    Call a distributor that sales parts like Fox International, ph#1-800-321-6992 or Vance Baldwin at 1-800-552-1431. One of these two distributors can look it up for you, make sure you brand name, model,and serial # of T.V.Look beside part and location available then they can look up the part for you. DOVECAT.

Depending on which chip is blown, there could be something else that took it out. Fox International can tell you the part number if you can tell then the IC# that is printed on the pc board next to it or on the underside below it..The number above should work to contact Fox....

    Sorry ! whatever message you left me was either deleted by the administrators or for some reason I am unable to view it. It is a shame we are not allowed to post private email address, even by choice, because this will make things run much smoother. I want to help you privately, but I can't.

    This is a standard vertical chip you can find it anywhere. Just call an electronics distributor like MCM Alectronics or MAT Electronics... and tell them you want vertical chip # TDA7531. That's all you have to say. And since your problem is in the vertical section, make sure to check capacitor C2465 10uf /100v it causes lots of vertical problems. It's better just to replace it anyway. Good luck.

The only way now would be to get the service manual I'm afraid. Good Luck

    OK I looked on a set that is close to your set. The IC marked 7531, and it is the control IC for the power supply? If so, there are some legs that are cut off it shows on this print as7531 is a TEA1620. I am not sure if this is the same as your set though.

Sony KV-35s26 Chassis AA-2D problem

well I thought they had one there but it looks like they only have other chassis # and I have been looking to try and find your chassis # but the only ones ask for money to get it , but I have found some codes and remedy's for your chassi , you had a 5 blinking code which the diagnosis would be this
5 times, Diagnosis: White balance failure (Not balanced) Possible causes: Video out (IC7101, 7201, 7301) is faulty (CR, CG, CB board), CRT drive (IC309) is faulty (A board), G2 is improperly adjusted. Symptoms of the problem: No raster is generated, CRT cathode current detection reference pulse output is small.
if the blink code is now different then let me know what it is and i'll give you that diagnosis

That is a M134C chassis - one of the most inexpensive (throw-away) chassis ever built and the so-called v-chip is actaully a function of the micro, short for micro controller Ic. It would be less expensive to replace the entire board, RCA p/n# 268733 which is around $70.00 bucks plus shipping, than to replace just the micro.
You can find them available at Vance Baldwin... Just login as guest and enter thr RCA part number above and order it there.
Putting in an entire chassis is a plug-n-play repair...
Hope this helps.
