I'm trying to get a Philips tv up and running. It's model 27PT6441 chassis L04.1U AA. Diode 3503 is in need of replacement and I'm having a problem. I can't seem to find a replacement any information on it, any parts I can substitute etc. On the service manual it's listed as part 4806 209 87877 but i can't find it online. It says it's a DSP301NA21F. Can anyone help me out, what are it's specs, can it be substituted with something else?. It also has three colour bands orange,black and blue or maybe it's the other way around blue,black,orange? I'm not too familiar with this. Can someone please help me out?
In Philips chassis (this one) all diodes begin with 6 then number. you are describing a resistor number 3. And i looked up the part, it is a spark gap. this is just to help prevent a power surge from destroying your set, 3503 is not necessary to the proper operation of the television. if it is burnt, the tv took a voltage spike, or lightning strike. You can't get it because there is no demand for it. you have other problems. if you took a hit.
Check the bridge rectifier 6500. and 7512 i bet you will see that 7512 is shorted.
The part number does not jive up with the manual either. - re-check your numbers. may we are on the wrong page
