Question about Hitachi 61SDX01B 61" Rear Projection Television

1 Answer

Keep repairing a 8 yr old TV

This will be the third time, I've had a repair man come out and fix a convergence circuit failure on my Hitachi 61 inch projection tv.
Is it worth paying to have this same problem fixed or should I purchase a new set?

If the TV still has a good picture then yes. Have the Tech replace the IC's with the Sanyo Type as they are a better quality IC. They cost about $30 each as opposed to the generic for $10 each. He should also make sure there are no resistors in the circuit that may have changed value.This could cause the IC's to go bad prematurely.

Picture is off the top of the screen everytime it is turned on. If you turn it on and off several times(3-13) it will become watchable. Sometimes it is off the bottom, or both sides are concave. Or it will...


Its a rather old set to be fixing, if off at top or bottom=vertical deflection problem, if sides are concave pin amp circuit---the fact you can turn it on/off several times etc suggests to me maybe bad solder connections somewhere in those circuits.

AS old as this set is keep in mind a lot of the parts for it are no longer available so be careful about spending a ton of money to fix it.

IS it worth fixing a 7 yr old tv with convergence problems?


Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both. Repair kits with instructions are also avail from www.TvRepairKits.com

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....

  • 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.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

Common 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.

I'm getting an overlapping of two colors on the screen.


Hi,
It is common problem with rear projection tv and 3D type picture problem occurs due to failure of convergence output ICs, replacement of convergence output ICs will fix the issue and tv will again show correct converge picture as before.
Let me know tv model number written on back of tv if you want to fix tv by yourself as it needs soldering parts in circuit board expertise and if you feel uncomfortable working in tv circuit boards than local tv repairman will do this job for you.
Thanks.

All color guns out of alignment


Needs convergence amps replaced. Sometimes resistors burn and need to be replaced. This repair requires soldering/desoldering equip. and a trained eye, but usually can be done for 175.00-325.00 at a reputable service center. Good luck, Russmann.
