    Philips lcd 42PFL5432D/37 screen problem

    I repaired a Philips lcd TV model 42PFL5432D/37, no picture and sound, as I knew this is the known issue of the bad caps in the Power board, I repalced the 4 bad caps and TV came to work.
    However, there is a oval shape of white spot (a hat size) in the left bottom of the screen (It's brighter than other area), though I don't know if it's the problem before, or after, as I replaced the smaller caps (I replaced the half value of the original as I couldn't find the match values). The smaller value can lead to the white spot ? Any idea?

    It is never a good idea to go too much higher or lower in capacitance. To get a 42 inch TV working, spend the extra $15 to replace ALL the electrolytic capacitors and the TV will last many more years.

    I can understand "cheaping" out if this was a crummy 15 inch 10 year lcd monitor.
