Question about Panasonic PT-51HX41 51" Rear Projection Television

Pt-51hx42f 3 red blinking lights come on when i try to turn on tv

Hey I noticed you really know what your talking about when it comes to fixing tv's! I have a problem myself, I have a pt-51hx42f and when i try to turn it on it just blinks the red power light 3 times, if I unplug it and turn it on, it seems like it is going to come on but then shuts off and gives the 3 red blinks. I know it is probably the stk392-110 and resistors because I already noticed they are burnt. I was wondering if you could help walk me through putting in the stk392-150's (went with those instead of stk392-110's).

Hi friend i appreciate the words of praise that you have given, but i only know what i have studied and still do study. i also learn more as i repair more. i wish i could give you an answer to the three blinks, but panasonic does not share its information as freely as sony. i will tell you this. i have replaced the convergence chips before. i have seen the burned resistors before. and i have seen the set come on and last from one day to one week. if you are going to get chips i would replace all of them and i would definitely not go cheap. the cheap burn out fast. sometimes you will luck up and get some good ones and sometimes you will not. when i have convergence problems i replace the board. (partstore.com) this way you eliminate changing cap, resistors and a host of other problems. the really good chips cost around $46 a piece, the board cost around $160. now since you do have them. cut the legs off close to the board and simply desolder them one at a time. then take your time and resolder the others. this has to be a skill of patience, but i know you will triumph. tell me also what was your tv doing before it went out completely. please rate my solution and thank you, you are very kind.

I have a 51" Panasonic Rear Projection HDTV,


Try disconnecting all of your HDMI cables and plugging the power cord of the TV into another wall outlet. If this resolves the issue, you may have had a small power surge from either your wall outlet or one of your source devices. It is recommended to connect your TV to a surge protector if you haven't done so already.

You need to replace the "Lamp" check Google Shopping for pricing. Enter your TV model # and add the word "Lamp" Make sure you get a Phillips or Panasonic lamp don't get a Chinese knockoff. They don't last!. Hopr this helps.

Sometimes, in the Panasonic projection sets, one of the convergence IC's shorts out and draws so much current that one of the resistors next to it glows red hot. The computer senses the extra current and shuts the set back off. This is quite an easy problem to correct, but the set should be serviced by a qualified tech familiar with panasonic projection sets.
