Television went off by itself. power but keeps flashing. i unplugged the set for about 1 hour. it turned on but the picture was very bright with washed out colors. there are severl swirly lines on the screen in red green and i belive blue. i unplugged the tv again for several hours and the same thing was found when i turned it back on. this time however, after being on for 1 hour it shut itself off and now the power button is blinking again. the set is 2 years and 6 months old.
i live in the new orleans area. so if you know of anyone or if anyone know how i might be able to fix the problem..........i would greatly appreciate it. tv is out of warranty.

Re: pt 56tw53 picture trouble
I had the same problem with my TV, It seems the high voltage trasnformer blew which in turn casued the pin cushion?? to blow. It then shuts the tv off to prevent more damage to it.
$500 with service charges to get it fixed!

Based upon your description, the problem area is the convergence circuit. These sets usually have a couple of large black ICs that control the convergence. These Ics either have bad connections on the pins or are failing. You can try resoldering the pins of these ICs if you can solder, or replace them. These ICs are usually marked STKxxx and are attached to a heatsink.
If you get this repaired, expect to pay about $30-$40 for each IC (there can be 2) along with the local labor rate for projection sets.
Possible fault in the power supply section of the Tv, the SMPS, it might be cutting off due to a current limiting function in the circuit. make sure that the connectors are tight specially the ground to the power supply. The other fault can be the lamp itself as it can be defective. make sure that the connections to the lamps are tight. A cross check onthe voltage of the circuit+B can be useful to determine the missing problem.
Lamp could still be going out they only last for 5,000 hrs some 8,000 playing hours.
Check the Lamp Fan if it stops running when Lamp turns on set will turn OFF.
But if you have never replaced Lamp Problem will be the Lamp Mats Has them for $99.00
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 numberAA13-00105A. 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
