AKAI PT5598HD - I HAVE REPLACED THE CONVERGENCE BOARD AND PICTURE AND SOUND ARE "ON" BUT "PERFECT FOCUS" WILL NOT BRING BLUE INTO FOCUS. "PF" STOPS AT 37% - RED AND GREEN PATTERS ARE SHARP BUT BLUE IS...


Most of these sets have a SCREEN/FOCUS block---usually all black with 6 controls----you need to look close at it as one row of 3 will be screen controls---don't touch those----the other 3 will be FOCUS- MARKED in little letters will be r,g,b(red,green blue). TWO ways to adjust the focus: 1. carefully locate the blue focus control and adjust to see if blue will improve in focus. 2. each of the 3 large lens where the picture comes out have a wing nut and a slot--you can loosen the nut and turn the lens---usually best focus that way is if the part that turns is in the middle of the available area to move it.

I should point out that all projection sets intentionally de focus the blue--the lines if blue should be clear but never as perfect as green or red--this is normal.

I do this here for free so if this has been helpful give me a vote here.

Adjust color, need service manual


On controlls the foucus...the other the brightness. I would not mess with them. 99% of the time the problems is one of the two listed below...

You have one of two problems. Sometimes both.

Problem #1) 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.

Problem #2)

Your TV may have a convergence 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 are some photos of convergence problems.

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 will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

HC R4755w Convergence adjustment


from the symptoms you describe it would apear that maybe one of your amps might be bad... However since you can move it one way then it might be a resistor bad. in convergence cuircit that would be my first choice.

Dark picture


use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.
