Hi
I'm a retired Electronics Tech.
Used to repair Crt TV's
First time posting
I Have a 2006 Insignia 42" plasma NS-42EPTV internally an LG PDP42V7xxxx
My first symtoms were like the slow startup thread on your site.
When powered on screen was (black spray painted) over about 3/4 to 6/8 of the surface. picture was/is good where ever the pixels weren't black.
Over approx. 2-5 minutes the black pixels would slowly turn to a good picture.
TV ok after this until turned off.
Checked voltages via internal labels
all 5VA=5.2v Va=65v Vs=187v
187/-80/120/n.a./165
I assumed -80v was the -Vy and the 120v was the VSC and
the 165v the ZSUS voltage. all as shown good.
Did not notice any bad caps dryed out or ballooned.
Sorry no picture of screen due to new problem arising see next.
When TV is powered on, red light turns blue as normal some OSD display, but as sone as HDMI input switches on, the light go red and Tv is off. Also the red led on the power board LED601 in on. I have to cycle the power to reset so I can try again.
Also with no picture input and turned on the TV will stay on and the OSD and Menus can be scrolled through.
Any help would be welcomed.
