SOURCE: Dark , blurry picture

MTNESTR, My guess would be the FBT loc.TH01(flyback transformer) Hitachi p/n#BW03004 which would be far less expensive than replacing the entire deflection board... A shop could ring test the FBT to confirm the failure. I do know the FBT in this unit has an internal resistor that is prone to failure. It is in-line with the focus block and if it's open it would explain the blur and lack of screen voltage to light the crts properly. The deflection board is about $290-$350 plus shipping and a FBT is somewhere between $60 - $90 depending on the supplier. Hope this helps! Bill

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.

The kit comes with original Sanyo STK IC’S , not those cheap aftermarket or china made IC’S full pictorial directions, the thermal paste, resistors, the correct Pico fuses, AND free live on-Line tech assistance in case you run into a problem with the repair. They ship out 2 to 3 day Priority mail, the next day in most cases GOOD LUCK!!!

Blurry screen


I have researched your set. There isn't a date of production that is available so your guesstimate of 11 years old is about where I would place it.

For your specific problem (which is common among old style projection TVs) it's usually the three picture tube or "guns" are showing their age. If it has slowly become more blurry then that is the case. If it has suddenly become blurry then there may be a fixable defect. Judging by it's age I would suspect that your are up for replacing all three tubes in your set. My recommendation is DON'T DO IT. You will be much better off purchasing a newer and preferably flat screen TV. All projection TVs with picture tubes in them typically last between 10,000 and 20,000 hours of operation. At 11 years your set is in that range if you watch an average amount of TV. Enjoy looking for a new set and pick out something that tickles your fancy. Sets have improved vastly with the thin screen technology.

TV wont stay on


Sounds like a short somewhere in there. I see old pre-HD big screen sets going for well under $200 on my local craigslist, so look there for a good replacement, because the repair will cost more.

Or fork over about $500 for a good used HD projection set.

Hitachi-picture goes out but can still have sound


If it is a Hitachi 60V500 LCD projection TV, then I would suspect the lamp being the problem.
