SOURCE: says no signal when switched to hdmi when there is one.

Have the same problem with a 532H - but here is what I did to resolve the issue:
1) Click your Menu button on the TV remote.
2) Go to Screen (click the right button)
3) Go to Main Picture Source (click the right button)
4) Select HDMI (click the Menu button when done)

SOURCE: Cannot get a connection with HDMI input

When the tv won't scroll to the HDMI inputs, it means that the tv does not detect a signal on those inputs. This either means the tv has an issue and can't receive an HDMI signal(very unlikely) or there is no signal being sent from the source(converter box) The first thing I would do is unplug all output connections from the box except for the HDMI output and see if this gets rid of your problem. If not, I would be more inclined to think you have a problem with your converter box than with your TV. You could also try using the HDMI ouput of a DVD player if you have one.

SOURCE: Philips LCD TV "47, model PFL 8404H/12, NO SIGNAL on all 4 HDMI

This is quite tricky as it was working until last night and suddenly stopped receiving signals. What can happen wrong?
Do you have any other Player or other HDMI cables to try out. Sometimes the cables would be damaged or PC may fail to detect the HDMI.

Try this out from Philips helpdesk where there is new SW and FAQs are available.

Let me know if you are not able to upgrade the FW (if you do not get the support on ugprading)

When I switch from one HDMI input to another I get a no signal & spinning LG box. after several minutes it gets a signal


Try a different HDMI cable, then try the other HDMI inputs on the TV, then try to connect another HDMI device to the TV. If all are still bad main board needs replaced

Why is tv saying no signal?


Connect a known working DVD player by using a new HDMI cable to HDMI INPUT 1 and check for signal.
If you have a DISH or CABLE system box, connect that also with a new HDMI cable to HDMI input 2 or 3 and recheck for signal. Your T V remote will have an input selector to change between the different inputs on your
T V.

LC-26DA5U 26 in. HDTV-Ready LCD Television: i connect a hdmi cable 2 my hd cable box - the pic...


The cable box needs to be set to send different signals when using hd tv and standard tv. Usually a good setting would be 720p in hd and 480p in standard. The tv is working fine it is the cable box sending the signal. If you have another hdmi source such as a dvd player you may hook that up to show the tv is working just fine.

"No signal" sign on TV screen using HDMI selector


it sounds like a refresh issue, double check you selector and make sure it fits the refresh of the tv. i had this once with a sharp where the tv was 120hz and the selector was 60 and it created a no signal and when it did come in it was jumpy. if you have a 120 tv then selector should be the same.

I cant figure out how to plug in the direct tv cable


Ther is no "cable" connector on this model tv. Check your direct tv control module "cable box" for a hdmi output. If you have that output, you will need ahdmi cable for HD broadcast. If you donot have a hdmi output on your direct tv box, contact direct tv for the right one. Do not use RCA connectors because the picture will be fuzzy do to in-ability for rca connectoe to send HD signal. You MUST have hdmi signal from cablle box to tv.
Good luck.
