I returned from work yesterday and my monitor was completely dead. No power light - no nothing. It is only about 5 months old and showed no signs of deterioration. I tried new outlets, power cord, etc. to no avail. Any ideas of the cause or a fix? Thanks!

Building on ’s warranty suggestion and the points raised by , here are practical, safe next steps and what to expect from a repair shop so a quick decision can be made without repeating earlier troubleshooting.

A reputable shop will first confirm model/serial details, then test the AC inlet and any accessible fuse, measure DC rails on the internal power board, and visually inspect for burned solder joints or bulging electrolytic capacitors. If the monitor uses a separate inverter or external brick, those are checked next. Ask any shop for a written diagnostic report and a parts+labor quote before authorizing work.

If considering DIY (only if comfortable with basic electronics and mains safety): unplug the unit, wait for capacitors to discharge, document how panels and cables are removed, and inspect the power board for bulging/leaking capacitors or burn marks. Replace failed capacitors with the same capacitance and equal-or-higher voltage rating and low-ESR types. If the failure is an inexpensive, modular board (power board or inverter), replacing that board is often simpler than component-level repair. Do not attempt high-voltage parts (CCFL inverters or CRT flybacks) unless experienced.

Practical decision rules: obtain the original purchaser’s order confirmation if warranty is needed — manufacturers typically accept proof of purchase even without online registration. Get a written repair estimate: for low-cost panels, repair seldom makes sense if quoted above roughly half the replacement price; for higher-end displays it often does. Always prioritize safety and dispose of unrepaired units through an e-waste program.

Just one suggestion for fixing it - Send it back to supplier - get them to replace.

That makes sense -- but, unfortunately I bought it from a co-worker (new in the box) who bought it on line and never used it. He didn't register it so it probably isn't warranted. I'm thinking it is probably a simple short or something -- but I can't even figure out how to open it! Is it a waste of money to take it to a repair shop??

It should not matter if it was registered, but you have to get your coworker to conatct the supplier and arrange to get it replaced/fixed. Most monitors are replaced under warranty.

There is nothing you can do if you open it up.
