My picture is warped or bending in the middle


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. 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, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

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

Problem #1) Convergence

Yours may have one or more of the following symptoms
  • Screen Looks 3-D
  • Colors wont align
  • Screen may look distorted or warped
  • No Audio/Video - makes a chirping sound.
Problem #2

Another common problem is dull or washed out video.
Your TV may have one or more of the following symptoms....
  • Dull looking picture
  • White looking picture
  • Halos around objects
  • Red/Orange looking picture

You can see some more examples and find a fix here

Akai lct2701td, flat screen tv won't turn on.


Oh Dear. I had the same problem!! The Akai televisons are not well engineered-meaning that they tried to put too much in a little package. The problem is that the power supply is malfunctioning"supposedly". But I believe that the sad truth is that the whole motherboard is malfunctioning. I can suggest a few TEMPORARY solutions but they too are not guaranteed to work!
1. Bring the tv to a repair shop and tell them to check the power supply. If it is faulty -have it exchanged and it will work for <2 weeks.
2. Literally "bend" the television in multiple directions to find a sweet spot where the screen turns on.( wait for the diode tu tur green before doing this) this will slightly bend the motherboard in hopes of agitating it to turn the screen/bulbs on.

I am terribly sorry that you too have this ridiculous problem!!!!!! :-(
Good Luck!!! I am crossing my fingers for you!!

Can not connect cable to TV


Well I have the same problem and I have been looking for an adapter for quite a while now and cant find anything... So i ended up cutting the end off my coax cable being careful not to strip off the outer wires( just like I was going to put a new end on it) leaving the middle wire about 1 1/4" long (enough to bend it in half) then I shoved the middle wire into the middle hole of the rf input and wrapped the outer silver wire around the outside and ran electrical tape around the whole thing so it wouldn't ground itself out and I'm picking up the channels perfectly. Hope this helps

Perhpas the TV has a timer function that is turning it on at a certain time. Does it seem to occuring at the same time of night? check the TV settings for a timer.

The only other possibility is that the camper is losing AC power in the middle of the night, and when the power comes back on perhaps the TV is turning on.

However, i rather suspect the first problem...

I am a certified RV technician, so if you have other problems with your camper please let me know

Panasonic PT-53WX53 fast horizontal scroll


Replace Ic7001 and Ic7002 the convergence amps in this unit. Both are STK392-110 Sanyo built Ic's and fairly inexpensive. If you're not at all sure how to replace these take it to a qualified shop. And when you're calling around shopping ask what they charge to replace the convergence amps in these units.
Also take the unit to them rather than pay the pickup and delivery charge, that will save a few bucks.
Have a great day!

SONY KP-61HS30


When one or all the colors are bending severly, then the convergence circuit is not functioning correctly and must be repaired. Only one color bending means just the convergence ICs and all colors bending means convergence ICs and voltage supplies. Convergence issues are the most common problem with rear projection (w/picture tubes) televisions. The cure is replacing the convergence IC's. Sometimes the pico fuses need replaced as well. If you have the experience to use a soldering iron and a basic understanding of electronics, then, you may be able to do this job. If not then call a servicer in your area. Go to the Sony website, Sony.com, and you can locate one in your area.
