@budm
When i removed both ribbon cables,it stop buzzing, if only one is removed, there is still buzzing.
I've tested the fuse and i got 12v and some output test points and i got some voltages,on some points not...
Can you mark the test points on the new pictures which i should test?...Leave a comment:

Do you think that changing the TCON board will solve my problem? Is there something else that could cause the problem?Leave a comment:

Re: TOSHIBA LCD 37ZV635DG No picture but sound and backlight
Thank you both for the tips,you both helped me. First,double checked the model number,back cover says 37ZV635D and the stick by the motherboard says 37ZV635DG.
False alarm for the voltages... I have a multimeter with automatic range but i set it manual to lower value.
Now the voltages are ok, i have 12v,24v, 18v sound,5v standby and 3v power tv.
And a little progress with the picture, when i reseted the connections with the motherboard nothing happened. BUT when i removed left ribbon cable i have...Leave a comment:

TOSHIBA LCD 37ZV635DG No picture but sound and backlight
Hi guys,
need some help, on my TOSHIBA LCD 37ZV635DG i have no picture but i have sound and backlight works. After some testing,visual there are no signs of burns on any board BUT the measurements on the power supply board are almost all OL except standby (5v) and power tv (3v). You can see everything on the pictures.
I did also a flashlight test but i could not see any moving picture on the screen.
I also hear some little buzzing from a TCON board.
Thanks in advance... -
Re: Philips 42PFP5332/10 Screen Flickering Problem how to repair?
Ok,now it seems to have now a problem with Xmain board(or with both X und Y) because when i remove it, the TV turns on normaly and stays on. And i touch Xmain board when i made a short so i think i made a problem on it. All voltages are ok i think the psu board is untouched.
As i saw on youtube link u gave me, diode needs to be desoldered before checking because sometimes gives wrong voltage or in both directions when in curcuit. True or false?
Any suggestions?Last edited by nex91; 03-06-2017, 02:22 PM.Leave a comment:

Re: Philips 42PFP5332/10 Screen Flickering Problem how to repair?
So, i checked voltages and it seems all to be ok. But........While TV was powered on i was trying to check some fets and i made a short somewhere and i messed something up. Now the TV turns on for a second and automaticaly turns off again...
I am little confused so please explain me how i do the checks.
Should i desolder the components and check them or
Check them direct on the board in curcuit or
Check them with connected board to a power supply but on stand by or
Check them with...Last edited by nex91; 03-06-2017, 07:35 AM.Leave a comment:

Unfortunately not yet. I needed to order the parts from Hong Kong and i takes one month for me to get the package. But i will post the update as soon as the package come.
As they advised me to measure voltage and fets for shorts, you should also do that if u have the same problem.Leave a comment:

Re: Philips 42PFP5332/10 Screen Flickering Problem how to repair?
As i thought, allways complicated by me. I visited the best store in Vienna or in Austria for eletronic components and they have NONE of those fets...
Any suggestion where can i buy them?Leave a comment:

Re: Philips 42PFP5332/10 Screen Flickering Problem how to repair?
Thanks a lot for your help. I will change those fets and give you a feedback if it works. I have also tested the buffer with some youtube tutorial and it seems to be ok. I also changed some bad caps od the psu as shown on the pictures above, but i will change another too just for reliability as you said.Leave a comment:

Re: Philips 42PFP5332/10 Screen Flickering Problem how to repair?
Ok guys i measured all fets on the ymain board and found 3 of them on the biggest heatsink shorted (black prope on middel pin and red on outer pins and i hear a BIIIIIPPP). The board is disconnected from the tv and i measured them without disoldering. Is that ok?
I also had one with 7 pins instead of 3 and i measured it so: black prope on the 4th pin and red on every other. Correct?...Last edited by nex91; 01-21-2017, 06:14 PM.Leave a comment:
