Re: Philips 52PFL5704D/F7 Sound and Backlight, No Video.

Just in case anyone finds themselves here needing to fix this tv by repairing or replacing the T-Con board, I wanted to leave the info that the original RUNTK 4107TP ZA Board can be replaced with the much easier to find and much cheaper Sharp RUNTK 4323TP ZZ. I have confirmed that this $40 dollar board is a compatible direct replacement. Connections are identical. I have also found out that the ZZ on the end of the number is important on this series of boards. They make this with other Z something endings on the number. Any other than ZZ may not work.

I know this is an old thread, but I'm trying to repair this same T-Con board. I was wondering if anyone knew if there would be a problem replacing the electrolytic capacitors with MLCC?

IC200 could be a THine THV3056

Clean the back side of the T-CON where the white thermal pad is and replace the thermal pad with a new one or a similar one scavenged from other TVs.

The only thing I could be missing is the IC in this kit:

I'm not able to identify it...

Anyone?

Re: Philips 52PFL5704D/F7 Sound and Backlight, No Video.

From the kit posted, they changed the cap rating to higher voltage. Therefore, I wanted to go ahead and replace them in addition to the fuse.

I looked at the OEM capacitor and they seemed to be Panasonic SVPD (page 45). So I checked their footprint and ordered something similar:

22uF, 25V x9
33uF, 25V x2

I also ordered the voltage regulator.

I'll keep you posted with the results.

So I took the chance that the tcon would repair this tv that I picked up for free. i got the tcon and installed it but now I have an issue with the screen where the left side of the screen does not display properly. I am wondering if it is a bad connection to the cable or do you think the panel is gone? I have played around with the cable connection to the tcon but it doesn't seem to do much.

Any ideas?

Got the same thing! I ordered a T-CON board on Ebay and replaced it but now I have no screen at all! Tried to put back the old T-CON board, still the same, no image. Also, sometime, the TV click, backlight up then goes off two time. Some other time, it goes on then off then on again and stays on. Can anyone help?

Re: Philips 52PFL5704D/F7 Sound and Backlight, No Video.

with the tv on, I have 11.9v on pin63. I also get 11.9v on pins 62 and 64.

Check pin 63 on ic200 for voltage.

I took off ic201 and the pads are not shorted.

I'm wondering if anyone has any input as there is a ic on the backside that control the power (ic200, part number THINE THV3056). Shop jimmy is selling a repair kit that has this ic, plus ic201 and the fuse.

Could this be the solution?

Re: Philips 52PFL5704D/F7 Sound and Backlight, No Video.

You will have to run the traces back from ic201 with meter in diode beep mode till you find problem

Re: Philips 52PFL5704D/F7 Sound and Backlight, No Video.

Does it anyone have any updates on how to repair the no voltage in the ic201? I have 12v on both sides of the fuse as well as voltages on the 2 caps closest to the fuse, BUT no voltage in all the rest of the caps.

Any suggestions as to where I can check?

That is one expensive T-CON:

Do you also get the 12VDC on the positive legs of those two electrolytic caps next to the fuse? Or on other electrolytics caps on that board.
What is the P/N of that IC201?

This is a complete list of components that are included in a repair kit sold by someone on eBay. For people that can source the components, they could probably beat the $30+$10shipping (usd) cost. Just thought I'd help other people that have been having trouble getting this expensive t-con board.

For the Philips 52PFL5704D/F7 Repair kit
T-con board RUNTK4107TPZA CPWBX4107TPZA CPWBX4107TP RUNTK4107TP

Please refer to the pictures.

That inductor and the other 3 smaller inductors (with 10 nad 22 on top) are for the switching power supplies.
There is IC under that grey square next to those two caps is probably the SMPS IC. You need to see if you can get the P/N to look up the specsheet for it.

Re: Philips 52PFL5704D/F7 Sound and Backlight, No Video.

has anyone figured out how the voltages get from the fuse to the regulator ic201
if I have 12v on both sides of the fuse - but 0volts on all pins of ic201 -I lifted the pins and still no voltages, does anyone have the schematics for this t-con?
after the fuse on the way to ic201 there has to be a diode, ic, or transistor.

The capacitors have 12v and also the coil marked in red - no where else

Any good clear pictures of YOUR T-CON board?
