Samsung HP-S5033

[daspyderman]

Would like to give more life to this 50" plasma that's done me well for quite a while. Will fire up but no picture, no sound. Tested all fuses, good, tried disconnecting both x/y mains, no change. Replaced power which I had, no change. Thought I had checked all the boards pretty well until I found this today (pic attached) on the Y-main. How to confirm this is the issue or other suggestions? Don't really want to order an $80 board for nothing. Thanks ahead of time for your help & time.

Can you turn the TV on and off using the remote or the TV's keyboard? Are there any flashing LEDs, standby light, etc?

Yes, yes and yes.

Ok. The fact that you don't have a picture OR sound seems to point to more than just the Y-main being the issue, if in fact the Y-main is faulty. I'm not certain of the similarities between the HP-S5053 and HP-S5033, but it looks like at least their sustains are the same:

I'd start by checking output voltages from the PSU. If the voltages are not normal at a particular connector with the load component connected (e.g. Y-main), I'd disconnect that component and see if the voltages come up to normal.

Thanks for the links. Will check that today once I'm home from my real job. Also, being a noob I'm assuming "sound" refers to from an external device. The tv does make it's normal startup noises but I'm unable to get sound through it with inputted a/v.

Sorry, been busy getting married.

Finally got to sit back down with this...
Checked voltage outputs with everything unplugged. All good.
Plugged everything back in (I thought) & same issue. Then realized the Y-main was still unplugged. Hooked that back up and started getting bad noises and voltage drops. Time to double check the caps on that I guess?

Re: Samsung HP-S5033

I have a Samsung HP-S5033 that has served me well. It's starting to show green tinges on the edges of everything. When it's been on for any length of time, the image starts to jump and flicker. Can you help me save it?
