Repost last comment on pt-47wx53g problem


Hi, I post here my last comment, follow the diagram at page 44, leave the checkup at page 16, for some of the test you need raster, and the TV is in protection mode now.
From protection mode follow troubleshooting diagrams, I think is page 44/45.
There are many faulty component that can give you blank screen with no raster, the strange things is that the TV stays on, has sound and is not on protect.

Test also the sygnal boards (the ones with the AV connectors) and see if it makes any difference switching the signal to a different input, this TV has several ICs that manage the video signal, testing blindly will give no help. Follow the diagrams on manual.


I think the following was my last comment:
-----------------------------------------------------------------

You need to follow the troubleshooting charts at page 44 of user manual.
(download the service manual here)

Regarding the jungle chip, that is just a familiar name for the main computer CPU, service manuals rarely call it Jungle chip. Your jungle Chip is the main processor, IC4511, be careful handling the component arount the IC4511, some IC in there is sensible to static charges in your hands, better to keep fingers away.

In your case I would start testing following the diagram at page 44 of SM. I will also test the pico fuses at the base of convergence ICs, if the STKs had been replaced
That is what you do when the nature of the problem is not clear.

Since there is no protection mode on, the fault
can concern IC3001 and IC3002 that are vidio processors, and other parts involved.
If at any point you get the led on, and TV going in protect mode, with a flashing led, that is a step forward, means that the jungle IC (The IC4511) had detected the fault.

Start testing following the procedure at page 44, or same page on your version of service manual.

IC4511 is on DG board. Asterisk indicates whole board is to be replaced. In schematic, labeling on IC4511 indicates it does some form of video processing. Manual instructs to add an "S" at end of board part number when ordering.

No start, 5 blinks of the power light, pause 5 blinks etc


Thats the code for IC4511 on the DG board, you will need to replace the entire DG board. You can get one at the following link, just leave them a email with your model number and what your error code blink is, they respond quickly.

PT-47WX54J 5-blinks between pasues - no audio or video


IC4511 is defective when the led blinks 5 times. that part is unavailable so you will need the entire circuit board.

TV screen goes blank but power stays on


There is no way to tell if it needs just resoldering only a couple minutes if the vertical IC is defective most shops will say you need a new Circuit board. thats sad to say but most shops dont do component level repairs anymore, they just switch Circuit boards as they can charge more that way, and not have to reply on having the experience to actually diagnose the problem.Thats very unfortunate but true.

Deflection Board


That part is no longer available as an entire board. It would be possible to repair the module or perhaps locate a rebuilt one. Check with a company called PTC. They rebuild modules.
