Toshiba TV model CZ27V51 - Picture+Audo Off, Red light flashing

I have a 27 inch Toshiba TV model CZ27V51. Picture and audio gooff and the red power light on front of set starts flashing (but theset is still on because it can be turned off with the remote and aflash of light is seen as it shuts off). I took the back off andfound by propping up the back end of the circuit board (flexing theboard) I could solve the problem for varying periods of time. So, IInspected the board carefully, looking for broken traces, loose pins,cracks in solder, cracks in the circuit board - anything that might beforced into electrical contact by flexing the circuit board. Found nothing. Then, I theorized one of the voltages coming fromthe power supply could be the problem...so, I inspected that area ofthe circuit board but still nothing. Can you tell me specificallyhow to fix this and where on the circuit board to look? Thank You.

    You say you could not find any
    bad connections.... but do you know HOW to locate them ? Some joints
    can look perfectly normal to someone who is not experienced but be in
    fact a bad joint

    ============

    good point Andy...I may not know how. However, I did flex the board as I looked.



    I don't know how this works...but for a small cash
    fee arranged through this site, I can give you more specific
    information on what to look for.

    =========================

    Yes...I have tried that 3 times but FixYa's system won't work. I
    double checked and triple checked to see that all of the information I
    entered was correct and in the right place. But to no
    avail....FixYa's system is messed up. So, I am frustrated because
    I really need help today while I have a chance to work on the CZ27V51

    Thanks for your help, Andy.

If you can make the set act up by flexing the board, it certainly sounds like a bad connection. I worked on this specific set before and am well aware of some problems with it. You say you could not find any bad connections.... but do you know HOW to locate them ? Some joints can look perfectly normal to someone who is not experienced but be in fact a bad joint. I don't know how this works...but for a small cash fee arranged through this site, I can give you more specific information on what to look for.

    Well, I fixed a couple of symptoms just like the ones you describe but it took me hours of troubleshooting time to find the problem. I think I will be happy with a small cash payment for giving you this information. However I still can't guarantee that it will work for you. I can tell you for sure it did work for me after hours of work to find the problem. Please post your private email address and we'll take it from there. Thanks

Sony 27"TV will not turn on


The picture tube on your tv is dead, you need to replace it. It probably will be worthing just purchasing a new set, because the cost of repairing it will be close to the purchase of a new one.

No sound or picture now


The set may have shorted the horizontal out put transistor since it kept coming on sometimes. This could be cause by the driver transformer arcing causing a "spike" in voltage going to you horizoltal out put transistor. Stargazer

You may have a bad solder joint on the horizontal driver transformer or somewhere else in the set. I found this problem with this transformer several times. Stargazer
