Pc not starting

possibly the filter...

If you need further help, reach me via phone at https://www.6ya.com/expert/thomas_092728000e6acb79

probably needs filters cleaning or a new lamp replacement.

Im not sure what to do so If i where you i would bring it to a computer store and see what they can do.

I just had the same problem, you have an idea on this?

Unhook the fan and see if the set works, it will work without the fan for testing purposes, chances are the fan is drawing to much current and is being shut down by the TV circuitry

Are they Long Beeps? Does the RED led light on the front show up?
If there is no RED led light blinking, then the problem is your RAM.
If there IS a RED led Light showing up, then the problem is your Power Supply.

I think below link can give ou step to replace or clean fan

Hi Kindly let me know how many times the red light blinks
Condition Code Service Actions Processor thermal protection activated. Power LED blinks red twice, once a second, followed by a two second pause.

1. Make sure the computer air vents are not blocked and that the cooling fan is running.
2. Open the hood, press the power button, and see if the processor fan spins. If the fan is not spinning, make sure the fan cable is plugged into the cable header on the system board, and that the fan is properly installed and seated.
3. If the fan is plugged in and seated properly, but is still not spinning, replace the processor fan.
4. Reseat the processor heatsink and make sure the fan assembly is attached to the heatsink properly.

Processor is not installed. Power LED blinks red three times, once a second, followed by a two second pause.
NOTE: This condition indicates a missing or improperly installed processor, not a defective one.

Make sure there is a processor in the system. Reseat the processor and verify that it is installed properly. Power failure (power supply is overloaded) Power LED blinks red four times, once a second, followed by a two second pause.

1. Check the voltage selector, located on the rear of the power supply, is set to the correct voltage (the correct setting depends on the region).
2. Open the hood and make sure the 4-wire power supply cable is fully connected to the power connector on the system board.
3. Check if a device is causing the problem by removing all attached devices (such as disk drives and expansion cards), then power on the system. If the system enters POST, power off and replace one device at a time, repeating the procedure until the system power failure reoccurs. Replace the device that caused the failure, then replace each of the other devices and confirm that they are functioning properly.
4. If you cannot isolate the failure to a specific device in the previous step, replace the power supply. **
5. Replace the system board.*

Pre-video memory error. Power LED blinks red five times, once a second, followed by a two second pause, and five simultaneous beeps are sounded

1. Reseat the DIMMs in the memory slots on the system board, then power on the system.
2. Replace the DIMMs one at a time to isolate the faulty module.
3. Replace 3rd-party memory with HP memory.
4. Replace the system board.*

Pre-video graphics error. Power LED blinks red six times, once every second, followed by a two second pause, and six simultaneous beeps are sounded. For systems with a graphic card:

1. Reseat the graphics card and then power on the system.
2. Replace the graphics card.
3. Replace the system board.*

For systems with integrated (on-board) graphics, replace the system board. PCA (system board) failure. ROM detected failure prior to video. Power LED blinks red seven times, once a second, followed by a two second pause, and seven simultaneous beeps are sounded. Replace the system board. Invalid ROM based on bad checksum Power LED blinks red eight times, once a second, followed by a two second pause, and eight simultaneous beeps are sounded.

1. Reflash the ROM using a ROMPaq diskette.
2. Replace the system board.*

System does not power on. No beeps or blinks since the system is not functioning. Press and hold the power button for less than four seconds. Perform the following steps depending on whether the hard drive LED turns green.

If the hard drive LED turns green, then:

1. Make sure the voltage selector (which is located on the back of the power supply) is set to the correct voltage for your region.
2. Remove the expansion cards one at a time until the 3.3V auxiliary light on the system board turns on. If removing a card turns the light on, replace the card and then see if the system works.
3. Replace the system board.*

If the hard drive LED does not turn green, then:

1. Make sure the computer is plugged into a functioning AC power outlet.
2. Open the hood and make sure the power button is securely fastened in the power harness and that the harness is connected properly to the power connector on the system board. In other words, make sure that the power button is making contact with the power circuit.
3. Make sure the power supply cables are connected properly to the power connectors on the system board.
4. Check to see if the 3.3V auxiliary light on the system board is not turned on, replace the power supply. **
5. Replace the system board.*

The following procedure will re-establish the communication link between the Headphones and the Wireless adapter, this is called "pairing". Before you start please make sure both the headphones and the wireless adapter are fully charged and turned off.
Note: The headphones and the wireless adapter come pre-paired from the factory.
1. Press and hold the power button on the headphones. See Figure 1.

Figure 1

2. Continue to hold the button down until the LED starts flashing red/blue in an alternating pattern. Release the button when the LED starts flashing red/blue. See Figure 2.

Figure 2
3. Once the headphones LED is flashing red/blue, press and hold the power button on the wireless adapter. See Figure 3.

Figure 3
4. Hold down the button until the LED starts flashing red/blue in an alternating patter. The LED will blink blue, then turn off for a few seconds then blink red/blue. Release the button when the LED starts flashing red/blue. See Figure 4.

Figure 4
5. Once both the headphones LED and the adapter LED is blinking red/blue, press the volume up button once on the headphones. See Figure 5.

Figure 5
Once the headphones is paired with the adapter, the LED on the headphones will blink blue once every two seconds. See Figure 6.

Figure 6
When the adapter is paired the LED will be solid blue. See Figure 7.

Figure 7
The adapter may continue to blink red/blue for a few seconds even after the headphones LED starting blinking blue. This is normal; the adapter may take a few additional seconds before the LED turn solid blue.
Once the headphones and the adapter are paired, it is not necessary to pair them again even if the batteries on both units are completely drained.
Additional Note: Repeated pairing will not improve the sound quality or give the headphones and the adapter a cleaner connection.

it is a bad fan. it also could be a power supply. Quite often the real problem is dirt clogging up the fan(s) to the point that they need to be replaced. Operation of the set in a dirty environment is not a good idea
