Panasonic PT-53TW53 53" Rear Projection HDTV-Ready Television - Answered Questions & Fixed issues

No I have not read of any other issues like this.

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

I have this same issue. Did you ever figure out what was going wrong and how to fix it?

Easy fix. I had the same green dot problem and I removed the front panel (no screws). In the center is a panel that has two screws. Remove them and pull the cover off. There you will find the projection bulb. Do not clean the bulb but instead the base. Use a damp cloth to wipe the dust off the black disk (the base of the projection bulb housing). Apparently the dust through static electricity may cause enough magnetism to distort your picture. Hope this helps.

This is a very common failure on Projection TV sets.

• Screen looks 3D
• Colors don't line up
• One or more colors can't be adjusted when using the convergence menu.
• Screen is bowed or warped.

You can see some example photos and find a solution here...

That board will be hard to find. But the power indicator should blink a series of blinks when it doesnt power up the number of blinks will indicate where the problem is thats preventing the set from powering up. If you let me know the number of blinks I will assist with the problem.

my tv panasonic PT-53TW53G turn on red light on tv no pictur on sound

If none of the connections on the set work look for a menu on the unit in the owner manual for the PS3---it may be a selectable setting in that that is causing this problem--also try the PS3 on another set to make sure it is ok.

Have set not work and power light blinks 3 times?

Your part# for the lenticular screen is TKG2AH50641. Panasonic has them new for $358.65 plus shipping. Or you might be able to find one cheaper if you google it or find someone that has the same model TV that doesn't work anymore.

if it is the model listed here pt53w53 the lens on the three tubes may require cleaning, a fairly easy process===with set unplugged remove back cover and clean the three large lens you see at the top--glass cleaner sprayed on a paper towel is fine or a lens cloth will do.

It looks more like an open solder because you were able to align it properly after replacing the STK ICs, if there was an open resistor(s) you would not be able to get it align.
I would suggest to go back and double check the solder joints on the STK ICs as well add some fresh solder to the resistors nearby the stk392-180.
Good Luck.

Need to see if you're getting high voltage. See if you have 130v dc on the collector of the horizontal output transistor.

I would say between $150 to max $200. When this guy fails its due to other components in the vicinity, have a pro do it.

First I know this set well, did you pull out the board or the light box to replace the chips?Convergence problems are usually easy to see...see attached photos and tell me as much as possible.SD TECH

this and a few other related models have a common problem; C509 on the deflection board fails, if it opens you will have a picture that closes until you just have a faint band of light to the right of the middle of the screen; if it shorts then the sweep transistor will be shorted and usually you will have nothing.C509 is brown in color and located near the yoke plugs----some will fail and that cap will have a crack in it. I have seen several where it opened and got the output transistor at the same time. If the output was still good you would have sound like I think you did in the beginning.If you have a multi-meter (ohms etc) check the output transistor from center pin to the outer ones---no reading from center pin to other two.I do not know you skill level.SD TECH

Hi,
To adjust the convergence propely you need the orginal remote of the tv. Even though you can select all functions using an univeral remote when you enter in to the convergance service menu the proprer command can sent only with the orginal remote (also recommended by the manufacturer) . As it is receiving signals there is no problem with the tv's remote sensor. Only thing is you need its orginal remote. You can find the orginal remote for your tv in the following link.

OK

5 blinks is a short on the 140 volt line inside the set; most likely is the Horz. sweep transistor is shorted and possible also is a cap in same area.

If you have a meter to measure resistance with the set unplugged I can tell you how to confirm this.

Before you rate this information let me know if you have a meter and such.

Yes, it has a bad capacitor on the D board and it will usually be easy to find as this will have a crack in it.

There is an easy and a hard way to approach this and I need to know which you want....
