Hi, so I was told to replace my psu by a tech because of what the service manual said. I replaced it and its doing the samething. No picture but sound. All of the readings are coming out correct. I tried to do a reset on the logic but but nothing happens. I can do a reset on the main input board but nothing happens after it resets the TV. The fan on the main input board does not come on at all. Please help. I can control channel, source and volume but still no picture.


This no picture but sound issue is not caused due to power supply. The loic control board is also ruled out because all the other functions are operational. That leaves us with two possibilities 1) Sustain board(S) or 2)Buffer BoardsIt is not p ... Samsung HP-R5052 50 in. Plasma HDTV

I have a LG37LF65 LCD TV. Several month ago it broke down, at that time power supply was repaired. After a while after switching it on picture started to shake and then totally disintegrated. I have taken it back to service they said this is main board failure but since I cannot find proper board. Is It sure that is main board fault or can it be anyithing else? Can I check anything to be sure?


Check the power supply voltages to make sure you don't have another capacitor going out (the first one replaced is probably OK). Poor filtering on a supply voltage could cause the main board to misbehave. If the voltages are good, the shop tech is ve ... Flat Panel Televisions

Samsung PS-42Q96HD Hi My Samsung PS-42Q96HD went dead one day no pic and no sound- so I opened up the back and on the psu I replaced 2 bulging capacitors. Now the tv comes on with sound but with no picture. As far as I can tell there is power going through the X and Y boards and the logic board has 2 green led lights on. Any ideas would be greatly appreciated. Thanks in advance

I have a Samsung PS50Q97HD plasma TV that keeps blowing new boards and I don't know why. It came to me with a faulty YSUS that had damaged the VS supply section in the PSU board. I fixed the PSU and fuse and have good VS voltage now. I replaced the YSUS main. I powerd the TV and the upper YDRIVE (Yscan buffer) board chips when pop. I put this down to it getting damaged unseen when the YSUS went faulty. I replaced the YDRIVE upper with new and then the lower board went faulty too (holes blew in t

I have a vizio vz37l tv. When i turn it on the screen lights up, however there is no picture on the screen. the sound works, its just no picture on the screen. I read on a couple of the posts on here, and figured the proper course would be to replace the t-con board. I just finished replacing the tcon board and still the same thing. I called vizio about the problem and they say that if the screen lights up then the problem wouldn't be the backlight inverter boards, that it might be as simpl

Hi, I have searched all over internet and I think you are the only one who may exactly know whats the problem. I have a Toshiba Regza 37" which has no picture but sounds works perfect. The thing is if you really focus the picture is there but its too dull and dark to see it properly. Ive heard something about switching T-Con board.. please let me know which one of the boards is that(any sign or specific connection?) and where can I buy one? Thank you very much and best regards kamran


If you can see an image and it's OK - no distortions or corruption - then it's not an image problem, it's a backlighting problem. This means that the faulty part is not the T-con or any other board that works on the image, it's the inverter - the bo ... Flat Panel Televisions
