It is a Pn64e533, a 64inch. If you connect ANYTHING to the power supply, the relay just clicks at 2 times a second. I don't understand how the voltages can be close to spot on when ps on to gnd and vs on to 5v are wired up. I only replaced thr 3BR2565JF and the two 18n50 mosfets. I removed the two I substituted for them(22n60) with originals. Still had same symptoms....

I did test it on the workbench first. The vs is 220. Tha va is 55. I also have the 15 volt rail.

I have all the voltages until I hook up all connectors then the relay just clicks on and off repeatedly....

I have one from a pn64e533. I replaced the 3BR2565JF and the two 18n50 (used 22n60 that I had on hand). I now have standby, vs, va, and 15 volt rails. When I reinstall it the relay just clicks. Swapped it out with a good power supply and the tv works. What do I have to do now to repair it?

Check the igbt's under the y-sus board for shorts. They are labeled with a "Q". It is strange that you have the correct voltages.

Re: Samsung Plazma Blues Model PN59D550C1F
Start by replacing these 10uf 50v caps. They are on the y-main board....

Re: Panasonic TC-P65V10, Plasma
Take a look at the 5 big blue capacitors on the ss board for cracks on any of them .

Meritek capacitors
Are Meritek capacitors known for good quality? I'm interested in the 10uf 50v 105° electrolytic radial ones for use on Samsung Y-mains.

Re: Lg 50pk250
It's been along time and I can't remember who I bought them from. Ebay doesn't go that far back for me to check either. My advice is order from someone that posts a picture that looks like the original and takes returns. I explained that I know how to test them and then they refunded my money without having to send the fakes back to them.

Re: LG 60PV450 Sound No Picture
Look under the z-sus board for cracked solder joints under the 3 copper coils. I think that is your problem. Make sure you install ALL screws in the board before turning it on.

Re: Lg 50pk250
The new ones are probably fakes from China. Always test new ones before installing.

Re: LG 55LE8500 the legendary TV is off. Help
The cpu under the heatsink needs to be re-balled with leaded solder balls. You can heat up the cpu with a heat gun for about 45 seconds and see if it comes back on, but this will not fix the problem for very long. The cpu is on the mainboard (where all the inputs like HDMI are).

Re: Panasonic 50st30 plasma tv, where do I need to recap?
Check the screws that hold down the SC board. They may be coming loose. If you download the service manual you can enter the menu where you can adjust for aging. You can set the VS high or low. Elektrotanya.com has the manual.
