Phillip's model 52pfl7422d/37 chassis Q523.1U_L service manual needed

[reddsta87]

I'm trying to repair the SSB board on my Phillip's 52" Tv that all the HDMI ports don't work. I discovered what looks like a voltage regulator with capacitors surrounding it blown off and discolored. The Ceramic capacitors and what appears to be voltage regulator have no part numbers on it so I can repair. I part number for the SSB is 3104.303.50842-D. I'll add a photo of the spot in question but more need the schematic so I can get the correct components to replace. All help greatly appreciated

I found it it 2 seconds using google

If you are talking about the service manual for the Q523.1 then thank you for telling me but the layout has nothing indicating what components are on the board or schematic. I've been repairing electronics for 9 years. Don't patronize me when I've already called Phillip's and my local tv repair people, the forums, shopjimmy and just about exhausted every resource available before posting on this thread. Please save your snarky comment for someone who deserve it. Thanks

The why the fuck did't you mention it in your post. Good luck

I only have the schematic for this board

All the information the mods asked for were included in my post and I thoroughly describe the type of information I was looking for. If that isn't enough to have the first reply be somewhat respectful then I'm at a loss. I'll wait for someone polite to answer my inquiry. Thanks again

Do you know how many people come here without even checking for things themself? or even bothering to do a search to see if the problem was already answered in another thread?
Had you said you downloaded the manual and it did'nt have the information, ie schematic it would also same others from searching for it only to get the same answer you gave me.

Look I've been on the phone an online for hours looking for the schematic only to have TV repair professionals tell me that "no one does component level repair anymore" and "robots put those small components on there so I can't help you". I've read through the Q523.1U_L manual not seeing anything about 52pfl722d/37 or 3104.303.50842 mentioned anywhere. I exhausted every legit way to find it without posting here. I'm tired, I'm frustrated, I'm confused, and I'm doing this all at work on my cellphone when I get a break. I just needed to see the schematic to make sure that those components tie in with the hdmi and what rating the capacitors I removed were, so I can replace. It's a simple question that has taken me much longer to answer than most problems I run into so forgive me for being short. I didn't want to bore everyone in the forum with my personal problem so I omitted what I had done already.

But while I apologize for being short I don't for the treatment

I discovered what looks like a voltage regulator with capacitors surrounding it blown off and discolored. The Ceramic capacitors and what appears to be voltage regulator have no part numbers on it so I can repair. I part number for the SSB is 3104.303.50842-D. I'll add a photo of the spot in question but more need the schematic so I can get the correct components to replace.

I clearly ask for a schematic and even give the board part number and say that im trying to find components. Had you not read my opening paragraph you might not have known that.

That device in question 7B06 is the power MOSFET for +5V-STANDBY @Source pin.
See block diagram on PDF page 57.
See schematic on PDF page 75.
There is a fuse feeding that MOSFET.
The 3104.303.50842-D is the blank PCB P/N
The service manual for that section of the power supply is more than close enough to check that standby power supply section to see if you have +5V-STBY or not.
