Resolder cold solder joints at diodes in secondary of power supply.

There is probably a cracked or loose piece of metal somewhere for the power running from the board to the screen and speakers. It will most likely be on the board. See if you can find it, if you are choosing to fix it.

Be careful of electrical shock though

If you can't find it, a trained technician should be able to help you out.

You can also contact Daewoo about your problem and they can help you with any questions you might have and see what they would do in this case

    We don't know the board number off hand, if you contact the company, they can tell you everything you need to know and can even ship you the piece that you need, I'm sorry but I don't have the specific number, I would have to call myself and ask and since it is your tv and you will be ordering it anyway, it would be ten times better for you to call them.

    might be better if you contact a professional and take it for analysis, that should be free. Repairing might cots.



    Theres high voltage in there, and if your not trained its not smart to go in there.



    If you need more asistance, let me know. Good luck.

Power supply module located near horizontal yoke receptacles beneath a larger 5w resistor

    CRX3401 is the chassis designator for bridge rectifier in the power supply. Check your board again for correct resistor designator.

Hey i have a sony kp-51ws520,, an its standby light is blinking 9 times .. but i can play with the remote every now an then an it will come on ..nothing wrong with picture or sound. can you help me out


The G board has a diode #6301. This board is a tan color farthest to the left. I went to Radio Shack and bought a 200V 1A silicone diode and replaced it. Worked like a champ. You will need a 15W pointed tip solder iron and a steady hand. You can replace the board if you like. I found one for $70 on ebay, but the diode is $1.

No sound, no picture but timer srandby light is


If the stnadby light blinks 9x, there is a leaky diode in the G board(5Volts standby circuit) causing the problem. I don't have the service manual but I remember it's the D6301. To make it sure check all 8 diodes including the one in zero detection circuit(all in G board). Hope this helps :)

No picture or sounds red light blinks 10 times


The parts you need are two diodes, D6301, D6309, and D6116, Sony part numbers 6-500-567-21 (D6301 and 09) and 8-719-081-97 (D6116), they are located on the G board, and that's located on the left side of the set, as seen from the back.

D6116 is connected to pin 9 of transformer T6101, and D6301 and 09 are in series off of pin 7 of that transformer.

42pf7321d/37 phillips plasma tv


i am familiar with this power supply in philips models. this fault code on the psu refers to a fault within Vscan circuitry. you will be unable to check correct voltages as the set is in protection mode.

you can disconnect the Y-Sus board(to the left of the psu) and if the led stops flashing you can almost guarantee the Y-Sus pcb is faulty!
