Make sure all your cables connected are connected correctly first.then try it with another t.v if you can because it could be the T.v that is faulty and needs to be fixed or replaced.

HI, I have a 40" Samsung Flat Screen TV (Model:


This will not be easy to be 100% correct as to what part is bad as you can see in my pictures here.
It can be bad main board, T-CON board, Bad LCD panel.

I would try new T-CON since it is the cheapest part, not worth to repalce LCD panel.

I have not repaired this particular model. But I have repaired another polaroid flat screen TV. I can tell you for sure, the biggest problem here are bad capacitors in the signal board. You may find 15 or 20 bad caps. On the power supply there may be a two or three caps that need replaced as they will be weak but not real bad. Yes,the majority of the caps will be found in the signal board. You will need a good capacitor checker to locate these. It will require patience and skill to remove and replace these caps. I cannot say enough of bad capacitors in this TV. Find a TV tech to help you! Thanks for asking, show me a few hands of appreciation. This answer is your best effort for repair!

Ultra LCD 30-500 TV, audio but no video. Worked fine for 4 years until 3 days ago when the screen would go black intermittently. Now there is no video period, only audio. Does anyone have a solution or...


The problem can be bad backlight inverter board or the 24vdc power supply for the backlight inverter is not working, it is easier to look at the power supply module than to get to the inverter board, These are the two most failure parts in LCD TV. Look for bad capacitors in the power supply first or burnt parts.

Ultra 40" LCD40-500--- Need power supply for this LCD TV--- see below for spec's

Hi!

If anyone would like a Power adapter for their Ultra LCD30-500 and LCD40-500 - please email me Acosta.cal@gmail.com... And I’ll be able to order one…



I too own a Ultra Lcd40-500 HDTV. Bought it from HSN.com back in 2006.

My power adapter burned out 2 weeks ago, and to my dismay PWW, or should I say POS has gone bankrupt.

I looked everywhere online and here in San Jose,CA thinking I would find a replacement or at least someone that could repair the blown capacitor( 630v vpmm), thermitors(IRFD460A) and varistor( SCK206).

After calling every power supply company, distributor, and retailer, had no luck finding a match to this crazy looking 9din pin adapter. Disappointed I gave up on a replacement and took it to various repair shops for repair and was told without schematic would be nearly impossible to replicate the power Output. Finally this one shop was able to replace the burned out components and it seem to work at the store. When I got home with it..no luck..red light would come on…but no light on screen. L

Not wanting to give up or trash my LCD. It was time to dig further…I did some research through my employer; a SemiConductor company here in Santa Clara, CA.

Needless to say this power adapter has driven me crazy….It has been exhausting... But finally just yesterday I got the break needed…I found a manufacturer in Taiwan that has these power supplies for both the Ultra lcd 30" and 40". I was told they only sell to Component or Electronic Suppliers. I’ve asked my employer to see if I would be able to order one on their behalf using their account.

Happy ending! My power supply is on it’s way. I was told it could take up to 4weeks for delivery. But I’m just glad to have a replacement.

Colored vertical lines with sound no picture


im afraid to say that your display has gone the best thing you can do is call the supplyer of the tv if its under warranty or call samsung. the cost of a new display will be 400 - 500 pounds so you may have to buy a new set.
