Blue color tube damage

I have a hitachi 51f510 and the blue color tube had burned out, i had a repair guy come by and he told me $500 to fix the problem, he says he can either fix the tube i have, or replace it and then recalibrate my tv. Is there a cheaper solution? can i just buy the part and plug it in?

If you have had the set diagnosed by a technician, $500.00 for a picture tube repair and convergence alignment is not that bad.
Replacing the tube is most likely the best solution. Rebuilding a tube is something that can be done, but the tube has to be removed and sent off for rebuild, this can lead to a very lengthy repair.

I could not recommend that you replace the tube yourself.

If you are going to repair it yourself, there are some things to consider:

  1. The picture tubes are not as easy as some other components of a television, therefore they are not just a plug in affair.
  2. There is a high risk of electrical shock when dealing with picture tubes, as they will hold a charge like a capacitor. This charge is around 30,000 volts.
  3. The deflection yoke on the tube can be easily damaged during replacement.
  4. The focus and dynamic convergence can be difficult to do.
  5. If the set has scan velocity modulation, which I think this does. The SVM part of the tube has to be in the exact spot.

I hope this information allows you to resolve this issue.

My Hitachi 51f510 has no green adjustment. The lamp still works if i turn it up on the g2 block but I get lines across the screen that i dont get with the red and blue. I also cant see any text in green...


Please do us a favor and rate this solution after reading.

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.

53 inch projection tv...seems like the color red and color blue have shifted giving me a picture with red and blue shadows


For CRT projection TV's, this indicates that the Green picture tube is burned (warn out). The less green that strikes the screen, the more redish the image will look. You will need to find an old school TV repair shop that knows how to replace picture tubes.
In the case of a DLP style TV, the color wheel needs replacing.

Hitachi 51f510 Color problem


for testing, place the green crt board on the red crt and see if the red crt lights up and the green does not. If the green does not light up then check for 200+ volts on the collector or the output transistor. if you have that kind of voltage thee then check for an open resistor. If not then make sure the transistor is not shorted

COLOR SHADING


Sounds like a bad convergence circuit, unless you know how to use a meter and solder well you will need to call a reapir man. This repair should run you anywhere from $300-$500 depending on your area and the tech that comes out. If you were to do it yourself it would run less than $100. Please let me know if you need more info or would like to try it yourself.

Blue and Yellow shadows


Google "HItachi Convergence Circuit" and you will see that it is a very common problem. Looks like TV repair guys get $400 to fix it. The parts will set you back $15-$50 but there is some complicated soldering to do.

I am going to repair my own...but I have a lot of experience in soldering

Hitachi 50+in rear projection tv


If you mean that the 3 colors (reg, green and blue) suddenly no longer line up properly in one area of the screen, it means that one of your convergence IC's has burned out and needs to be replaced. There is no adjustment that will correct the picture in this case. When I do a housecall to replace a burned out convergence IC and realign the convergence circuits, I charge $150 but shops in your area will vary so be sure to ask around.
