20 Most Recent Akai PT4298HD Rear Projection Television - Page 3 Questions & Answers


Projection sets have two very common problems.

The first common problem is convergence


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,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

The most likely cause is shorted convergence chips and possibly a few pico fuses.

Hi Friend,
Please folliow the below steps one by one

Step 1: Turn on the TV

Step 2: Hold the ON/OFF Button for 10 to 20 Secs

Step 3:Without taking the hand from the ON/OFF button unplug the power cable connected to the wall outlet from the TV

Step 4:Without taking the hand from the ON/OFF button put the power cable back to the outlet

Step 5:Now take the hand from the ON/OFF Button and try to turn it ON again and check

If still you are having the same problem then please check the resolution configured in the Screen,try to reduce the Colour and the brightness of the TV

Even after that you are facing the same issue please check with the Display Card in the TV,

If you have any Clarification please feel free to contact us

Hi


Thanks for using FixYa. From what you have described it seems that you have to replace the convergence IC and check power resistor for leakage, if values are not exact you have to replace them. The typical cost to get this fixed by a pro is about $300 - and it doesn't mean that he/they will do a job better than you do. The parts are less than $100 (about $20-$30 for the IC's) if you want to do it yourself. Replacing only the IC's MAY solve the problem; however, many people have also had blown resistors requiring replacement. Why would you ask should you replace both of the IC's if only one is shot?! If one is shot the other one is not far away and for that little price of the chips it worth changing them both at the same time. Also the convergence board should be checked for cracked solder. If you replace the ICs and the resistors are shot, the ICs may blow again almost immediately, meaning you may have to do the repair twice. Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

It could be a couple of possibilites. It could be that the tv is set to sleep mode, or you could have the common flyback high-voltage transformer problem. That would need to be tested with a voltmeter to see if you have the same power output the main circuit board. There should be a label inside the set that says the DC voltage output. The voltmeter should match this rating as well.
