SOURCE: ?Convergence problem

Sounds like the convergence IC'S are either bad or a fuse maybe bad in the convergence circuit. The part # should be on the chip itself if you want to try and change them yourself. Good luck and keep me up to date on outcome. Cheers. Jay

SOURCE: i have a rca r52wh74

The 45 volts feeding the convergence amp power supply may be missing that is why convergenc is bad the heat sinks on the convergence amp cba are probably cold from not running that is why convergence is not displayed in the menu repairing the power supply will most likey fix it for you I assume you have a schmatic?

SOURCE: RCA model P61950

fl231 is the convergence fuse, and is soldered to the board in proximity of the convergence ICS, on RCA rear projection TVs.


If
fl231 has blown, TV usually does not turn on at al, if you get bowed picture, that means that the convergence ICs must be replaced.

The fuse is on the same board where you find convergence ICs, if the fuse had blown, or the pico fuses at the base of the STK convergence ics had blown, the STKs must be replaced.
There is need of purchasing the service manual to do the job.

The repair shuld be done by a technician.

This is the convergence IC, model may vary:

you have lost convergence. First thing to check is to see if you are missing the convergence option in the customer setup menu. if you do not have this option then i suggest reading the article in the tips and tricks section entiltled "the fl231 fuse problem" this is a common and sometime easy repair if you do have it then you might need a convergence power board

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com.

Colors seperating and Screen bowing


The convergence circuit is not working. There are bad solder connections on the sweep board and a small fuse is open. this is not easily done yourself unless you have a technical background but an RCA tech can fix this easily.
