Check all the voltages before and after the tv shuts down. If they don't change then the power supply board is ok. Look to the main board because that's what actually turns the tv off

SOURCE: Shuts off

From the information you have provided failed capacitors in the power supply is likely causing the problem. The safety circuitry shuts the TV set down when it detects a problem. This model of TV has over 2,000 parts which include millions of transistors inside the integrated circuits. The capacitors will change value, leak and become defective. Resistors will change value and burn. Integrated circuits and transistors can go bad. This can cause other components to become defective, which can have a domino effect and cause other parts to fail. Replacing one defective part may make the TV operate for a short time but the part will fail again since if the parts that caused the failure to begin with are not replaced. The only way to know for sure what is causing the problem, which parts that are no longer within factory specs and for proper repair all the electronics must be diagnosed by someone with the correct electronic test equipment and the skills to use the test equipment. The repair should cost about $250 if carried into a TV repair shop. A small TV repair shop will often charge less than a large repair facility.

Problem With the Sharp TV LC-32SB23U 32in LCD TV Serial No# 810825838


Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.

Sharp aquos lc-37gv5u sound shuts off after ten min. of starting


Good day!!!


That problem is usually cause of faulty capacitors on the power supply board..

Just follow this instruction to fix your TV..

1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter

Green lightflashing on my sharp lc-32sb23u how do i fix it....


You might have a bad CCFL lamp, part #RLMPLA029WJN1, inside the LCD panel or maybe a bad power supply inverter board, part # RUNTKA448WJQZ. Both are easy to check and replace yourself. You will have to take the tv apart to replace these. Check for bad CCFL lamp first cause they cost about $19.49 ea. If you take this tv to a Sharp TV Service repair center they will tell you the LCD panel is bad and they will want to charge you $800.00 for it.
