    SINCE, DAEWOO WILL NOT RELEASE THE SERVICE MANUAL TO ME I WILL NEED TO TAKE MY UNIT TO WHERE THEY CAN SERVICE IT. IT MAKES ME FEEL SAD THAT THE COMPANY WILL NET SELL ME A SERVICE MANUAL BECAUSE, I AM NOT AN AUTHERIZED WARRENTY DEALER. IF WE CAN'T OBTAIN SERVICE MANUALS FOR OURSELFS EVEN A TECHNICIAN IS NOT ABEL TO BUY ONE. I LIKE TO REPAIR MY OWN SYSTEMS, I ENJOY TROUBLESHOOT IN ELECTRONICS. I USE IT AS A HOBBY.

Since I don't know what model it is, I am going for a shot in the dark. I found a place that has service manuals for Daewoo for free. If none relate to your DVD player, please give me the model number and I may find one for you.

What are the volts outputs of power supply?


Hi Jhun,
As a general rule as soon as you switch on the TV, the power supply must produce stand by (sb) 5V or 3.5V as per the TV's design. Next, when you give power on command, the power supply should produce power on 5V or 3.5V, 12V and 24V or some other voltages as per the TV's design. All this is printed on the power supply pcb in most TV sets. I hope this helps.

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...


Im having similar problem and with my limited knowledge of lcd tvs and the voltages ALL being good except the pwr on or sw on voltage from the main board to the power supply which tells it to switch everything on Im guessing that something is going wrong on the main board. In the condition where it freezes it (the power on V) which switches everything on i get varied voltages such as 2.5 or 3 or (the normal 5v) and then when nothing powers up (blank screen) i read 0v on pwr on voltage but all my other voltages are corect (24v to inverter, 12 v to main board, 5v, etc.) Im guessing from researching this is that there is in improper voltage somewhere in the main board circuit. I have been unable to find it so i may order another board and post back.

Tv turns on shuts off and the power light blinks 10


Hi,

10 blinks on Panasonic TH-42PX75U is a fault either on the 5V, 3.3V, 9V, Tuner power. The suspected board that is gone to malfunction is either the P board (power supply) or the A board.
To isolate which board is faulty, you have to test the output voltage of the P board through connector P6 and P7 using the multimeter set in DC measurement.
You must get 15VDC (P6) pin 1,2,3.
You must get 15VDC (P7) pin 1,2,
You must get 5VDC (P7) pin 5
You must get 5VDC (P7) pin 10

If there's a missing voltages above, you have to replaced the P-board.
Note : you should placed the multimeter test prod to the said test point prior from powering on the unit to get an accurate reading.
If the voltages are intact, you have to replaced the A-board.

Here's the link for the boards or obtain it from your local Panasonic Service Center.
P board
A board

Please double check the actual part no. of your board before ordering online to ensure you will get the exact replacement.

Also, please check if your unit is under warranty period, avail it because the manufacturer will fix it for free. Opening the rear cover will void the warranty.

Hope I helped you.
Have a nice day!

Cyberhome CH-DVD 300 DVD - YELLOW light indicator of what problem?


Marlin P Jones & Assoc. Inc.. has a 5V 2.2A /12V 1.5A cord power supply that will fit into the space where the original power supply was! Lists for $6.95 but online price was $2.95. Works great! Connect 12V supply to the yellow lead and the 5V to the red lead of the output connector, black is ground, common to both supplies. Use QC terminals to the power cord input terminals, remove the cable clamp and the power supply will nestle beautifully in the space without need for support. (Remove the old circuit board plastic (3) and rear brass standoffs and use the front brass standoff for the output cable shield ground connection. (Part No. is 15955-PS) I bought two because I have a 2nd Cyberhome CD-DVD 300 which hasn't crapped out yet.

Power on but nothing else


My DVD22 did exactly the same. The solution mentioned by shelompidid not apply to me since my model already had the fix factory fitted.

The other problem mentioned on page 21 of the service manual did the trick for me, although the complaint does not seem to be directly relavant:

"Complaint: Will Not Read Disc; Other Functions May Be Disabled
See h/k service bulletins HK2004-03 and HK2005-02, as the issues covered there involve similar
symptoms.
Probable Cause: EC19 and EC20 (1000μf 16v capacitors) may be defective in the power supply. This can be checked by measuring the +3.3v and +5v voltages that are associated with EC19, 20 to see if they are low (more than 0.1v low). The SPMS output voltages are marked on the PCB adjacent to the large 13 pin header. While there is only one 3.3v pin, there are several +5v pins, and care should be taken to measure the correct one(s), which are either two +5v pins approximately in the center of the header.

I could actually see on the power supply board that these two caps were damaged, although they were not completely popped. An additional cap which was damaged on my board was EC4.

When I measured the voltages the middle D +5V was reading about 4,6V. I did not expect a problem until I read the statement above on page 21 stating it should not be low by more than 0,1V. My A+14 and A-14 voltages also read about +/-17 to +/-18V.

I replaced all three caps: EC4, EC19 and EC20 with 25V caps instead of 16V caps. The voltage for D +5V now read exactly 5,01V! The A+/-14 read +/-16V (some improvement).

My unit is operating fine after replacing these 3 caps! I suspect that the damage to the caps could have been spikes on the AC suppy some stage, maybe due to lightning. Pretty amazing that only the power supply have damage and not the main pcb.

turn the power on. to get rid of the red light you need to press the timer/rec button on the remote until it turns off. the red light means it is programed to record.

The power supply needs to be changed. Not sure how you could do that since this item is from china and I could not find parts for this unit.

Loading fault


check power cables to dvd and hd. voltages should be 12v,gnd,gnd,5V with and without load. if voltages drops with load then fault is probably with caps. I changed one cap when voltage dropped in dvd powercable(5V). cost only 0,50€ to fix powerboard. there is a high risk for electrical shock so if youre not familiar with electrical devices and dont know how to perform these checking operations and so on... then PLEASE take your unit for professional

No Power


ok! make sure ur IC regulator is good. like the 7805 or 7812 or 7809 u make sure that the following ICs are correct in voltage! 7805 is for 5V. 7812 is for 12V. 7809 is for 9V MAKE SURE THAT IS EXACTLY IN VOLTAGE!
