Do you have such black drops on the back of the board?

Reflowing is a short-term solution, the tin is porous and does not improve with heating. Reballing is the best solution if you want a good repair. Yes, there are motherboards that still work after a reflow after half a year, but most of them don't make it.

But before reballing, you need to carefully remove this black compound, there are small solder balls inside it and when heated, the solder melts and closes inside the components (capacitors, resistors ...).

Thank you for the great tips!

Do you mean that the processor would be faulty after overheating or do you mean that the cooling must be fixed too? I don't have anything to lose (except otherwise fine TV) so I think I'll go with reflowing and better cooling and try my luck. Or do you have something better idea?

Good to know! I didn't even think about those blobs deeply. And yes I do have three of them as shown in the picture. Do you have tips how to remove that black compound? I watched some videos in which they used hot air and careful scraping to remove it.

Yes, you have to be very careful with these drops, you can damage the elements and tracks!

before 4-5 years.. i was out to visit friends family and was his grandma have this philips Main Soc usual BGA issue... and there nothings underhand... and i asked if this will not succeed then need to buy Boards or new TV.. she agreed.. then i used Cloth Iron she had really nice heavy with out Steam..LOL put wet cloth on the Soc. and let the Iron heat to its last degree then just put it on the cloth with out move for about 5-6 minutes.. the Tv start working... but later one year or more they told it back to same fault lol

Cool, a year from an iron refow, thats great, MacGyver would be envious. https://www.imdb.com/title/tt0088559/

I'll try my best!

Yes, this camera is very sensitive! My camera is Guide IR PC210. I did quite a lot of research before acquiring. I found this one providing best bang for buck in a "budget" category

Sounds like something I should have gotten when my MSI B450 Tomahawk was still working! I think the MOSFETs failed! (or whatever they are called)

Decent thermal camera is expensive but crucial in some situations. It's good for monitoring slight differences in temperatures and also tracing faulty components while injecting voltage! What did you do to that motherboard? Did you try to repair it?

[sordids999]

I'm trying to repair this TV totally dead D501(T2D34 diode) is showing as shorted in circuit and out
Zd501,zd504,zd505 shorted in circuit but out of circuit there fine so stuck on trying to trace what causing the fault any ideas
Thanks

[William1967]

Find the error on the mainboard, start the SDM and see how many times the LED flashes.

[sordids999]

Found T2D34 diode is shorted and B117H is also shorted
Ordering B117H but can't find T2D34 diode does anyone know and alternative ?

[lotas]

And what's wrong with T2D34? It's not a simple diode, but a protective, bi-anode one, and you can't check it with a simple multimeter.

[lotas]

Your diode belongs to the ST02D series, the exact name (voltage) depends on the marking, its marking depends on the color of the inscription on it.

You can replace it with P6KE SERIES, but you need to know exactly what voltage you have.
