Horizontal lines when I turn on tv.PT-53X42 HDTV

When I turn on my tv which i have had since 2002 it has a bunch of horizontal lines(white lines) in the picture. If i leave the tv on for about 3hours the lines gradually go away.Is there a part i can get to fix this and install it my self? Or do I have to get a profesional to install it.

Get the professional, although this won't be an expensive fix... You likely have one or more caps in the vertical circuit that are going bad... A cap acts like a battery in a circuit taking on voltage and releasing it at an even rate. When they go bad their ESR (equivilent series resistance) rises and the cap takes longer to reach it's op temp and work properly...
A tech with an ESR meter will easily find and repair this one... But you'll need to take it in to save the pickup/delivery charges.
Good Luck!

The power light on my panasonic PT-53TW53 blinks 5 times in intervals. The TV set does not turn "on". Could you advise what this means ? Thank you for your help.

5 BLINKS means a short on the 140 volt line inside the set.

Usually this means the horizontal output transistor is shorted.

I can if you are able how to test for this and what to look for that may have caused this.

I am in California and online right now.

Come on then line horizal across screen then turs off

Horizontal line (up and down) is know as horizontal collapse. This is usually located around highvoltage section of the circuit. Because this circuit depends on certian frequencies and voltage protection circuitry will shut the set down. This will need a trained tv technician to fix this and can be expensive depending on the parts needed.

Horizontal lines

check all caps in power suppy and vertical. but i would point to the power supply first. the last tv i seen with this problem, i ran it for 20 minutes, and turned it off and felt the tops of all caps, found one or more that was hot. there was the bad caps, without the headache of checking all of them on the cap checker. this might not work for you. not all bad caps get hot.

Pink horizontal line when the tv is powered on.

1. White raster with no signal, washed out looking video with signal. Access the service menu, "menu 0357" use the audio button to select "video chroma" adjustments, use the video button to select item "40 - AGIW", use the adjust button to change the setting to 0, then press the enter button to store the change.

Horizontal lines when I first turn on my Pansonic 51" PT-51HW41 Projection TV

It's probably failing capacitors, does it squeal while this is happening?

Horizontal grey lines on TV

Sound like you have to turn down the G2 (screen)controls. They are turned up too high.
