Question about Philips 27PT543S 27" TV

Mitsubishi WT-42311 My t.v. doesn't turn on when the power button is pushed. When I press input and menu code "22" flashes. This a warning for "short protect" I am not sure where to start looking for the problem. The fuse near the power supply does not look to blown. Can anyone help me with this problem. I have the service manual but, it only tells me the dignoses, it does not explain what the actaul problem could be. Tanks a million!

Open 9a05 circuit protect on -24 volt. Also replace both STK392-110 convergence ICs. Use Sanyo replacement only. The others won't last.

My WT-42311 Turns off within 2 seconds when I hit Power on. I hit the Menu & Input button and I get the 2x2 result. What does this mean?

My best guess is that the convergence IC's have failed and blown the +24 volt and/or the -24 volt fuses.

Have you acessed the power indicator error code by pressing in the menu and input buttons on the front of the set both in together and hold in for 5 seconds? The led will blink a series of blinks to indicate a 2 digit code which will repeat several times. Let me know what the blink seqience is.

When i press power the timer light flashes and the T.V. turns on and right back off.

If model number is WT-42311 do the self check the set has.

When power light comes on and then goes off, on front of set press both the Menu and Input (device) buttons at the same time and hold for at least 5 seconds and then release both buttons.

Power light will blink a two digit error code like: 2 blinks, 2 blinks, a pause and the repeat the code several times.

Let me know what the error code is and I will tell you what it means.

WT 42311 won't power up

All that is wrong is the Convergence IS's. They are located on the deflection board (IC8C01 and IC8C02) and are mounted to a very large heat sink. They are black and are STK IC's, STK392-110. Replace both IC's with STK392-120 and you're in business. The -120's are and upgrade and have a higher amp rating. The IC's can be found anywhere on the internet for $9.99 and up. Check Electronix.com, MCM Electonics, Mat Electeonics for starters. Gook luck. Gary D.

My t.v. dont stay on

Hi,

First do a hard reset. Merely unplug the power cord for 4 hours, then restart it. This will correct it if the cause is corrupted soft codes.

If not, the protection circuit has captured the power management and you must have it looked at by a service tech.

Let me know if there is more.
