HP monitor HPL2208w
Computer Using window 7 professional 64bit
Problem
Screen went black. Checked all connections satisfactory
Switched monitor off then back on. Full colour desktop showed for cira 1 second.
Did this a number of times
Changed monitors with another machine using Windows 7 home prem 32 bit.
Defective monitor showed same symptoms on other computer. the other monitor worked as normal.
Computer and defective monitor switched off for circa 9 hours. Switched back on monitor worked oK for around 50 min then reverted to blank screen with same symptom would only show screen saver for cira 1 second, before going blank / black.
Has been suggested elswhere the problem is that capacitors need replacing but have no knowledge.
Is it worth repairing? can only hp do it?
Or better to take to local repair shop? Thanks in anticipation.
