Reply With QuoteSounds like a logic fault ,when you say no signal do you mean no antenna connected?. I'm not sure if this is the model that has the digital board fault, if it is Philips do the exchange for $154.
Bloody Phillips TV
hey guys I have a Phillips TV
Model Number 29PT2252/79R
Chassis Number LO1.1A
It works, turns on and sound all good with no signal input
BUT as soon as I hook up the A/V to it it turns off in about 5 seconds
I turn it back on and dies again in 5 seconds
But if I turn it on with out the video input just the audio it keeps going
Any suggestions ?????
Could it be the High voltage tuning caps near the flyback ???
HELP LOL
One more thing what does the Q7450 (BC857) surface mount transistor
it's up near the fly back side of things ???
Cheers

Hi B4L, mate, did you forget we're philips agents
right lets get started
1. what did it come in for eg no go, screen probs what
2. what have you done so far
these sets dont have the SSB (small signal board) but could still be software
have you put it into SAM or service mode (on cust RC with tv in standby pres 062596 then "i", now you have to press quickly, all buttons MUST be press no later than 0.75/sec between presses, best to practice hitting the right numbers before trying on set), if so what errors were detected
Q7450 is a shut down switch driven by Q7561 which in turn is driven from the opto circuit which is controlled by 7520 PSU pwm controller
try that lot and we'll go from there!
post results B4L, we'll fix the bugger, philips are FUN!
When I explained to the guy what avatar I wanted, that wasn't what I meant!
ON FURTHER RESEARCH
replace
7461 bc337
7463 bc327
2455 47uf 63v
remove 2615 1nf cap off pin7 of 7602 eeprom
do all those first if unit still faults go into service mode (previous post) check for error confirm options are
176 247 193 168 236 212 044
any errors post them and then we'll go in depth LOL
we havent yet!
oh by the way, these f**ks have a piss arsed G2 prob, if not adjusted DEAD RIGHT/SPOT ON it will cause the same symptoms, try adjusting screen slightly

I will have to dig up a remote i must have one here as it's been a while since a Phillips TV has left here working ROFL

But with a bit of mucking around the pic is back
cheers
