Philips home theatre system hts35650 stoped working After switched off the power. How to fix it


Perhaps the surge strip has blown a fuse. Try plugging directly into a wall socket, bypassing the surge strip. If it lights up, then you know you have to get a new surge strip. In any event, it is most likely a fuse that's either in the surge strip itself or in the rear of your Philips receiver, near where the AC plugs into the chassis. All electrical appliances and devices have a fuse. Find it and take a look and see if you can ascertain if the nicad wire is broken inside.

Samsung LE32A4566C2D flat screen tv wont turn on?


There is a chance the power supply is fried. However, I've seen some Samsung power supplies that have fusible resistors in the power supply for added protection. So your main fuse could be ok, but there could be an additional fusible resistor in the board as well. Also be aware, depending on where the surge entered the TV, you could also have a defective main board. Not trying to rain on your parade, but surge damage can sometimes be severe.

Fuses, Switches, Circuit Breakers And Relays Most vehicles use one or more fuse panels. This one is located on the driver’s side kick panel tcca6p01.jpg

It is possible for large surges of current to pass through the electrical system of your vehicle. If this surge of current were to reach the load in the circuit, this surge could burn it out or cause severe damage to the vehicle’s electrical system. It can overload the wiring, causing the harness to get hot and melt the insulation. To protect vehicle wiring, fuses, circuit breakers and/or fusible links are typically installed into the power supply wires throughout the electrical system. These items are nothing more than a built-in weak spot in the system. When an excessive amount of current flows through a circuit it causes an increase in heat throughout the wiring. Fuses and circuit breakers are designed as the weak link in the system and will disconnect the circuit to prevent damage to the components contained within that circuit. Components are equipped with connectors so they may be replaced in situations where they were damaged due to a power surge.
The following are descriptions as to how fuses and circuit breakers protect the electrical system:
  • Fuse- A fuse is a weak link in the system designed to create an open circuit when the amperage flowing through that circuit exceeds the limits of the fuse. As the amperage increases, the conductor within the fuse heats up and eventually melts and breaks apart. This open circuit interrupts the flow of current and protects the components in the circuit.
  • Circuit Breaker- A circuit breaker is a "self-repairing" fuse. It will open the circuit in the same fashion as a fuse. The surge creates heat the same way that a fuse is affected. When the surge subsides and the circuit cools down, the circuit breaker will reset and allow current to flow through the circuit. Typically circuit breakers do not need to be replaced.
  • Fusible Link- A fusible link (fuse link or main link) is a short length of special, high temperature insulated wire that acts as a fuse. When an excessive electrical current passes through a fusible link, the thin gauge wire inside the link melts, creating an open to protect the circuit. To repair the circuit, the link must be replaced. Some newer type fusible links are housed in plug-in modules, which are simply replaced like a fuse, while older type fusible links must be cut and spliced if they melt
CAUTION
Always replace fuses, circuit breakers and fusible links with identically rated components. Under no circumstances should a protection device of higher or lower amperage rating be substituted.

I would get a fuse tester that can test fuses while still installed and powered up. It will light if the fuse is blown when applied to the two tabs that are exposed on fuses that are installed in your Ford product.

Check the fuse box under the dash on the driver's side, and check to see if there are any fuses under the hood.

If you don't have the tool, try to look for stickers or download the manual from ford.com.

Tv does not turn on after a thunderstorm and several attempts at power returning to the home. The power went on briefly then shut off several times, now the television will not turn on. We had the tv...


Check the main fuse in the power supply, the TV also has small surge protection devices (MOVs) installed after the fuse, any surges the come along and big enough will cause the main AC fuse to blow. When you surge protector, EVERY connections must go through the surge protector, for example, the AC cord of the TV is connected to the surge protector, the cable connection did not go through the surge protection, the surge then can get to the TV through the cables.

Westinghouse model tx-47f430s lcd tv wil not turn on


This is known as SLEEP MODE problem.

Simple solutions:
1. Get a power surge protector / strip.
2. Plug your TV power cord to the power surge.
3.Then turn-on your TV using the remote control. Just in case it won't go all the way to normal state.
4. Turn-off the switch of your power surge like 5 times with an interval of 3-5 seconds.
5. Then repeat step 3 and 4.
6. These step is done to over-ride the sleep mode.

Hi Geoff, You will need to open up your monitor. There will be a pcb fuse in the region of the mains input and you may need to replace some other components in that area which are designed to protect the monitor in just such an event as a power surge.

We didnt have a surge protector on our tv we purchased from home shopping net. and lihtning came in the line and i guess hit our tv can it be fixed or is it worth fixing price wise i hate to throw it away...


Look at the power supply module, most of them will have a surge protection devices (called MOV, same as used in common surge power strip but cannot handle big surge that power strip can handle) installed to protect minor surge, it should blow the fuse. Once MOV blown, it will more likely stay short circuit, if you put the new fuse in it will blow the fuse right away. You need to see if the MOVs blew up any sign of blown up components.
