Question about Hitachi 46F510 46" Projection HDTV

2 Answers

Dark , blurry picture

The picture on my 2 year old Hitachi 46F510 set has become dark and out of focus. I've got the brightness set at 100% and the contrast at 50%. This helps a little but the picture is still poor. The focus can be improved by setting the contrast lower, but this just makes the picture darker. The blurriness is especially evident during sporting events when the time/score is displayed or any time writing is in the picture. Auto focus is no help. This came on quite suddenly. Any ideas?

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

You will have to get a tech to look at your tv and replace the main board the brightness circuit is on the main board, and it will be cheaper to replace the main board.good luck.

My hitachi 46f510 picture is dark and blurry any suggestians


All 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.

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.

My 61" hitachi rear proj has a very dark picture.


It sounds that lamp in TV is weak and not throwing enough light to bright the screen for good image.
How old is this TV and did you replaced its Lamp recently?
If lamp has not been replaced yet or in last 2-3 years, replace it.

When you say you changed the focus block, did you adjust each color individually ? Most projection sets are adjusted by covering 2 lens and focusing each one seperately. Try this , it has always worked for me

Dark Color on TV. Can't adjust the color correctly


Having same problem now for a second time on a 57T500. First time was a bad green bulb that was covered under warranty. Only lasted 2 years....currently debating wether to fix or buy a new set. Bulbs cost about $300. Set is only 5 years old, so very dissapointed with quality.

Problems with brightness on the hitachi 50v810


Yes, they dim as they age, and you've done well to get 3 years out of one.
Projection TV makers charge an arm and a leg for their replacement lamps. They make it easy to do but as a result the custom lamp assy is expensive. The trick is to just buy the bulb for your model TV from any number of us aftermarket sources at a fraction of the lamp price and install it in the old lamp yourself. really easy.
