Question about Samsung 50 in. Plasma TV

Open Question

Samsung 50' Plasma has No Picture

Samsung 50' Plasma PS50C96HDX has no picture only sound. I have tested the main power board etc...
When testing the y-sustain the fuse is not blown and the low power green LED is on and if I can get power up until here it must be the y-sus board or the screen itself? Please let me know if you think it could be anything else?
Thanks - Matt

SOURCE: Magnavox 50" plasma Won't Power on/Shut's off/Blinking red LED

sherrie

I followed the solution e-mailed to me. My 50 in. phillips magnovox plasma had no sound or picture. I removed the back panel of the tv ( 55 screws) and removed the circuit board in the center of the tv. There are about 5 or 6 wire connections that you have to unplug, but they are all different in size so it's ot a problem when reconnecting. Take the circuit board to a tv repair shop. There are 2 capacitators side by side at the bottom center that were bulgeing. 3300ua 10 volt. I had them replaced by the repair shop while I waited. They had (1 ) 25 volt and (1) 16 volt available. The voltages do not have to match each other. The higher voltage is better. I put the tv back together and HURRAY!!! it works. I have been searching for a solution since last summer, Thanks to fixya.com my problem has been solved. It only cost me $35.00 total.

I thought the tv was going to the curb, thank god I didn't toss it. I hope this solutions works for the endless number of people who have posted this same prolem. GOOD LUCK!!!

SOURCE: how hard it is to replace by yourself main board Samsung LN-T4065

You need to do some more diagnosing of the problem. If you get sound and change channels take a bright flashlight and place it again the screen. Look for an image around the edge of the flashlight.
If you see an image that means the LCD controller board (TCON) is probably good.

The problem is probably one of three causes;
1) Inverter board is bad
2) CCFT (cold cathode fluorescent light) are bad.
3) Power to the inverter board is bad. You can also check the connectors.

Samsung Plasma TV has standby power but no video


Make sure your video and sound cable is working (rca, hdmi cable etc) and your source component like dvd player or settop box is working. If cable is plug into a socket AV 3 or HDMI 3 for e. g. make sure the tv is source or input is selected the same like AV 3 etc.

It is possible for the TV to switch on or off but no picture or sound. This means the input board or tv tuner is faulty in which case you need a good tv repair technician

MY SAMSUNG PLASMA HAS NO SOUND BUT HAS PICTURE BUT MAKES THE SOUND WHEN SWITCHED ON


two simple things to do:

Does set have sound when a DVD etc is connected to a rear audio/video input? This will rule some things in or out.

In the main menu somewhere are the speakers (internal ones) switched to off or external?

Samsung PS-50C91H 50" plasma no picture


If this set has a cable box, satellite box or even a receiver hooked up to it remove power from them and the set for a while and power back to see if a reboot cures this issue.

short of that someone who is willing and knows how to check things is going to have to look inside and test things, repair if not what I have suggested consists of replacing boards which can either fix the set or not and gets expensive.

Insignia 50 inch 1080 plasma - Picture only shows about 3 inches at the top of the screen


Several possible suspects include: power board, main board--first step is test voltages coming out of power board--------remotely possible also is the display itself (panel which is screen unit) if it turns out to be that it is fatal.

No picture have sound hp t5064


I have a samsung hp-t5064 with sound and no picture. I purchased a service manual and went through the check list of solving the problem. It tells you to remove 4 plugs from the SMPS board (cn810, cn809, cn808, cn807) and you should get dc voltages at test pin (Vs 207VDC) and test pin (Va 63VDC). If you do not get these voltages at these two pins you should replace the SMPS borad. My question is when all plugs are unpluged I get Vs 0VDC and Va 63VDC but when I start plugging in the plugs one by one nothing changes as far as voltages until I plug in the CN807 Main board and the voltages are at normal Vs207VDC and Va 63VDC. I am asuming the SMPS board is bad. Would I be correct?

Have sound but no picture on Samsung plasma


It's a pretty common problem. The no picture but sound problem is usually the y sustain board. I've replaced 2 on mine now. The 680uf 35V capacitors usually are bulging because one of the power transistors went and took them out. This has happened to both of the y boards I had. One time the failing y board took out the buffer boards too, and once it did not. The fix is super simple and anyone with even the most rudimentary knowledge of computers or electronics can do the labor yourself. You should do the simple stuff first by just doing a quick test with a multimeter. Just check the power coming to the y board. After that you can just remove the y board by removing 3 cables and like 3 screws. Plug in the new board and it's done! You can source the parts from a place like shopjimmy or discount merchant. 3 boards were like 200 bucks. 1 board is like 100 bucks. Labor took me 15min. Think about that the next time an electronics repair place charges you 1000 dollars. Of course they check everything (Yeah right) and warranty their work (I don't) but if you check the service manual it states that this is the most common repair. Look for the Canadian manual online. Hope this helps!

Picture is not coming on samsung spn4235


Remove the Power Supply cable to Y Main board and check the Vs voltage in Power Supply board.
1. Vs voltage is OK, replace the Logic board or Y Main board.
2. Vs voltage is NG, replace the Power Supply board.
