No voltage feeding the convergence ic's. - Philips 50P8341 50" Rear Projection Television

did you replace the low ohm feed resistors with the ICs?

You have bad convergence ICs. There are 2 ICs in the convergence circuit, one is for the Blue the other is for the Red. You can buy 2 ICs for under $40.00. Replacing these ICs require soldering and desoldering skills. Sometime, the resistors in the convergence circuit go bad also. Be very careful, there is a very high voltage in a CRT projection TV the voltage is over 30,000 volts.

mo you can replace the two Convergence ICs and check the 3.9 ohm feed resistors. You can get new replacement ICs and resistors at the following link.

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.

your convergence ICs have failed. You can get the convergence repair kit for your model at the following link which contains both convergence ICs and all of the feed resistors, plus the kit contains step by step instructions with pictures on how to do the repair.

those are the convergence feed resistors. # blinks on a panasonic means convergence IC failure. You will need to replace the two stk392-110 convergence ICs and the six resistors. You can get replacement ICs and resistors at the following link.

Hard wire jumpers feeding voltage to convergence circuitry located between board edge and current limiting resistors & near STK IC's.................HTH........................T.

Most H-line Toshiba's have them......

You must have checked fusible resistor?
check convergance control panel and check voltage supply to this board.If voltage are o.k than you have to change convergance control ic which is smd ic and its on the control board.

the ic is getting too much voltage check a diode that feed into the ic it has a short.if you dont locate that defected component it will cost you much more than the set lol.good luck

I doubt it. In a problem like this it could be a power supply that feeds the convergence ic(s). The longer you wait to have this problem taken care of the more of a risk your taking of blowing out the ICs, if there already not bad. Its highly unlikly all three ics went bad at once, unless of a power supply problem. Now this set is not serviceable by the end user as its solid state and all parts are soldered in. Also theres alot of HI Voltage inside this set!! Have the set checked out by a technician ASAP for a bad filter capacitor in the b+ line that feeds the convergence ics Good Luck
