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

12 Answers

Tried having the ic's replaced but still doesn't work

I had the ic's and resistors all replaced but I think they burned the board in a couple of spots where the ic pins go in. Is there a way to fix this or do I need a new board?

    How expensive would it be and where can I get a new board?

  • LEEBEE72 Aug 21, 2008

    My tv model# is pt 53wx53g Panasonic and the board is tnp2ah046.

  • LEEBEE72 Aug 21, 2008

    where can i get the board and is there a different board that can be used if I can not find the one I already have?

  • LEEBEE72 Aug 21, 2008

    There are certain spots that the solder won't even stick to the board I belive because of how it is burned. Is there still a way to fix this

  • LEEBEE72 Aug 21, 2008

    Anywhere else that may have the boards?

  • LEEBEE72 Aug 21, 2008

    Anywhere else?

  • LEEBEE72 Aug 21, 2008

    I can not get a picture but the burning is so bad that the solder will not stick to the board.

  • LEEBEE72 Aug 21, 2008

    fixmymonitor.com doesn't have parts.

  • LEEBEE72 Aug 21, 2008

    why do I need a professional?Is the board to hard to replace?

  • LEEBEE72 Aug 21, 2008

    can't find it on tradekey because I'm not sur if I was in the right section

  • LEEBEE72 Aug 21, 2008

    Is the board hard for a non professional to put in?

  • LEEBEE72 Aug 21, 2008

    Can I install the board myself or is it difficult to do?Does anyone have any instructions on how to do it or tips?

  • LEEBEE72 Aug 21, 2008

    The panasonic link you gave me says I need to request access for the online store.

  • LEEBEE72 Aug 21, 2008

    I replaced the ic's and all the resistors but it still blinks 3 times and so I replaced the ic's again and noticed where some of the solder didn't stick to the pin holes because I believe it was burned.

  • LEEBEE72 Aug 21, 2008

    It looks like all you have to do is unplug all the wires and unscrew the board.Is there more to it?

  • LEEBEE72 Aug 21, 2008

    Thats what I figured and I thought there has to be a way to repair but how do you do it?I've seen kits online but is that what I need?

  • LEEBEE72 Aug 21, 2008

    The link you gave me for cmpalmer says it doesn't exist.

  • LEEBEE72 Aug 21, 2008

    Thanks I got link

  • LEEBEE72 Aug 21, 2008

    Thanks I got link

  • LEEBEE72 Aug 21, 2008

    Thanks I got link

  • LEEBEE72 Aug 21, 2008

    Got the link and that is what we did but it still blinks 3 times so I figured it was becasue of the burned pin holes.

  • LEEBEE72 Aug 21, 2008

    Well the first time I did not do it but I had stk392-150 installed as per someone on this site.But it blinked 3 times so I removed them and asked for more advice and was told to use stk392-120 and to replace all the resistors so I did.

  • LEEBEE72 Aug 27, 2008

    yes it is only 3 blinking lights,no picture or sound because it turns off after it blinks.

  • LEEBEE72 Sep 14, 2008

    where can I get the board and how do you replace it?

If the pads are charred, then it becomes a bit more challenging to do the repair specially if you only done basic hand soldering.
Click here to see a short video on how to fix the broken pads or conductors.
See the last video titled: Plated Through Hole Repairs of PCBs, since the holes are already there ignore the drilling part but pay attention to the rest. From this point on, you will know if you want to attempt to repair it, buy a new one or send out for the broken pads repair.
I would estimate that a broken pads repair could be 1/3 of what a new board will cost.

Depending upon how much burning has occurred, the boards can be repaired. This is not a homeowner project though. I have repaired numerous boards in the last 20+ years. The charring itself should not be a major problem unless severe. CAn you post a picture of the area? Most shops won't do this type of repair. Only a few of us do this any more. Most shops don't even provide component level repairs, just board changes. Post the picture and your general location and I'll try to recommend a repair location for you.

    It sounds like the board "traces" are gone. This can still be repaired. That board is no longer available. Your only recourse is to have the module repaired.



    Dan

  • ABRsvcs Aug 21, 2008

    Any repair kit will only include replacement parts. These kits assume that hte PC board itself is fine.



    Dan

  • ABRsvcs Aug 21, 2008

    The 120s and 150s are pin compatible. The 150s can take more power so they would have been OK too. If changing these ICs did not resolve the problem, then we need to look elsewhere. Is the only symptom the 3 blinks of the standby light along with no picture? Is there sound?



    Thanks,

    Dan

  • ABRsvcs Sep 15, 2008

    Let me state this again as you may have missed it in the amount of garbage included here as solutions.



    The board you need is NO LONGER AVAILABLE as as assembly. There is a repair kit which will contain all of hte parts that usually get fried when the ICs fail. Based upon your descriptions here, either the board has some broken/charred traces or the power supply (another board) has some problems. At this point, it is unlikely that this problem will be resolved remotely. You will need to see a servicer. A look inside the set and measurements throughout the set need to be made to locate the problem and resolve it.



    Hope this helps,

    Dan

PC boards they are called have gold lines on them that serve as wires. If some spots are burned then the current will not pass through then that means that it will not work. You will need to change the board unfortunately. Although you might try a cleaning solution such as alcohol to clean off the burn marks and hope they work.

Hi


Thanks for using FixYa. Heat is the number one enemy of electronics, and these sets operate hot. This problem is caused by the power supply being overloaded. This is often caused by failed convergence ICs. I don’t think the issue is with the power supply of the unit as the sound is coming fine from the unit. This model of TV has over 3,000 parts which include millions of transistors inside the integrated circuits. Over time the capacitors will change value, leak and become defective. Resistors will change value and burn. This will cause other components to become defective. This can has a domino effect and cause other parts to fail. Replacing one defective part may make the TV operate for a short time but the part will fail again since if the parts that caused the failure to begin with are not replaced. The typical cost to get this fixed by a pro is about $300 - and it doesn't mean that he/they will do a job better than you do. The parts are less than $100 (about $20-$30 for the IC's) if you want to do it yourself. Replacing only the IC's MAY solve the problem; however, many people have also had blown resistors requiring replacement. Why would you ask should you replace both of the IC's if only one is shot?! If one is shot the other one is not far away and for that little price of the chips it worth changing them both at the same time. Also the convergence board should be checked for cracked solder. If you replace the ICs and the resistors are shot, the ICs may blow again almost immediately, meaning you may have to do the repair twice.


Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

Have a philips magnavox 8p6044 c102


Hmmm... I dont know where to find those CTR Circuit boards I'll post my general post for you about what I know it has links to the manual and some other sites it may help.

how bad is it burned, did some chips go or just the copper circuit board tracers. you can use circuit board wire and solder it from point to point,
I had somewhat of the same problem with my IC board, I had a bad portion of the board where I had to build a new copper routing with circuit wire, the copper burned off when the resistor failed, you may need to do a little Frankenstein work on your board as a last resort... remember use a low 15 watt soldering pencil, use leaded solder, and USE flux!
however with all my work, I got it running but the IC board is still not running perfect. if you decide you cant fix the TV I would love to buy your IC convergence board from you.
GOOD LUCK! hope I helped...
GENERAL POST WITH LINKS BELOW.....
51MP392H/17

Actually I have this TV and you need 2 Convergence IC's STK392-120's (120's and 150's will work) of course order 2 of the same type I'm using replacement 150's they allow for a little higher heat and were cheaper ALSO you need to replace the 12 resistors with 6.8 ohm metal film resistors, make sure they are metal film! don’t skimp out here I did and then they blew and fried my IC's and I had to replace everything again!

Great reference link that I posted pictures on, check out page 3

Where I got all my parts that worked:
Suburban Electronics http://www.suburban-elect.com/

Manual Library you should find all you need here:

What you need:
(2) STK392-120 OR STK392-150 IC chips
(12) 6.8 Ohm Metal Film resistors
set of star screw drivers
15 watt pencil solder pencil, DO NOT use a high watt iron you will fry the surface mounted item.
good leaded solder, and flux


BTW if you don’t plan on trying this and are going to throw out the TV, I still need a IC convergence board for a 51MP392H/17 TV I'm fixing, I'm willing to pay S/H and buy your IC board that’s not been tampered with. Edwinkraus@hotmail.com

Philips convergence


The convergence ICs are what cause those resistors to fry, But its possible that others are also burned without any outward signs. They have to be checked by lifting one side of the resistors out of circuit.

Problems after new ic chip install


Did you check for open resistors in the convergence circuits? Often that is what happens when the old ICs wear out it will cause a couple resistors to burn open, and they show no outward sign of being bad. Also double check the IC pins connections for solder bridges thats another common problem, I always use a magnifying glass to double check my solder when ever I do convergence or any IC work where the pins are close. But with the streaks youre describing I would think maybe resistors.

Convergance


You most likely have some resistors that are needing to be replaced its not uncommon for Samsungs ICs to open a couple resistors when the ICs go out and installing new ICs with the old ones being open can cause more of the convergence resistors to burn. Post the model number of you set and I can let you know which resistors you likely need to replace.

Your convergence ICs are defective and quite possibly the burning smell was likely some of the convergence Resistors burning. Its actually not that exspensive of a repair. you can get a brand new Sub deflection board for your set for 232.00 at the following link and that will fix your set and you just put the new board in. The site will also provide you with free on line tech support to assist you with installing the new board. you need the P54 Sub deflection board. Its available at the following link.

The resistors often burn out on that set when the convergence ic's go. The 3.3ohm 1/2watt metal film resistors those are usually the ones that burn out when the ic's go. you have to unsolder one side and lift the leg up out of circuit to check with a ohms meter. You can not check them in circuit make sure you lift a leg up to check or you will not get a correct reading

I think the hardest to solve problems are those I installed!!
Where do we start==no lecture,but I never change a resistor
unless it has changed (in value!) Use a digital meter and check
the value of each resistor.Toshiba is a bit confusing as to values
of each resistor and location in relation to the IC's.Go over your own work first.Check micro fuses in power supply=F851,F852,
etc. Carefully resolder steel jumper wires at board edge,they feed
B+ to convergence amp circuit.Be sure to verify no shorts in pins
of IC's.(use your meter).........T
