Question about Panasonic PT-53WX54 53" Rear Projection HDTV

1 Answer

Help needed finding the impossible.

Hi guys. I'm looking for the colored chips that are inside of my projection unit. I have a Panasoninc model # PT-50LC14. I had a really bad green tint on the screen and after checking the set I decided to break down the projection unit. Sure enough there it was, my red\orange chip had the same shape that was on my screen. If you could help me it would be great. Thank you in advance for your time.

To much blue shade in picture


You may need to replace your STK chips in your convergence board. I just replaced mine due to ghosting. Seems to me asd anything that affects your picture quality is caused by bad STK chips. I purchased mine on ebay with a soldering iron solder and a solder ****** braid and paid 30.00 which includes shipping! Took less than an hour. The auction was for the STK392-010 but they had mentioned a 040 chip in the listing in error and sent me both sets. The STK392-040 is a better chip and works perfectly with my HC-P4752W. I had never soldered an electronic part in my life. I am an electrician and a plumber and master install tech. buy the chips. while they are being shipped to you, look at YOUTUBE for videos of soldering and desoldering using braid. You will get a good idea at what you need to do to fix tv! Also look for anything related to the convergence board for this model on YOUTUBE. Sorry so long but want to help as much as I can!

Sony tv projection colors distorted and it looks like 3d mode


what is model number? if it is a rear projection set with 3 lens inside-it sounds like you have bad convergence Ic chips--most of these sets use two IC chips---both need to be replaced and the set adjusted. If this is helpful I would appreciate a vote from you. If you need direct help email me model number.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together convergence repair kits for most models.

The kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, etc. Everything you will need to do the repair yourself.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.



You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

PINK AND GREEN COLORS ON BOTTOM OF PROJECTION TV


I'm not really sure on an exact fix for this, but I'm told that these are the symptoms of bad convergence module(s). My set is the same model no. and has the same symptoms. I was looking to see if I could find the exact part no. of the stk ic modules. I'm told that they are approximately $30 to $50 and are not impossible to change out if you have decent soldering skills. The normal repair charge seems to be about $600. Good luck. It looks as tho I may have to just give up and open the back and get the part no.s from the chips

Red color convergence


Looking from the back of the TV there are 2 large finned aluminum heat sinks just right of center. The chips are mounted on them. The one that you need to change is the one closest to you. It will be marked on the bottom side of the board with the letter " V " Unfortunately the chip and heat sink have to be removed at the same time because there is no room to loosen the chip in circuit. This job requires excellent soldering and de soldering skills. There are tiny surface mounted components near the pins of the chip that can be easily dammaged. You also need to check for any burned resistors or open pico fuses near the chip. Use original Sanyo IC`s no generics. Be liberal with the heat sink compound. Good luck and yes you are on the right track. One last note, just change only 1 chip not both unless you are unsure.
