Model UA40F5500AR. half of my LED TV screen is covered with cloud. Full picture is visible. But half screen has light black cloud.


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Keep blowing the main fuse.


To which circuit section did you replaced the fuse? Main power retulator? Just understand, the fuses are used to protect the circuit and TV from any short circuit or over voltage. Without any one of these, no fuse will blow up. If it was due to over voltage, the set should work after a fuse replacement. But here, the fuse blow up again, means, there is some thing shorted component/s. Check which component is shorted, and replace it, before replacing an other fuse. One more thing to say is, never insert a fuse other than specified. The voltage and ampere specification to fuse, will be marked at the circuit board, very near to the fuse clamp. Insert a fuse of same rating only. Using other fuse, rated higher ampere rating, might make things worse.

Hi,
Most probably, Electrolytic condenser in the Power supply to display circuit may have punctured resulting in smoke coming out. Take tv to service centre. There is no other option.
Good luck.
Rating the solution is highly appreciated.

I was watching TV and it just cut off. There is no power light on and the outlets are working and the cord is firmly in.


good day sir/maam, chances are yout tv just blew a fuse, when a fuse blew up, there are several reasons.
  • It protects your tv from further damage.
  • a part of your tv got bad, causing it to blew.
You have a choice of calling your service center/dealer or do it your own.

If you decide to do it yourself, these are the steps you may need to do.
  1. Open the TV's back cover, to access the circuit. locate the blowned fuse.
  2. you may need to pull out the entire board, to test it.
  3. test the switching regulator IC/transistor for shorts, (you may need a multitester).
  4. check for open low value resistors, less than 100 ohms.
  5. You really need to find the cause of the blew up fuse. part by part checking is necessary,
  6. replace the bad parts and test again.
  7. if everthing else fails, you really need to call your service.
note: if you simply replace the fuse without tracing the blew up shorted bad part, chances are the fuse may blew again.

Working fine, then loud squeal and some smoke, picture was still


The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
Search the site by type in the "brand name" to your device; in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

A chip on the circuit board started smoking


The component sounds like a resistor, and the fact that it was attached to a heat sink means its a power handling resistor. You said it was burning, so this means that whatever it is attached to is drawing too much current. From what you are saying a component on a board is drawing too much current and is causing another component (the 1 ohm resistor) to burn. My question is what board is this (I am suspecting the deflection or the HV power supply). Please post a picture of the board in question. That way I have a visual guide as to the board and if I can find the schematic, or if you can supply the schematic I'll be able to at least give a better diagnosis of this problem.

Thank you,

Fuse location on tv


a fuse is a small glass tube about 3/4" to 1". it is located near the end of the power cord inside the tv. it is located in the power board supply circuit. there are several reason why fuse blew up. 1. sudden surge current/voltage in your area 2. shorted in either power supply or horizontal deflection circuits. when replacing fuse, be sure to change it with the same value. but if after replacement has been done and the fuse blew again, there is a short in the circuit as stated in reason no. 2. refer to a qualified service technician if you are not inclined with this job. good luck!
