Question about Televison & Video

RCA r52wh74 My screen now looks like a 3d movie with out the glasses. A technician came out an told me it was my power converter and wanted $300 to fix. If I can find some where to buy the part I can do it myself. Where can UI locate a parts break down for this model I have the same 3d thing going on. I was trying to figure out where in the back of the TV this part is located. I had the extended warrenty on my TV....but Smart Plan doesn't have anyone to send to fix it in my area. If I can fix it myself..that would be great! I looked in the back of the TV and don't immediately see anything that looks like the part you referenced for the other person-- STK392-150. Can you tell me where it is located on this RCA model R52wh74? Thanks!!!

    Part of the post that I sent included some of the posting that I was reading when I replied...not sure how that happened. I didnt get anyone to come out here because like I said...Smart Plan didnt have anyone that could come and fix my TV even though I had the extended warrenty. But it sounds like its not possible for me to fix on my own. I have never soldered anything in my life :) I just thought it might be something that plugs into the tv's guts somehwere that I could replace myself.

Hi the problem you are having is a common one dont know what the repair bloke told you but your problem is with the convergance ic their are two of them located inside your telly the are located on two metal heatsinks sticking up out of the board the parts start with stk they might have a clip round them holfing them onto the heatsink these need removing to see the part number.
When you get the part number google it and it will locate the people who sells them part numbers for you these parts are not user repairable they should only be replaces by a pro as when you solder them in you cant let them overhear as this will blow the ics again but if you are confident in doing the repair then you will need a multimeter as well to check any resistors that might have also blown ok if you need further assistance let me know ok

    Oh just one more thing if you cant locate the part inside your telly then you will need to download the schematics so use something like and type in
    schematics for then give make and model number this should then locate the schematics for you the schem will also give you test points on the circuit board to test for any faults so have a look for this ok this should be what you locate first as following the schematics will save you loads of time locating the faults

    H no these parts need soldering and if you dont disperse the heat from the solder you could blow the chips whilst soldering them in so its best left to someone who has done this before

How can i convert 3d split screen to half sbs so i can watch 3d movies on my soniq E55S148 3d tv

I would suggest you know what you're talking about first
SBS means side by side It's not 3D SBS is a format to be used in conjunction with virtual reality headset/ goggles
If its HSSBS half screen side by side that you mean then that is for viewing on a small hand held device and you still need the VR goggles
So if you are downloading actual SBS you can't split it
If its HSSBS the file is too compressed to view on a TV
If its 3D format you need a 3D TV and use the 3D glasses
You can however use software to convert SBS to 3D format whilst its stored on the device you downloaded it to but when you play it on any TV it will have no 3d effect even with glasses
So until you sort out if its SBS or 3D you haven't got a hope
split screen 3d or simul view is only really meant to support two player games
More importantly you shouldn't have been such a cheapskate and invested in a proper TV Soniq uses a mix of branded and Chinese components that aren't 100% compatible so no amount of add ons ?or software upgrade will convert that piece of junk to anything that is capable of playing SBS HSSBS or 3D
If you want good quality adult movies you should pay to join a reputable site but if you choose to download pirated p?r? you can only expect to get what you pay for
My question for you is if you wanted to watch SBS why did you download in 3D and then want to convert back to a format that is not 3D?

Convergence box is out - the picture is like looking at a 3D movie without the glasses.

There are two common problems with these sets.

Problem #1) Convergence

  • Screen Looks 3D
  • Colors wont align
  • Video may look distorted
Problem #2 CRT Fluid has clouded over. Symtoms
  • Dull looking video
  • White looking video
  • Halos around objects
  • Red/Orange looking video

You can see some examples and find a fix here...

Screen showing lots of colors caving in on top

You have no power to your convergence circuit. Depending on what model RCA you have will determine which parts are bad. Will cost about $200-$300 for a repair shop to repair.

Picture looks like 3D without 3D glasses on???

The cost I don't know, but this can be fixed. I'd say shop around a bit. Make sure the repair person is certified for your TV's manufacturer. There are generally 3 lamps in projection T.V.'s, Red, Green, and Blue. They have to be aligned for the TV to project a clear picture. A credible TV repairman should be able to fix it. Depending on if it's new enough to be under warranty they may cover it as well. Really the only reason to get rid of it is if you want to get a new TV anyway. Depends on the cost of having the lamps aligned.

Sounds like a convergence IC issue. are the red and blue colors out of alignment making it look like 3 images? If so you need new Convergence ICs. You wil need two of them they cost about 10.00 each They are STK394-040 you can get them at the following link. It shows a picture of your ICs
If you need anything further please let me know.
