Have TV Questions? Ask a TV Technician
Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.
Sorry to hear you’re having trouble.
This is almost certainly related to a bad lamp. The cheap generic lamps have very high failure rates and can cause these symptoms. You really need to replace with the proper OEM quality philips/osram lamp for confirmation though.
There are other possibilities like a failing ballast or power supply fault, but if it was working fine on the old lamp, that is much less likely.
Those things both point to lamp issues,
if even the new lamp doesn't do it, then a bad ballast or power supply is the most likely cause (still lighting but not getting enough power to be at the proper brightness)
That is something that will require repairs. Hopefully you don't have much invested in it other than the lamp costs, because these tvs get expensive very quickly, and generally wouldn't be considered worth the cost. It would be cheaper to buy a new LED tv in the long run than to repair this one. It just isn't worth the investment for a 10 year old set.
If it comes to that, I can certainly help with parts, repair shops, or replacement recommendations.Let me know how the lamp works out when you have a chance.
