Question about Akai PT5598HD 55" Rear Projection HDTV-Ready Television

1 Answer

Vertical lines If my TV is moved for any reason it will display wavy, vertical lines across the entire screen. Most of the time the picture looks this way, but sometimes it is very clear and crisp. I have checked all of the input connections and they appear to be solid.

Re: Vertical lines

The red line in the crt is the sreen voltage is to high or bad tube.
A simple fix is if you take off the front panel there will be a black box be careful it is high voltage make sure you are a pro.
there will be six controls look for the one marked screen and is for red tube adjust very slightly counter clockwise.until red
line gos away. If that does not fix it its the red tube.

I hope this helps doctor video

This is 1 of 2 problems. 1; Convergence(depending on the model of the TV, the convergence ic's will have cold solder joints) 2: vertical ic issues.

If they are different colored lines & the picture also bends, it's a convergence problem. Else suspect a vertical problem. In the case of vertical issues, most of the time it's a defective capacitor (or cold solder joints.).

If it's the 3-crt kind of big screen, it's possible for one of the tubes to be going bad.

It would be best to contact a pro to take a look on your TV and replace the defective components. This should not cost you too much.

Good luck!

About two months ago when we first turned on the TV there were wavy lines across the whole picture. When it warmed up they would go away. Now, the lines are there almost all the time and it's getting...

You are experiencing a lack of vertical deflection or vertical collapse. Since it will come back the first thing I would suspect is “ring cracks” in the solder joint in the vertical circuit, mainly the vertical IC. These suspect solder joint can be re-soldered and the television set repaired.
I would suggest that you contact a local servicer. If you are repairing the set yourself, be careful, there is always a risk of shock when dealing with electronics.
Check your equipment connections. Disconnect your equipment (VCR, DVD or set-top box) from the TV and reconnect, making sure each connection is in tight.

Sony KF50WE610 Vertical Blue Lines Across Screen

the vertical blue lines indicate some interference from other electronic gadgets near your tv. it started showing up on my sony grand wega when i installed my wireless modem. i almost ordered a new rear projection lamp costing over $100 but decided to experiment. i first moved my desk computer farther away from the tv then isolated the wireless modem router by placing it inside a small glass - the vertical blue lines became lighter in color so i dedided to find another small glass that fit inside the first glass container then put the router in the double glass - no more blue lines and my wireless modem router still works.
do some deductive thinking to figure out what's messing up your tv and isolate the interference.
good luck!
