    Bush TV cross Phillips?

    Got this TV a few weeks ago, standby led goes from red to green contiguously, back lights do not come on or anything else for that matter.
    I've been looking for service manuals but only found a schematic for the PSU, the TV front logo is Sansu but no info on the web, the main board seems to be a Phillips and the PSU is a Profilo telra.
    I have replaced all the 25V/1000 uf caps as some were swollen and also the 16v/2200uf caps, managed to fit one reverse polarity and it went with a bang!
    C322 has a reading of 25 Ohms which the lowest on the board although its a vent cap. There is also a stanby transformer to verify.
    All fuses on the inverter board are good and as with the caps so think the main issue is with the PSU??

      Is it Sansu or Sansui - which did you search


      Have you replaced or tested the startup cap

          In Pic 3 on right hand side near the no 5 there is a right
          angled trace looks burnt through?

          On pic2 there are other odd looking bits if you can get a clearer pic without flash would help one is on the right hand side near the 24v connector the 3 legged device attached to the L shaped heat sink- another is the brown spot going straight up from pin 7 of that connector.
          Please can you update your country in your profile.

              Got admit I haven't replaced it or identified it, have been checking all the caps for low Resistance and replacing swollen ones so far.

                  Got a situation here that I would appreciate you'all pros to have a look at! My buddy's 37" Amstrad blew an IC on the PSU and I read that replacing the IC does not solve the issue.
                  I have not cleaned or done anything to the board but as one can see the soldering is pretty poor.
                  I was going to start a new thread but notice this board is similar to the above Telra on the 32".
                  What would be an easy fix here, buy a kit or junk the board?

                      Help with Bush Tv (Vestel 17mb95m Mainboard)
                      by FlailingEngineer
                      Hi, I was recently given a Bush Smart TV by a friend and the main board seems to be hanging on by a thread.

                      Before we get to that, my first obstacle was figuring out the model number since the back sticker has gone for a walk. Upon taking off the back case, I noticed the following Vestel parts, 17MB95m mainboard, 17IPS71 (what I'd assume is power supply) and a VES420UNVL-3D-S02 display panel. After doing some research I think the TV I have is a Bush ELED42240FHDCNTD3D, based on the matching image here (https://www.manualslib.com/manual/11...td3d.html#manu...

                      Need help identifying an IC chip on a Bush DAB radio (BD-1801)
                      by tyler123456
                      Hi,

                      Not sure whether anyone can help but I'm trying to identify the IC chip in the photo below.

                      I purchased a faulty Bush DAB radio (model # BD-1801) and identified that an IC chip was blown on it. Unfortunately, I couldn't read the manufacturer name / model number of the IC chip.

                      I purchased another (working) BD-1801 so that I could open it up to find out the IC details - but the IC chip details are missing (as you can see in the photo.)

                      Given the two huge blobs of solder either side of it I'm guessing it regulates power(?)

                      Anyone...

                      Bush WI-1810 Internet Radio
                      by Johnny.p
                      I recently bought an internet radio Bush WI-1810, it came with a power supply that when plugged in promptly damaged the radio. I discovered too late that the radio was 6v and the supplied adaptor was 12v. The radio still powers on but the wifi is not working. I have attached a few pictures- Image 2 showing the board with damaged component top right labelled U8. There are several other similar components like U9 (image 3) that I'm wondering could be a replacement.
                      U9 has a code on it S5EJI- I have searched several smd code sites and the nearest I can find is for a mark of S5E -listing shows...

                      Service manual req Phillips 75PUS6754/12
                      by learnmore
                      Hello Community,

                      Would welcome any help on getting a service manaula for the above model (Phillips 75PUS6754/12) TV or anything similar.

                      Picture intermittently works fine for a day or a minuite then goes off, but backlights appear to remain on.

                      I thinking troubleshooting TV or using a tape method on the panel but would like some guidance on tracing the signals accurately rather than a trail and error.

                      Thanks in advance,
                      LM
