I am having an issue with the tuner on my set. The tuner has always had trouble picking up a few channels during search that my other sets could pick up fine. Sometimes it would pick up these stations on one scan and lose them on the next. The other day I tried the channel setup again and it could no longer find any stations at all, even stations that were working minutes before. Is this a tuner issue, main board?

I can hear Fred Sanford now...."YOU BIG DUMMY".....I pulled the "F" connector out of the tuner by accident. The tuner number is BN40-00248B. Low and behold I had a scrap board with tuner number BN40-00248A. Although the tuner is different (according to Encompass.com) it's footprint on the board is exactly the same as the 248B so I decided to de-solder the tuner off the scrap board to see what I was getting in to.
As you can see in the picture the terminals and solder pads are super small. No matter what I tried I could not get either the terminals or support... -
Hi All,
I have a 20+ year old Sony ST-S320 tuner that 'forgets' saved staions from memory. When I opened the case I was hoping to find a battery that could be replaced - but none was present.
I've attached the service manual. Can anyone point to where I should be looking to fix this problem?
Many thanks.

Hello everyone,
I have a rather strange problem with this Philips I just repaired.
The set came with startup problems, I checked the PSU, found some puffed caps, replaced them and now it is starting perfectly.
According to the philips website this tv should be equipped with a tripple tuner.
However there is no option to scan for satellite channels in the menu.
It only shows the option to search for DVB-T or DVB-C channels.
The set is equiped with the F-type connector in the back so to me it looks like it is indeed equipped with a Sat tuner.... -
My Marantz 120 Tuner stopped receiving Stereo signals. It works fine other then Stereo. I have a fully loaded shop here with all test equipment except and RF signal Generator.
I get great reception on FM so I have used that signal troubleshoot. I have been all over the MPX board and replaced all caps. Also the entire power supply caps were replaced.
All Voltages on the MPX board are good... all Transistors Good...All Diodes Good and other components.
The stereo lamp is good as I powered it up and it lights. The signal flow to that lamp is unbelievably... -
Hi,
Sorry if I posted this in the wrong forum.
As mentioned in the title I'm looking for Philips SAA7134 TV tuner card driver and software. Sadly I couldn't find anything online. Maybe someone here has them?
