming from the side of the transformer,cut the side of the plug were it goes into the transformer and the lead will come out,there is no voltage stored on the hv lead after the set is unpluged for a few min.,the transformer you can get at any rca repair center.

You can order a replacement Convergence Board or Convergence Amplifier Board for this model (PS8069) from a major RCA parts distributor at the link below:

RCA PS80690 Replacement Part Convergence Board

RCA PS80690 Replacement Part Convergence Amplifier Board (2F27039-502)


Please note, these boards are no longer available from the original manufacturer (RCA) and only appear to be available from PTS.

That repair only repairs the issue of the convergence option missing from the on screen menu. If thats what your problem is then the ITC222A convergence option missing repair kit at the following link should repair the issue. The kit contains the fl231, DL231, CL230 and the CD with detailed instructions.

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.

We replaced the transformer for our RCA F27650. It was sparking and now it is not, but now the screen won't turn on. It is just black. We hookd all the wires up like they were. we can hear sound, but...


Hello
Along with the flyback transofrmer, its horizontal output transistor also must be replaced. I don't know whether you have replaced it or not. If not, replace it too. It can be located very near to the flyback transformer, a three terminal component, black in colour, usually screwed to a metal heatsink. Then switch on the TV and measure the video output voltage at the video output card pluged directly to the picture tube neck. The collector of the video aoutput transistors must come around 145VDC. If it also is there, advance the screen control on the flyback transformer to get a raster. If that voltage is not there, it means that the flyback transformer is not working, and horizontal oscillator stage should be checked for oscillation, check the lined drive transformer for its primary winding open, Check the entire horizontal oscillator section. The collector point of the line drive transistor, the transistor that drives the line drive transformer, a small transformer soldered diretly to the printed circuit board; should be checked with frequency meter. The frequency at that point should come around 15525HZ approx: OK.

I have a 1993 36 inch RCA, model # P46151WK. TV was on and suddenly heard something pop and it started to smell like something burned inside. It wont turn on anymore.


You may have a fried horizontal output transistor and a defective flyback transformer. If indeed this set is 17 years old.......cheaper to replace him...sorry!

Turned on tv no picture only sound then i heard a pop and smelled burning tv turned itself off. 5 min tried turning on tv again nothing happened tv does not turn on at this time


Your RCA TV needs serious troubleshooting. Burning smell is from HV transformer or resistors smoking.

Most likely power supply and/or high voltage circuit or convergence circuit. Many times RCA have multiple or secondary faults that occur with HV or convergence failure.

Repair of RCA HV or convergence usually requires exact manufacturer parts and upgrades or repair in power supply. I would not advise trying this repair without manufacturer support for correct part numbers and service bulletins.

After replacing hv splitter and focus block and about four hours of adjusting the convergence board in the front I finally got a great picture, but now i notice when you have a title like on my dtv...


Is this set a RCA ? You may want to double check the seating of the Anode Lead from the HV Transformer to the HV Slitter, If pulled out
a little arching will occur with-in the Bock and cause premature failure if not corrected. Also make sure that all ground connctions are made from the CRTS to the HV Block if there are any.
Hope this Helps,

check Vertical IC out (LA78..) and resistor voltage supply from flyback transformer to this ic. Check the STR main power supply(and resistor near, change value), some times seems good out main board,but in operation not good

Blurry picture and arched at bottom


We have a Proscan 50" Projection TV. A T.V. repairman told us it was the HV (Horizontal Vertical) Splitter causing this problem and tried to find the part for us. The part for our TV was too hard to find though and we ended up not having ours fixed. Our T.V. is 8 years old though, and Proscan is discontinued. Maybe you'll have better luck finding an H.V. Splitter for your TV. Of course, you'd need a professional to install it for you. Good luck.
