Question about Panasonic PT-53TW53 53" Rear Projection HDTV-Ready Television

2 Answers

Where can we get the best IC Replacement

We have the Panasonic PT-56TW53 and it's IC's went. I have been reading mix reports about which IC's to get.

I went to the Parts Store, but they seem to be made by Panasonic or at least that is what it states when we look up our model. They do offer Toshiba brand.

Do we go with the Panasonic Brand or do we opt for another brand? We don't want the same thing to happen again so soon, so we are reluctant to get the Panasonic Brand.

If someone has done this replacement and can offer any advice as to where and what brand to purchase, I would be thankful. Any help or advice will be greatly appreciated.

This unit used STK392-110 ICs. THese can be purchased from any reputable supplier. I have used Toshiba, Sanken and others without problems for years. When you install them, make sure that you also use plenty of heat sink compound (white stuff) on the back between the IC and the heat sink. This will insure good heat transfer and make the ICs last longer. Also check the area for any low valued resistors that may have changed values or opened up.

Always stick with the manufacturers brand ! but you will need to check the resistors on the IC lines to make sure thier values are not off , because that will cause the IC to go again no matter what brand IC you use. other components in line of the IC should also be checked for bad values as they can also cause malfunction and breakdown of an IC and its circuit components

Pt 56tw53 picture trouble


Based upon your description, the problem area is the convergence circuit. These sets usually have a couple of large black ICs that control the convergence. These Ics either have bad connections on the pins or are failing. You can try resoldering the pins of these ICs if you can solder, or replace them. These ICs are usually marked STKxxx and are attached to a heatsink.
If you get this repaired, expect to pay about $30-$40 for each IC (there can be 2) along with the local labor rate for projection sets.

Screen went black with a vertical rainbow line down the middle


Failue of the vertical section, could be the drive, the power to the section or even some discrete componets. Unless you are familiar with electronics , get some help to ceck out on these circuits, could not be major but to get themain culprit will require good probing.

My panasonic pt-56tw53 picture was not looking righ all on adjusted - went to the converge set up and now lost whole picture just shows all colors in middle on tv zig zaging


If you go into the customer menu and select convergence and it is skewed you need to remove the light box and replace both of the STK-392-110 CONVERGENCE IC chips this set uses.

I HAVE START TO FINISH, STEP BY STEP INSTRUCTIONS FOR THIS REPAIR IN THIS SET--I can post them here if you think you or someone you know can do the repair.

Most shops get 300 or more for this repair--if you buy the chips on Ebay (I can tell you the seller to look for there) they and any other parts should total under 30 dollars. The fact that the set is still coming on means most likely just the two chips need to be replaced and the set adjusted with the Panasonic remote for this set.

If you have questions or want the instructions rate this solution and let me know and I will post them here---I do this here for FREE.
