A month ago through Ebay I bought an OHP Eiki OHP-250M with 250W AC metal-halide lamp inside. I was glad about it not so long. Yesterday I could not start it.
When I turned on my OHP, I heard a high frequency noise made by high voltage board. Inside the lamp I saw a dim blue arc but lamp had not started.
I don’t know what trouble with. May be somebody had such experience? Should ballast make a noise if lamp is faulty? May be the problem is with a ballast? Or lamp cause it.
Please help me!
