I have hitachi t.v. model p50s601 when i turn it on the picture appeares about 1 second imeddietly turns off when it turns off no audio and no picture. already changed the capacitors on the power board c553-c552 = to 3300uf to 100 volts. checked xbus/xsus apperantly no problem. on the power board there is a voltage of vs=88.3v appeares in seconds then imediatly goes to 0. my question is what else can i check? or what could be the problem? thank you for your assistence.

The main rail voltage is not building up and so there is a possibility of a high drain on the output sections. The +B voltage seems to come up and then flatter off as there is a negative feedback to the processor to cut off ... Flat Panel Televisions

When applying power the AC relays click, after pressing the power button the fans turn on and the optical audio port is red. It will stay 'on' for 3 seconds and then the relays will click on turn off. No red optical light. If I test the P25 connector pin 1 voltage it will go to 15 Volts for about a seconed and then 0. This is only achieved by plugg

RCA TV 32V434T. F 800 was blown. IC 801 pin 1 and 3 was short. I changed IC 801. Then the red lamp in front blinks about 28 sec. Then a click and TV turns off. Have to unplug the TV to start again. IC 860: pin 2 to 8 = 169.3 volts, pin1 to 2 = 8.7 volts (this voltages even after the TV turned off) pin2 to 4 = 2.69 volts (after TV turned off 0 volt). IC 801: pin 4 to minus C 806 = 16 v; after click goes to 4,1 v.Pin 1 to minus C 806 = 160 v; after click goes to 4,8 v. D 869 c = 2,39 v. D 868 c =

I have a sharp lc-19dv27ut tv that is 110 volt. My daughter plugged it into a 220 plug (with the adapter on the end of the power supply cord) but without the voltage converter. She said nothing happened but now the tv will not turn on. No red or greed LED light on the TV. Is the fuse blown or is it TV spent? If it is just a fuse, where can they be purchased and how do I replace them. Thanks for the help.

Sometimes replacing the fuse alone fix the problem,you can buy it at your local electronics supply,it is cheaper than the next parts i'm going to explain.However if you replaced the fuse and nothing happen then you might have an open fusible resistor ... Sharp LC19DV27UT 18.5 in. LCD TV/DVD Combo

I have Mitsubishi wt-42315, I have looked up how to do the self check to determine what may be wrong. It will cut on and a second later it cuts off. I did the self check and it does 2 blink 2 blink.

How do we determine which IC fuse it is?
