[bohaboha]

hey everyone i have this Daewoo that I have found in garbage, I thought it would be easy with a few capacitors to be replaced but i found a blown resistor R14 on the power board I hope you can help me.I have taken some pictures but they were bad so I add here a copy from the internet I have done some measurements but I'm not sure if they are right for my dmm is not of the best quality but I have a "Digi Check 3 from Steiner" that did the trick when it comes to VAC and VDC I have started with power board FEL-42-C2 on which I have marked the different values of the image itself and som images of the tv i have to say that all the DCV are done with power on otherwise nothing att all.We use 220VAC in Stockholm.Any help are realy welcome thank you

No one is going to help you without good pictures of your boards. Distance troubleshooting is too difficult without them.

Re: Daewoo LCD 42" model DLP-42C1

So... Did you tell us what the problem with the TV actually is?

Does it show a power LED when plugged in?
When trying to turn it on does the LED change or disappear?
Does the backlight illuminate?
Does an image show?
Can you get sound?

Re: Daewoo LCD 42" model DLP-42C1

i forget to specify that the LED is blinking all the time from red to green

[tom66]

Re: Daewoo LCD 42" model DLP-42C1

The LED blinks green/red as soon as plugged in?

Re: Daewoo LCD 42" model DLP-42C1

yes

Re: Daewoo LCD 42" model DLP-42C1

I would immediately suspect the main / AV board...

Re: Daewoo LCD 42" model DLP-42C1

not the power board? even if it was a broken resistor on it R14

Re: Daewoo LCD 42" model DLP-42C1

No signal is going to the power board to turn it on, the power board may also be faulty but in the very least the main board appears to be too.

Re: Daewoo LCD 42" model DLP-42C1

so i have to start with the main first i did some mesure on it only when power is on

Re: Daewoo LCD 42" model DLP-42C1

Good luck, and it's great to get spares into the market. Remember to label parts correctly, or they will not be found!

Re: Daewoo LCD 42" model DLP-42C1

hi again first i want to explain that i have an usual Dmm :BST=British Standard Tester

model number BS1901W and when i test with this on ohms he is standing all the time on 1 to the left side of the screen it seems to be normal when i asked the seller here is some pics
