Question about Dell OptiPlex GX270 PC Desktop
Comp was plugged into surge protector box. comp was in standby. Also plugged into surge box was guitar amps and pedals, etc. being used at the time when surge box started making high-pitched sound - alarm? So turned off everything plugged into surge box EXCEPT for comp. Then turned surge box off and back on and discovered comp will not power on. No LED light, nothing! (Yes, everything else plugged into the box still goes on).
Have tried hint from Dell of unplugging comp and holding power button to discharge flea power and then plugging in comp directly to wall outlet. Still won't power on. Hope you can help! Thanks
Try unplugging the power cord from the PC and the wall outlet or whatever it's plugged into for a couple of minutes and then reconnect both ends. I've seen this fix a lot of PC's that wouldn't power up after a power fail.

Gerry is probably correct. Try it without the surge box, if that does not do it change the Power Supply. You zapped it with a petty big surge with all the noise etc. Run your computer on a seperate connection. The power amps can feed back via the power line. causing all kinds of problems in the computer.

I would suggest replacing the PSU (Power Supply Unit).

The Standby/Power light of the TV blinks when there is any internal malfunction in the TV.
The self-diagnostic function of the projection TV will cause the STANDBY light to blink or flash when the television detects an issue. The number of times the STANDBY light flashes corresponds to a specific issue. As per the two examples below, some of the issues may be resolved without the need for service.
If the STANDBY light flashes three times in sequence, the lamp cover is not securely attached. Reattach the lamp cover to resolve this issue.
If the STANDBY light flashes four times in sequence, the TV may be overheating. To resolve this issue, ensure that the back of the TV is well ventilated.
If the flash sequence is not listed above or the light continues to flash, follow the steps below to perform a power reset:
Try the following steps to check if the issue can be resolved.
Turn off the television.
Unplug the television power cord from the electrical outlet.
Let the television remain without power for 60 seconds.
Plug the power cord back into the electrical outlet.
If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
If the issue continues to occur, service may be required.
Thanks for using Fixya.
