Question about RCA R56WH76 Projection Television

1 Answer

RCA R56WH78 No sound or video

Hey I have a RCA R56WH78 that recently took a turn for the worse. I had to open it up to show a friend where the FL 231 fuse was and how to get to it,and when I went to turn the TV back on the power would go but nothing else!!! I saw a similar post and they said to check the capacitor cp150, I checked and it didn't look broken but I don't think I know how to tell that well. can someone help?

There are 3 fuses by the flyback,check them.also look for bad connections under flyback-also check for a bad connection on the crytical safety cap.if all else fails deflection board part number is 272074,NTA thru rca but tristate module or pts electronics can repair it for you.

Hello I read ur answer to the Fl 231 fuse problem in rca projection tvs. I have...


FL231. FUSE.... The RCA ITC222 chasis has a common problem. and it not all that difficult to repair. Does your rca projection tv have read blue and green shadows? Does it have bowing in affect on the top and bottom of picture? when you turn it on does some thin red green and blue line bow in from the top then go away. The main question to determine if you have the fl231 fuse problem is if you go into customer menu then setup do you have the "CONVERGENCE' option. If you do not. then i suspect you have this problem. In the manufactering of these sets Lead free solder is used. now there is great debate over the use of lead free. connection tend to be more brittle. cracks develop around the solder connections of the high voltage flyback transformer. this very small crack set up oscillations in the cuicit with a 400 milliamp fuse. THis fuse cant take it. When this fuse blows the processor then does not know its a projection tv with three projection tubes. it thinks its a crt tube tv. and crt tube tv dont need "convergence" so it removes the convergence from the set.

TO REPAIR... 1. Warning. this set can generate leathal dangerous voltages even unplug do not attempt if you have no experence with electronics.
2. Remove the back. there a number of torx 20 screws.
3. what you will see is a number of circit boards There will be one on the right and one on the left. the one on the right is the small signal board. the one on the left is called the power deflection board. it has a large black part with a big red or black wire coming from the top, this is the flyback.Next to the flyback on the right of it there will be three small rectangular componets tan or brown in color. these are fuses. the one in the middle is the fl231 fuse.
4. getting to this fuse can be difficult. these two cuicit boards sit on a tray that is removable. to remove this tray it is pulled out and up. BUt watch the wires.loosen the wire tyes.
5 when you get the tray up the bottom side of the board can be accessed
you will now have to unsolder that fuse. one side of this fuse is under a plastic part of the tray. i have found the easest way is to cut away the plastic to get to it. if you dont want to do this you will have to remove the board. only remove half of the plastic brace
6. REPLACE FUSE RCA PART 259213
7 RESOLDER FLYBACK CONNECTIONS simply heat up and add a little solder
8 reassemble set. make sure you examine the set for loose connections.
9 and remember "BE Careful'

I cant find where to go to find the convergence option.. the manuel say's its under setup but on my tv thats not an option as it states in the pic can anyone tell me how to get in to convergence threw my...


That's a common problem with that model the auto convergence option would disappear from the setup menu. But it's a very easy and inexpensive repair that you can do yourself. You can get the RCA repair kit called the ITC 222 and ITC 222 A chassis convergence option missing repair kit. The kit contains the FL 231, DL 231, CL 030 and also has repair instructions on CD. Is $25 from www.tvrepairworld.com listed under their RCA repair kit category.

sounds like you have more problems than just the fuse.. did you resolder the connection when you replaced the fuse. this is what causes that to happen.. fuses blown for a reason. ussally something is shorted. that particular fuse blows because it is a very small fuse and doesent take spikes in power to well. so when a intermittant connection begins to cause ossillations it shakes that poor fuse. it however sounds like you have more than that. does the led on the front flash when it shuts down.
