Power supply AD-12014(I) two smd burned

I have the same fault. I'm in Malaysia. The R57 is the blow out resistor for the "compter section of the board. Mine appears to have been caused by the Transient Voltage suppressor clamping. TRSB1 and possibly the diode (ultra fast rectifier) D5.. Did you find the resistor value?

600 ohms

A resistor with a number code instead of a letter code is a SMD:
Surface Mount Device. You might have searched for SMD resistor code and got some hits.
The system for SMD resistors is:
1st value-2nd value-multiplier
6 - 0 - 1 following zero
= 600 or 600 ohms
603 would be 60,000 Ohms or 60k
6 - 0 - 3 following zeros

Hi Giuseppe,
Better go for a new power supply board. Burnt SMDs are hard to get. Good Luck

• Transistors QX801 and QX802
  
• SMD resistors RX802, RX803, RX832, RX833 (all with the same value)
  
• SMD resistors RX804 and RX805 (same value)
  
• SMD diodes DX803 and DX804 (same kind)
  

can buy parts online or on e-bay.

Clearer picture, same board, r57 can be read upsidedown 220, or 22 ohms.

This issue here with the powerboard and the resisters on the Ysus is related to purchasing the WROUNG power supply unit. What I recommend you do is take the old supply out andmatch up the serial number and part number to get the EXACT unit.

You simply just cannot purchase a part on ebay and expect results. Many times people sale things and not know what type of output voltage the TV is supposed to take, Resulting in further damage to the unit.

Partstore.com would have this part for you. I recommend using the part number of the chasis. You will now have to replace the power board and the Ysus.




Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/edwy_1a56970cf1ea4620

Silicon Epitaxial Planar Zener Diodes for

Stabilized Power Supply

open the following link and it help you it has all the detail about the mentioned diode

is better to exchange all power unit , or you must exchange all semicondutor units as (ic, diodes, cap and several resistors), and normaly the board must be burned with heat and loose insulation)

try and trace where they are coming from and where they are going to. that might help you know a range of values

The best way is to get one off ebay by part number. Take it apart and write them down. Then order the resistors and you will have 2. Then you can either sell the other one back or keep it. You cant lose if you have electronics skills.
