PLEASE BE CAREFUL WHEN DOING THIS PROCESS!!! YOU WILL DESTROY YOUR CIRCUIT BOARD LIKE I DID IF YOU DO NOT TAKE YOUR TIME OR ARE CAREFUL!!
What you need to do is clean the CRT coolant inside the TV. Here is a forum that I SHOULD have read before doing mine:

CRT COOLANT REPLACEMENT AND CLEANING

I was lazy and not taking my time to take care in not dripping any CRT coolant and some got on my circuit board, ( I felt confident since I had changed the Blue CRT 2 years prior) and I was only able to see about 1 hour of the best viewing my TV has ever given me since it was new, it looked like a miracle had happened. My TV was "dull" as the best way to describe it, colors faded, kinda fuzzy. I briefly researched into it again to refresh my memory then jumpted right into not really taking any precautions. I got lazy and didn't take out the CRT's like I did the first time with the Blue CRT and paid the price for it. Let me tell you, theirs nothing worse than getting a perfect brand new like picture only to loose it and hour later because of carelessness. Take out the CRT's, take your time, label everything and take pics, the reward is WELL worth it. Oh ya, you can use Mineral oil instead of the coolant that they sell at stores. Its not conductive, and dose'nt damage the circuit board if u spill a little. I used Baby Oil the first time I did it and when I went back to change the green CRT this time around it was still crystal clear, no discoloration in the Blue CRT I had done 2 years prior. I hope your results come out better than mine did!!

Picture seems very faded on tv it is approx 9 years old do they have main bulbs that can be replaced when picture starts to look washed out


If model number is correct the akai is a samsung; from the rear with the cover removed are three rather large black lens (one for each picture tube) that point upwards.

If the set has not been serviced for a long time clean the lens with a lens cloth or a paper towel with glass cleaner sprayed on it.

These are the light source for your picture and if dusty the picture will be darker and dull looking.

The picture is not clear. It has a red/greenish haze or gloss over the screen which distorts the sharpness. The manual controls do not help. What can I do?


If your TV looks 3D, warped, or distorted it likely has a convergenge problem.
If however it just looks dull, washed out, redish, greenish, or blueish or if it looks like objects on the screen have halos the fluid in the lens has soured.
You can search google for parts or you can get the parts with repair instructions from sites such as www.TvRepairKits.com

I have a AKAI projection TV. It is about 6-7 yrs old. The picture seems to be slipping down with a rainbox line at the top. Something is going out like the old days when a "picture tube" went...


Hi Scott,
Your convergence board gone bad. You may replace the Chip and other resistor around or buy online with the board replacement. If you want to do it yourself try the availability of the board on ebay.com or shopjimmy.com.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Double picture with red hue


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai2_bing.gif,Pioneer, Hitachi,Mitsubishi,Zenith and others.

Auto Focus Stoped Working


If the convergence is very far off the convergence ICs are bad and need to be replaced first. If the convergence is close and it wont correct it might just be an insect or some dust on the sensors at the 12, 3, 6 and 9 o'clock posistions behind the screen.
