Samsung un55h6203afxza us01 tv. Sound,but no picture. p/s burned spot near connector which goes to backlights. Replaced all 4 boards-nothing has changed. I used a voltmeter set

To vdc to test the voltage at each M+ pin of the connector for the cable which goes to the backlights. Tested with the connector plugged in and also with the connector unplugged. In both cases I found 300 vdc+- on pin #1 and zero on all the other pins. I verified the volt meter is working properly, so that's not the issue. The flashlight test shows there is a picture, but no backlights working. Appreciate any advice as to what might be the problem?

I think you missed one cap. Look for another 1ufd cap close to the jungle chip. It will have the circuit designation in the 300's like the others in the vertical circuit. It is just not located close by. I think that one will fix it.I don't have the service data with me so I can't give you the exact designation.

SOURCE: I have replaced the power supply on my Acer Aspire

When you have this problem on this PC, do not replace the power supply or the motherboard until you have first tried pulling out the video card. When the video card fails it can cause the x1700 to not power up. Pull the video card and see if it will power up without it.

SOURCE: I have a Westinghouse LCD television with built-in

I am a TV repairman and I have repaired TV's almost everyday for the last 30 years. And I know from experience that if an electrolytic is warm on the top of them that they are starting to go bad. My suggestion is this: Take the one's that are warm out and if you have a capacitor checker, check them to see if they are weak in capacitance. If you don't have a checker the best way is to replace them. It will be worth the effort to find out. I very often, take capacitors out of a spare board (not the same) and use them. I am assuming you are referring to the power supply as the main board. The capacitors that are in line with the voltage to the inverter is 24 volts and they sustain the voltage and keep it up under a load to light up the backlight. You could look and see that some boards put the voltage by the pins on the connectors and this may help if it does in this case. However, the inverter has switching circuits to produce the high voltage to the transformers on the inverter to light up the backlight and if they don't turn on then no backlight. Inverters are highly intergrated so replacement is best. Also there are fuses on the inverter labeled F1, F2 etc. Check them for continunity. It the fuses are open then you for sure have a bad inverter board.

Hi Peter,

My samsung TV UN55H6203AFXZA (Version US01) has no sound, Just wondering what part I would need to replace as I just replaced all of the boards last night and still no sound


I wonder if that TV has headphone or audio out jack? Sometimes when that jack fails it is getting shorted and TV automatically turns off internal speakers to send sound to headphones

I have a Samsung LN37B650T1FXZA. The screen has gone white with a very faded picture.


If you had a white picture the backlight converter board did not need to be replaced. The T-Con board controls the picture. This board has one or two flat ribbon cables going to the bottom of the screen. It usually is located near the center of the TV chassis.

I have a Samsung TV model UN50H6350AFXZA which has sound but no picture. Backlights work. Replaced t-con board with new one, but not fixed. What next?


Main board. T con board is only involved with video issues. Main board goes both ways and since you already replaced the T con board that is your only alternative. U got backlite so inverter board is good.

Tries tv unplung,replug it back like about an hour later.For the tv to do a resetting itself back to the factory setting.Tv now 50/50 the tv might work as normal again.If the tv dosen't.Tv have a dead 1 or 2 backlight buffers boards have to be replacing.These 2 long backlight buffers boards only job are to provided a tv plasma screen panel for a backlight to see the picture.Tv now the plasma screen panel have no backlight that why ur tv have only audio sound and no picture.No experience in tv repair and never done any electronic board parts replacement before.Best just call many tv shops and explain the tv situation it in and get the best quote prices for parts and labors.Best prices parts and labors should be around $400 is fair more than that as i said shops around for more tv repair shops.
