PHILIPS 43PP920217 DPTV305, no video feed after Conv IC Install
Essentially, got the tv for free, the convergence was all messed up so I replaced the factory STK392-120's with the same ones put the thing back together and now i get all my projectors lighting up but can't get any actual video feed out of it. I can change channels and hear them fine but no video feed other than a mix of the colors with no changes. So I guess I'm trying to figure out where to go next, I checked over all the boards for blown anything but can't find a single thing wrong. Anyone have any ideas where to go next?

Re: PHILIPS 43PP920217 DPTV305, no video feed after Conv...
You should have used 180s for replacement,and check all low ohm resistors near ics.And alot of time when you replace them you have to have service code to be able to Factory converges and realine.Need help let me know.

Your flyback has failed most likely...bad new is they are nearly impossible to find, This is a known issue on most of the models below. The site Tv Repair Kits can sometimes get replacements - but its not often.
This repair kit is known to work on Magnavox TV sets with the following Chassis/Model Numbers.
The convergence ICs and resistors have failed. You will need to install a convergence repair kit. The Phillips DPTV305 chassis convergence repair kit is the correct one for your magnavox. Its available at www.tvrepairworld.com and the kit contains the 2 ICs and resistors and the CD with repair instructions.
Install the convergence repair kit. The Phillips DPTV305- DPTV345 convergence repair kit from www.tvrepairworld.com is the correct kit for your model. The kit contains the two ICs and the 12 resistors plus the CD with repair instructions.
Thats a convergence issue. you will need to replace the two Convergence IC and quite possibly a few of the 6.8 ohm resistors. You can get the phillipd DPTV305-DPTV345 convergence repair kit from www.tvrepairworld.com the kit works for your model also and it includes the ICs and resistors plus the CD with detailed repair instructions.
the DPTV305 - DPTV345 convergence repair kit at the following link should repair that issue. The kit includes the replacement parts and a CD with detailed repair instructions. http://www.tvrepairworld.com/
you may find the schematic but the chips inside is mcu IC with clock. the schematic usually compose of infrared led, limiting resistor, micro, switch and clock. this is tv, what possibly you can do is buy a universal remote control or another philips tv remote control. hope this help. regads, cebuwano
Convergence circuits have failed you can get the DPtv305-DPTV345 convergence repair kit at the following link. The kit contains Both ICs and all 12 feed resistors plus step by step instructions on how to do the repair. http://servicemanuals.vstore.ca/
replace the convergence Ics and feed resistors. You can get the DPTV305 -DPTV345 Convergence repair kit at the following link which contains both ICs and all 12 feed resistors plus step by step directions with pictures. Here's the link. http://servicemanuals.vstore.ca/
