Without a schematic, I would look for the 8 and 13 volt regs,but they might be high because there is no load.Where would you get a schematic in Belgium,if i may ask?Can you compare the crt voltages with a similar crt?Thats where I would start for no brightness. My advice may be all wrong if you use a different system there in Belgium,since I once heard the screen is black in England with no signal,so who knows? May we have some details, as to size of set, and whether PAL system is high bright without signal,or black? Good luck.al Al Leatherman 224 Rt. 46 Mine Hill, NJ. 07803 973-361-5796 WWW.ALS-TV.NET ----- Original Message ----- From: "Stefaan Van Slycken" <vanslycken@xxxxxxxxxx> To: <techassist@xxxxxxxxxxxxx> Sent: Monday, June 09, 2003 5:05 AM Subject: [TechAssist] Philips CTV MD1.1 lightning > This is a philips CTV set with MD1.1 chassis (which is a lot like MD1.2, MD2.1 and the like), struck by lightning. It was switched off at the time. > I get a green light, Horizontal and Vertical signals are present but screen stays black. I get a DC voltage on the R, G and B taps of the CRT. I put the tuner PCB (with IF, PAL decoder etc) in a good TV and it worked fine, so that's not the cause. I notice that the "+8V" and "+13V" are 11V and 15V respectively. I have no schematic or other voltage indications I can refer to. > Any help? > TIA > Stefaan Van Slycken > Van Slycken Elektro - Waasmunster, Belgium. > > P.S.
