I have a samsung lcd tv model LNS-4095DX/XAA. I am getting snowy particles throughout the image. The picture looks great except for the pixel looking particles throughout the screen. I have already replaced the power supply due to some bad capacitors. It was alot worse before the new part. Do you think it is the T-Con or main board that needs replacing? I checked all the connections and tried different cables to see if it got better, it did not.

I have a samsung ln-t4053h that had a bad caps. I replaced the caps and the tv turned on fine and i put a flashlight to the screen and the screen turns on but the backlight is on 10 and it looks like its not on at all so that leads me to believe the backlight inverter.

Hello. I have a LG 47lg50-ua that when turned on, the right half of the screen goes white. The left half still plays fine. The warrenty had just expired so. I took the back of the tv off and looked around. I noticed that the top left ribbon cable (looking at the TV from the back) attached to the T-Con board (a CMO 35-D020223) had puffed up a bit. I took the bad ribbon cable out and put the good ribbon cable on the bad side. After the TV was turned on, the right side of the TV stayed white and wo

Vizio VT470M no picture, no sound, no backlight. Power supply board looks good all voltages appear correct (24V, 5V, and 3.7V) and no "bulged" capacitors . When I unplug unit for two hours, the screen comes on normally backlight comes back up and picture is normal, but changing the channel causes it to go dead again. Bringing up menu with remote is really sluggish and when attempting factory reset, it goes black. Vizio light on the front of the TV comes on and off when pressing power button,

I have a 32" flat screen tv that will stay on for somewhere around maybe 15 minutes. It shuts itself off. It won't turn back on for anywhere between 30min to 1hr. Unplugging it and replugging it in doesn't seem to make a difference. There are no flashing code lights when it shuts off. I have opened the back and all of the capacitors look good, none blown, bulged, etc. There is no burn marks on any of the boards. I can't see anything wrong with it... Of course I don't have

I have a vizio vp50 hdtv20a. A while back we turned it on no picture and it started to smoke. After reading a little about it I decided to take off back panel and see if I could locate burnt part. Could not locate burnt part so repair man came and we plugged in set with back off and turned set on. Resisters on y main board started to get red and start to smoke. So we figured it was a bad y main board. Repair man said he would order part and get back with us in couple days. Three weeks later

I have a Sharp LC-19DV12U with a defective D501 labeled 10E241. It is located on the power supply pcb connected across the 120v input to the board. The board does appear to use conventional identifiers (c=capacitor, r=resistor, t=transformer) so I would expect it to be a diode although in fact it looks like a ceramic disc capacitor. Unfortunately, I don't have a tech manual or a parts list. Can anyone help with a part number?

I am having problems with my Phillips HTS3410d home theater system, for looking around the internet I am fairly positive the problem is with an electrolytic capacitor.

I have a LT37HVS Olevia flat-screen that has a similar problem to one of the posts. I had the same blue standby type light on the front that stays lit, but turning it on just makes this light blink, and no display.

When switched on, the power light flashes on and off on the front of the TV but no picture. We have the back part of the panel off and there are no puffed capacitors. Everything looks good except some goop around some of the capacitors. Is it normal to have goop that looks like its flowing out of the caps? Is it a glue that helps it seat better? I have access to a multi-meter and have the checked the output of some of the connectors. Anything to suggest?
