Philips 26pfl5302d/37 dead

[shelby5041]

Hi picked up this tv for free

No standby light

Wont power on

Seems dead

Power supply caps all visually look ok....i get 5v standby voltage to the front led board....if i 5v standby but the standby light is not on i,would imagine its a bad main?...

did some brief research seems this tv had common main board issue....the 26pfl 32pfl 42pfl 5322 5332 5302 series

Any input on this?

"i get 5v standby voltage to the front led board....if i 5v standby but the standby light is not on i,would imagine its a bad main?..." That is the right direction, and you probably do not have switched 24V output either.

The ps pins are not labeled ....but i tested all the pins and only can get a 5v standby only....if i recall there may have been a couple lower voltage like .2 or 3v but not sure....i just know i did get a 5v and nothing higher

I the found the service manual but is too confusing to me

I do think itbseems to be a main issue rather than ps issue

I can get a main for $20

So im thinking of buying it once i got an expert opinion like urs

Thanks

Imwant to fix this tv because its cool looking white body..and its smaller 26 inch and has hdtv tuner built in would be great for kitchen or bedroom and has usb port for pics and music.....this tv has a lot of features....seems like a lot of entry level tvs nowadays are junk made with no features.....ans thats why they are so cheap priced

You have 3A on the main board, and lots of lytics caps.
Check the fuse, try heating and cooling the board and see what happen.
It also has some switching power supplies on that main board and lots of MLCC (Multi Layer Ceramic Cap) I.E 2U22, 2U25, etc. that you should check to see if they show low resistance reading or not.
If you can get schematic that will help a lot.

Thanks...i checked all fuses previously..all good

Also here is a piece of information that may be relevant

I got tv free..when i opened it up the left inverter board and main board were missing all,mounting screws .and all,cables to them were disconnected.....assuming someone previously was working on it...all other boards were mounted properly

So im not sure of what was done

Re: Philips 26pfl5302d/37 dead

would imcheck the multi layer caps in circuit and with tv unplugged?...using ohms setting?
