Re: Digihome 32" LED TV

I have an issue with a Philips 32PFL3008T, where the power board type is 17IPS19-5P. The TV is working, but I get no backlight (i.e. screen looks black but shows content when lit by flashlight). Is it the same powerboard that handles the backlight and do the advice in this thread apply?

Possibly Led failure do you have 24v ?

Re: Digihome 32" LED TV

I have this same power supply board used in a Telefunken set relatives gave to me to attempt repair. Same problem here: TV is dead.

So far I've found the schematics here.

But be aware that the board we have (mine is identical to the pic posted here) is a bit different from the schematic: they simplified the circuit and omitted some parts to save costs, so it becomes harder to nail problems.

Re: Digihome 32" LED TV

Hi guys i have a faulty Vestel 17IPS19-5 installed in a Hitachi 32XHC01.The initial situation was a tv completely dead. After replacing the three top diodes SB5B0 (one was bad) the tv turns on again but i still have a little problem, a loud buzzing noise coming from the L502 component,

Turn down the brightness see if it goes.

Nothing changes, the noise is still there constant

Re: Digihome 32" LED TV

Just to add to the great info above, another Vestel 17IPS19-3 here, in a Finlux 26" FIN26LEDHDR, with the 3 SB5B0's at the top, and 3 UF5402's towards the bottom.

Found one of the SB5B0's (nearest the transformer) to be shorted, the other 2 were ok. Replaced the shorted one with an SB5100, and the TV powers up ok. Will replace all 3 with SB5100's.

Haven't tested the 3 UF5408's. Has anyone found any of these to be shorted at any time? Might leave them if not. The set is easy to work on if they do eventually need to be done.

Re: Digihome 32" LED TV

Hi all had the same problem the diodes are coming out at 0.00 - 0.02 up and down. I noticed this isn't a very recent thread but I usually get my diodes at work and have never had to actually go out and buy them. I've tried an online search for where to buy the diodes for this board and have so far come up with squat. Can anyone help?

Wow ok didn't click all the way to the last page so I'm referring to the vestel 17ips19-3 board from an earlier post

i try to use the likes of rs or cpc for parts but most have minimum orders so yes ebay is ok for the odd orders like this your local maplin store may have these parts in too some stores are better than others though.

Re: Digihome 32" LED TV
