Bulb is only 2 mo. old. i have sound but no picture. red light is on. tv shuts itself off

step 1. Try pressing reset button. step 2 if step 1 does not work. Remove front cover and lamp door press, defeat the safety switch with a screw to hold the lamp door switch in and check to see if the lamp turns on. If it turns on for up to 10 sec then turns off replace thermal fuse.

Tv turns off (both video and sound) after running for 20 sec and then turns on after 20 sec. This pattern continues over and over. None of the lights are blinking. Lamp is less than 2 yrs old and is...

TV will show Lamp Light warning if lamp got broken or dead.
Symptoms of TV shows lamp is weak and will be replaced. Weak lamp consume more current than allowed ratings and causing activation of protection circuit that shuts off TV and TV turns on again itself, that is why no blinking red light.
Please replace lamp in your Sony KDF-E55A20 TV, lamp replacement procedure is easy and written in user manual, click Sony Support to download user manual copy, if required.
Always buy Sony original lamp for TV safety, Sony original lamp is available in Sony Accessories Store for $200 with following part number..

Please count red light flashes and let me know. There would be long pause between flashes so count pause to pause. It is an error code of TV problem.

TV shut off while watching and won't come back on

It seems this is a self diagnostic function. the official sony codes are as follows

  • Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.
  • Six blinks - No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately. Check C515 & 516 and the jungle IC, IC206.
It sounds like you have a video input problem. Have you unhooked all inputs from the TV and tried to power it back on by itself? Hope this helps

Covergence problem

your set has indications of several problems. red green and blue. indcate convegence issue. the fact that the picture is concave is a indication of totall loss of covergence power supply. the convegence menu missing idicate loss of some voltages from what know as the flyback.AND SHUTDOWN. indicate further problems. generally when convergence fails ..not always the set wont shut down. it could be a simple issue but further trobleshooting would have to occur to narrow it down.
