If the IC your talking about has a designation number of IC601, the number is MX0841AB-F. Common regulator IC. Sony says that IC is no longer avaialable. You may get lucky and take out the entire G board and have ptscorp.com, or Tristate.com repair the board for you. Good Luck

Check the present power supply [SMPS]; and find out the number of switching regulator IC used. Surf the site with that IC number. You will get similar circuit for SMPS there.

Have Ge model 52GW945 tv, it went blank no picture, nothing, I checked fuse its ok what next


Check the swithed mode power supply section. Some sets uses Ics for control the power regulation, while others uses transistors as oscillators and choppers. If the power to the oscillator section of the SMPS is absent, the supply system won't wake up. So many reasons are there. You just check the resistor, usually connected from main DC rectified supply, to energise the oscillator section of the SMPS. In most sets it may be two resistors in serial, usually 270k 1W*2. If any one of this get opened, the power supply will not start up. Check it first and preceed. If the set uses Ic as regulator controller, check the positive supply voltage at the respective pin of the Ic.

Sometimes when I turn on the tv it doesn't come on


This is a power supply problem, it is the regulator ic's on this board, and a couple of caps that need changed. Sony has used this power supply over many models and the exact component location nubers will change across the diffrent models, but you are looking for two ic's next to to white fuses. ic number is mcz3001

Tv won't turn on


Your problem could be the Convergence board is loading down the power supplies and will not let the TV set come on, or the power/deflection board, part number AA94-08574A, or the STR type regulator IC, part number AA13-00105A. If you locate the convergence board, unplug the connectors, and see if the set will come on. if the set does come on, replace both of the STK convergence IC's at once. The part numbers for those IC's are STK392-40. You can get the original replacement IC's from MCM electronics for about 15 to 16 bucks a piece. Do not use the less expensive STK IC's as they are not the same. the replacement IC's should have the name of SANYO printed right on the face of the IC's. Good Luck

No im sorry to say, not in the standby mode but in the shutdown mode. this could be from several things. like a bad regulator IC in the main supply, or a set of bad capacitors between the main power supply and the sweep power supply, or maybe a shorted audio output IC oer a shorted convergence IC or could even be because fluid leaked down onto the Printed circuit board, from the CRTs. If your not a tech Please call one as it not a place for someone to be tinkering around with! Please dont forget to rate this.
