Re: Samsung plasma pn60f5300 -- no picture-- bad panel ??

Update on my tv. Couldn't wait any longer for pointers on what to check next, so I took it to a shop. They said it is a power board issue. They are going to get a kit and upgrade it. $280 is my quote. I think they are just going to replace some capacitors and call it a day. Thank you for the information and help.

Re: Samsung plasma pn60f5300 -- no picture-- bad panel ??

Green LED blink is every 7 seconds.
Va and Vs briefly 208v when X and Y boards are connected. Vs and Va 208v constant with them disconnected.
No glow on panel that I can see right now. Will check at night to make sure.
Checked buffer board. Watched video link in previous post. No shorts.
How do I check Vsch low, Vsc short, Va short, Vs short on X and Y board?
History of fault is tv started to not turn on sometimes. Started one month ago. Until it would not turn on this last time.
Thank...

Thank you for taking the time to help me Tom. I always disconnect power and wait for voltage to drop before disconnecting anything. All voltages good until x or y main board connected. Also wait for voltage to drop before connecting anything. Then power on. No cracks on panel. Jumped 3-4 and nothing on screen. No bulging capacitors. Green LED blinks on main board. Tv responds to remote.

I did check the panel. No cracks found. I've been testing more and found when I disconnect the y main board ribbon and x main connector to
Main board, Vs and Va stable at 208v. Romoved y main board from buffer board. Same result when ribbon connected. Drops to 10v. Disconnected upper x main from bottom x main and same result when connector connected from main board. Checked buffer board. No shorts to pins. Checked y main and x main, no bloated capacitors. What else do I check on the x and y main boards?...

I have the same problem with my pn60f5300. Started to not turn on and red led would blink, then stop. Finally won't turn on, just the blinks. 10 or 12 long then 3 short. Removed back panel. 5v and 15v are good. Vs-on sends 3.3v, then goes to 0. Vs and Vs have approx. 180v when vs-on has 3.3v, then gradually go down once vs-on goes to 0. Blinking green light on main too. First time working on a tv, but am comfortable with volt meter and pin testing. Any suggestions or help would be appreciated.
