Question about Pioneer SD-533HD5 53" Rear Projection HDTV

1 Answer

Hourglass Picture I replaced two STK392-110 ICs on the convergence board and I now have an hourglass picture. You answered the same problem on another Pioneer model by saying to check for open fusible resistors. I do have a Pdf Manual ARP3094 but fusible resistors are not identified as such. Could you please tell the resistor numbers, values, and locations? The page numbers in my manual are from 58 to 63. If you have any other suggestions I am all ears. Thank you kindly for any help you can give.

It easy to locate the fusible resistor in the power module PCB,it look like a resistor but white in color,normally printed soc xxxx (2100) on top of the component. After you replaced the STK392-110 , you need to re-alight the convergence setting again.hope it will help.

Sony 53 inch projection screen with hourglass picture

If you are familiar with TV repair, have electronics basic knowledge, good soldering skills and tools then check dry (cold) soldering joints at D board of this TV. Resold all lose connections there and check picture.
Still no joy then you need to replace D board.

Have you ever had this problem?

Sorry Ginko, but a convergence problem would have the curves down from the top and up from the bottom. The hourglass shape is a pincushion problem. This can be as simple as a bad capacitor in the pincushion circuit.

Could you please confirm the model number so I can look up the probable part?

Thanks,
Dan

Red sideways hourglass

Your TV most likely has one of two possible problems.

Problem #1: Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.

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 need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.


Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

Magnavox 51mp392h

replace the convergence ICs STK392-120 you will need both of them also check the 6.8 ohm resistors right next to the ICs as often 1 or 2 of them burn open. You should be able to notice the discoloration in the center of the resistors.

Hourglass screen

Did you check for fuseable resistors open when you changed the chips? This usually happens on a pioneer set . Did you get a manual?? You shount try to fix a set without a service manual. i'll see if I can get the way to do it BUT your still going to need to find those fuseable resistors thats bad. A manual makes it alot easyer. Good Luck
