Throw the thing away! I have the same problem. can get no help from Sony...Technician says it is the light engine...cost: $1177.00 to fix. Foget it. Old saying "Sony-No-Balogna" New saying "Sony-is-a-Bunch of Balogna. Would never suggest a Sony product to anyone.
Aways had RCA's...each lasted at least 10 yrs with no problem. I have had this set for only 21/2 years.
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'
well, this didnt really work for me but its worth a try...try unhooking everything from the tv and let it rest for a bit then...then try re-setting it...i was told the re-set code for this tv is mute-182-power...hope it helps!
sounds like you might have the hypermodule capacitor problem. there is a cuircit board in this set that has 11 very very small capacitors that go bad this is charistic of wavey lines that go away after warming up. and eventally not going away. we repair about 2 of these a month at our shop. we would loved to just replace the board but this board is not availble we cant find it. so we very carefully resolder these caps. with magnifers and twezzers. so i dont recomend anybody attempt this except experience technician., you can easly damage this board and once damaged u cant find the board.
This is the same problem as other posts have mentioned about the right side of the screen having a bluish-balck stripe down the side of the screen. Here's what's happening. There's a small light tunnel which has 4 very small mirrors located just behind the color wheel. The lamp shines light through the color wheel as it turns and the light goes through this small tunnel and is then relected off several mirrors before it is projected through the lens and onto the screen. Optoma apparently did not use a very good heat resistant expoxy glue when they assembled these mirrors and over time the mirrors drop down causing a shadow effect on the screen. It can be repaired without paying some repair shop a small fortune. Previous posts have a solution from another contributer whihc includes photos. I had to repair mine and it's worked fine since I used a decent expoxy to hold the mirrors.
