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

1 Answer

I attempted a repair

I believe I fixed the solder pads and the tracers that were damaged, I tested the set and still have the three blinks for the convergence board. I've read up a little on using my multimeter and was wondering if you could reccomend any resources that would give me enough detail so that I can begin to check the components that lead into the chip, I have the manual, schematics, a multimeter and most importantly time. Im currently not confident on how to test them safely with out creating a cascade of new problems. Also there are four 2.2Ohm (i think) resistors in circuit to the IC that have a slight browning around the center (not the indicators bands), other resistor with the same markings do not, I don't believe the brown to be excess flux, is this an indicator that the resistor is shot? Again any feed back is useful, I know this is a large task to take on for a novice so any basic info or refrence material would be appreciated. Thanks again, matt
P.S. - this TV is quickly becoming my white whale.

Yes those resistors are open. If you remove 1 leg of each of those resistors out of circuit then test them you will find that they are open, replacing those with the same rated flameproof resistors should solve your problem. You can contact me at slinteriors@yahoo.com and I will send you some Ebooks that will give you some basic instruction on electronic repair. I have a wealth of information and I dont mind sending you whatever can help you learn electronics. Its a fascinating field.

I have a WS 65908........it has the same problum--listed on this site.......power on for 3 seconds...and it said this.... Do the self test this model has: When set shuts off and on front of set power...


Error code 23 on this set means that the Horizontal Deflection circuit of the set has failed. Usually this points to a damaged Horizontal Deflection IC and sometimes the HOT(Horiziontal Output Transistor) as well, not to mention the resistors that are blown when the IC failed. Replacing these parts should resolve the problem.
PS:Note that the Deflection circuit involves certain high-voltage components and prior to repair it is advisable to discharge the high voltage before attempting the repair. You will also need to know how to use a multimeter(to test the HOT and look for blown resistors) and a soldering gun. If you think you can do it yourself, let me know and I will provide you detailed step by step instructions.

Sai.

My car came with two sets of keys they have a door unlock/lock button, trunk button, and one for the alarm. They both stopped working so I bought new batteries. I had put them in and it still never worked....


Re: Key Fob - U shaped battery hold down bracket. (Open key fob with a small pen knife)

This battery holding bracket commonly becomes dislodged from the circuit board when you drop the key fob due to the weight and momentum of the battery. Closely examine the bracket and notice there are three little projections that align with holes in the circuit board. The only thing keeping this bracket in place are three points on the opposite side of the circuit board where it is soldered. It is easily repaired if you have soldering skills. Obtain a 27-watt soldering iron from Radio Shack and rosin core solder. If the bracket is still partially attached to the board, heat the solder pad(s) and completely remove the bracket. Next, heat each pad and open the pad hole with a pin or tooth pick. Clean any excess solder off the bracket's mounting feet and re-solder making sure it is flat against the board. If any of the mounting tabs are broken away, remove the broken piece from the pad hole. Then solder a short piece of wire to the side of the bracket as a substitute, insert & solder to the board. Install a fresh battery and test. Caution: Do not apply excessive heat to the circuit board. Do not use high wattage soldering gun.

The tv just went blank whiles i was watching. An oracle light writted "off timer power" is indicating. I don't know what is the problem


The most common problem with this set is the convergence chips fail.To repair this type problem you need test equipment and soldering/desoldering tools and supplies. Most repair shops can repair this problem for 150-295 us dollars. If you attempt to disassemble the tv by yourself you risk damage to a light sensor that will render the set inoperable.In other instances I have seen bad solder connections and transistor failure on the boards but all these are repairable problems. No circuit board replacement should be needed. Good luck Russmann.

Dear SD Tech, My WS-65711 suddenly stopped turning on. It will click the relay and turn on the front panel light for a couple of seconds and then turn off. I did the self diagnostics and got 2 blinks,...


Hi,

It seems that SD tech is not available at this moment unless he might have answered this question. I would be glad to help you to fix this problem.

the code 2-2 does indicates a short protect fault, which is usually caused by a failure in the convergence section. This is a very common repair in these sets. The typical repair involves replacing the convergence ICs (integrated circuits), and testing/replacing two small pico fuses.

The replacement ICs for your set are part number: STKxxx-xxx and are available from www.encompassparts.com for $19.95 each (needs two). You will also need at least one (likely two) 5 Amp pico fuses. If you wish to repair this yourself, the ICs are located on the large heat sink on the center (Power) PC board. The fuses are also on this board, near the center, location numbers: F9A04 and F9A05. You would need soldering equipment and very good soldering skills to replace these parts.

If you were to call a local shop to repair this, the labor to replace these is roughly $250-275 (in my area) if the TV were brought in to the shop. Please add a trip charge if repaired in the home.

The fuses must be tested with a multimeter to see if they are bad. They are only $2.50 each, so most people without a meter just change them both. If the repair has any problems, like a solder bridge, you may need a meter to check them after that. A good magnifying glass helps prevent solder bridges (for me, anyway).

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

The USB port on the remote has fallen into the body of the remote. We removed the screws but still can't get it open??


The Ebay service is quite reasonable, but I give you fair warning. Many times when a USB port has become loose, it has done so due to some violent action. If this is the case, then it may not be a simple fix of re-soldering the port. If the solder pads have been ripped off the logic board, then this becomes a much bigger job and the Ebay service will not attempt a repair on the board itself. So, before you set yourself up for dissapointment, you should try to take a look inside to see if there is damage to the board. To open the remote remove the two screws. Then, near the bottom of the remote, on either side, stick your thumbnail between the two clamshell halves of the remote and wiggle it in until you open up a little space. Then, pointing your thumb down at about 45 degrees, slide your hand up the side of the remote. This will pop the small tabs that hold the remote together. Do the same on the other side and you will be able to separate the top and bottom clamshell halfs. Then, just pull out the red LED protective lens in the front. You should be able to recover the USB port and inspect the 5 small solder pads (thin silver-colored "fingers" on the logic board that the pins of the port were soldered to). If they all appear intact, you can attempt to repair yourself or contact the Ebay repairer as suggested. If any of the solder pads are missing, then the damage to the board is much more serious and, although it can be repaired, no one is going to do it for small change. You would probably be better off just buying a new logic board from an Ebay re-seller. They cost about $27.

The connector of my flashdrive is broken or bent.is it possible to fix it ? and how?


I have fixed many broken connectors, sometimes they are simple, other times they are tricky ( a broken connector can sometimes take part of the Printed Circuit Board with it ) and require very delicate skill. If the problem looks obvious you could attempt a repair. If the data is important and you need it, send it to a professional data recovery service. Believe it or not solder in the wrong places can seriously damage the chances of a successful recovery. I now run a simple mail in recovery service http://happydatarecovery.com/ , mail your drive in and get the data back.

I have two magella 4040's I was using themin a semi with them stuck to the windshield the solder joint on the charging port is weak, The 1st one had a 180 degree jack , straight out, the second one...


Re soldering the port is ok if the port it self is not damaged..they have A centering pin on the bottom and once they come loose for what ever reason, They shear that pin off, then theres Not much to keep them from moving again Because that pin on the originals Always break off. I also use a little hot glue To keep help keep it put Just As a precaution. The ones I sell, I haven't had any returned yet neither the ones I fixed or The ones the people put the port on themselves, I have however had to guys wanting me to fix there 4040 because they ripped the tracers off the board. (now there junk) I cant repair anything that has the tracers damaged, If I get one like that, I do not even try to fix it, because its beyond My capabilities. To answer your question I do sell the ports for 14.99 on ebay 12.99 off ebay shipping included And yes I do repair them but not if the tracers are damaged. I normally charge 45.00 to repair them and I pay the ship back but if you want me to do both of them And your going to pay shipping both ways. Ill do both for 80.00 I'm not trying to talk you out of anything but if you can solder half decent, I'm sure these would hold up for you, the hardest part is removing the old port without damaging the tracers

SONY WEGA KV-36HS420 will not come on


The blinking is an indication that the set detected a problem. The code usually indicates a bad regulator circuit. If yu can solder, you can probably fix this your self. Please let me know if you wish to attempt the repair. If not, expect a parts cost in the $25-$40 range plus the local labor rate for the repair.

I attempted a repair on my pt-53tw53 by replacing the 110 ic chip ( the one on the diagonal heat sink) but, I think I did a bad job of soldering. When I tested the set when turning the power on the set...


You can repair any of the traces with small wires from the affected pin to the next componnent on that trace. To remove the board label all wires that you disconnect. There are "bridge" connectors that connect the signal bd and main bd. these lift up off the main board and will stay attached to the board youre working on. If you need further info please let me know. Also use solder wick to remove the solder and get a small tip solder iron 30watt from radio shack. The proper way to solder is (1) allow the iron to heat up. (2) touch the hot tip to the pin on one side and then briefly touch the solder to the other side of that pin so the solder flows around the pin. Use the solder sparingly so you dont bridge the pins with solder. (3) always check your work with a magnifying glass to insure the pins arent bridged.

Sony 32XBR400 Wont Power On


I do not believe the set is too far gone. The standby light blinks codes up to 7. If the standby light blinks more than 7 times it usually means that there is a short on the clock or data line. There are several small zener diodes connected to the clock and data lines in a couple of different places on the main board. Many times I have seen one of the zener diodes become very leaky, usually along the back of the board, loading down the clock or data line which produces the symptoms you are seeing. If you have no experience locating shorted zener diodes and unsoldering and soldering small parts, allow a qualified tech to service the set for you.

Has anyone had problems with connecting an 'HDMI to HDMI + SPDIF + RCA L / R Audio Extractor Converter (HDMI input,HDMI+ Audio output)' to a Panasonic PT-53TW53? I have a TiVo Premiere hooked up to my Panasonic PT-53TW53. I use the HDMI out, and RCA R+L outputs on the TiVo, and hook up to the digital in connections on the TV. The conversion of the HDMI out is via an HDMI to DVI cable. This has worked perfectly for years, but recently I wanted to disconnect the TiVo and replace with my Roku or Amazon Fire TV. Both have a single HDMI output. So I purchased an AGPtek HDMI to HDMI + SPDIF + RCA L / R Audio Extractor Converter (HDMI input, HDMI+ Audio output) box, hooking up the HDMI output from the Roku or Fire TV to the input on the extractor/converter, and simply disconnecting the HDMI to DVI and RCA R+L outputs from the TiVo, and plugging them into the outputs on the converter/extractor. The converter/extractor has a 3 position switch: PASS, 2CH audio, or 5.1CH (via and SPDIF or Toslink cable). I have had 2 of these converter/extractors, and with both the Roku and Fire TV I got the same results with both converter/extractors: With the switch on 2CH, which is where I understand I should get HDMI video and 2CH RCA audio, all I get is the RCA audio. No video. If I switch to PASS I get video with no audio. Of course on the 5.1 setting I get nothing, since the TV does not support SPDIF. Yet I see reviews all over Amazon indicating folks are using this converter/extractor for this very purpose, and it is working fine. I can't possibly imagine that it is some sort of incompatibility issue with the TV, since the TiVo has worked (and continues to) fine for years. Any ideas?
